In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

Introduction LibTorrent depends on the client to handle http downloads, thus the library does not have a dependency on any specific http library. The library provides a base class named torrent::Http with virtual member functions that the client must implement, and a sigc++ slot which must be set to create an instance of the derived torrent::Http class when called. The torrent::Http class and the factory slot related functions can be found in the header "torrent/http.h". The http handler should have reasonable connection timeouts, be non-blocking and not do reconnects on failed downloads.
Factory Slot The client registers the desired factory slot with the static torrent::Http::set_factory member function. Using sigc++ the client may bind values to the arguments of their function to avoid depending on globals. The factory slot must return a pointer to a new instance with the base type torrent::Http, and the caller takes responsibility of deleting the object. (Note: consider making the cleanup a slot)
Output Stream The data downloaded by the http handler is to be written to torrent::Http::m_stream which is a pointer to an std::iostream. The http handler must not change any of the flags on the stream.
Start Http::start is called by the library when it wishes to initiate a http download. Your Http derived class must implement this function. It must be non-blocking and thread-safe. This means that if a seperate thread is used for downloading then it must not emit any signal while the main thread is inside the library.
close Http::close is used bu the library to stop and close a download. No signals may be emited after this. Http::m_data should not be cleared. The library may clear the Http::m_data pointer after this.
Signals There are two mutually exclusive signals that are called when the download has stopped. The signal torrent::Http::m_signalDone is called if the download was successful and torrent::Http::m_stream contains the complete data. Or if the download was unsuccessful for some reason, then torrent::Http::m_signalFailed is called with an error message.

State
Closed This is the initial state of a download. When switching to this mode, all tracker requests are closed and the bitfield of completed chunks is cleared. File paths can only be changed in this state. Functions for getting information on bitfields, chunk count and various others will return size 0 in this state. (TODO: Check which)
torrent::Download::is_open() == false; torrent::Download::is_active() == false; torrent::Download::is_tracker_busy() == false;
Open This is the state after a successfull call to torrent::Download::open(). This function throws torrent::local_error if the download could not be opened. All files in the download have been created and are open. The initial hash check must be done to get a valid bitfield of completed chunks.
torrent::Download::is_open() == true; torrent::Download::is_active() == false;
Active A download is active after calling torrent::Download::start(). Only downloads that are in an open state and has a valid bitfield of completed chunks can be activated.
torrent::Download::is_open() == true; torrent::Download::is_active() == true; torrent::Download::is_hash_checked() == true;
A tracker request will be made when torrent::Download::stop() is called on an active download. It is not required to wait for the tracker request to finish before calling torrent::Download::close(), but it is recommened so the tracker knows this client is not available.
File Paths The paths of files in a Download consists of two parts, the root directory and the paths of each file. The file paths are read from the torrent file and the files usually reside in the root directory. The root directory is by default "./" for single file torrents and "./[torrent_name]/" for multi-file torrents.
// Get and set the root directory. std::string torrent::Download::get_root_dir(); void torrent::Download::set_root_dir(const std::string& dir); // Get the torrent::Entry class for each file in the download. torrent::Entry torrent::Download::get_entry(uint32_t index); uint32_t torrent::Download::get_entry_size(); typedef std::list<std::string> torrent::Entry::Path; // Get and set the file path. std::string torrent::Entry::get_path(); const Path& torrent::Entry::get_path_list(); void torrent::Entry::set_path_list(const Path& l);
The modifications can only be done while the download is in a closed state. Modifying the file paths will not change the "info hash" part of the bencode'd torrent associated with the download. (TODO: When exporting, save root directory and file paths to another section of the torrent)

This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.) If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You only need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not support the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the `--target=TYPE' option to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc will cause the specified gcc to be used as the C compiler (unless it is overridden in the site shell script). `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. libtorrent-0.11.9/install-sh0000755000076500007650000001270110560616250012727 00000000000000#!/bin/sh # # install - install a program, script, or datafile # This comes from X11R5 (mit/util/scripts/install.sh). # # Copyright 1991 by the Massachusetts Institute of Technology # # Permission to use, copy, modify, distribute, and sell this software and its # documentation for any purpose is hereby granted without fee, provided that # the above copyright notice appear in all copies and that both that # copyright notice and this permission notice appear in supporting # documentation, and that the name of M.I.T. not be used in advertising or # publicity pertaining to distribution of the software without specific, # written prior permission.

LIBRARY DEPENDENCIES libsigc++ 2.0 (deb: libsigc++-2.0-dev) g++ >= 3.3 SIGC++ The API will use sigc++ signals to give the client a simple, yet powerful way of reacting to events from the library. The client can hook multiple slots on each signal and modify the parameters to suit the functions. This avoids lots of unnecessary code in the client. POLLING "libtorrent/src/torrent/poll.h" provides an abstract class for implementing any kind of polling the client wishes to use. Currently epoll and select based polling is included.libtorrent-0.11.9/scripts/0000777000076500007650000000000010710121633012466 500000000000000libtorrent-0.11.9/scripts/attributes.m40000644000076500007650000000745210560616003015045 00000000000000# Functions to check for attributes support in compiler AC_DEFUN([CC_ATTRIBUTE_CONSTRUCTOR], [ AC_CACHE_CHECK([if compiler supports __attribute__((constructor))], [cc_cv_attribute_constructor], [AC_COMPILE_IFELSE([ void ctor() __attribute__((constructor)); void ctor() { }; ], [cc_cv_attribute_constructor=yes], [cc_cv_attribute_constructor=no]) ]) if test "x$cc_cv_attribute_constructor" = "xyes"; then AC_DEFINE([SUPPORT_ATTRIBUTE_CONSTRUCTOR], 1, [Define this if the compiler supports the constructor attribute]) $1 else true $2 fi ]) AC_DEFUN([CC_ATTRIBUTE_FORMAT], [ AC_CACHE_CHECK([if compiler supports __attribute__((format(printf, n, n)))], [cc_cv_attribute_format], [AC_COMPILE_IFELSE([ void __attribute__((format(printf, 1, 2))) printflike(const char *fmt, ...) { } ], [cc_cv_attribute_format=yes], [cc_cv_attribute_format=no]) ]) if test "x$cc_cv_attribute_format" = "xyes"; then AC_DEFINE([SUPPORT_ATTRIBUTE_FORMAT], 1, [Define this if the compiler supports the format attribute]) $1 else true $2 fi ]) AC_DEFUN([CC_ATTRIBUTE_INTERNAL], [ AC_CACHE_CHECK([if compiler supports __attribute__((visibility("internal")))], [cc_cv_attribute_internal], [AC_COMPILE_IFELSE([ void __attribute__((visibility("internal"))) internal_function() { } ], [cc_cv_attribute_internal=yes], [cc_cv_attribute_internal=no]) ]) if test "x$cc_cv_attribute_internal" = "xyes"; then AC_DEFINE([SUPPORT_ATTRIBUTE_INTERNAL], 1, [Define this if the compiler supports the internal visibility attribute]) $1 else true $2 fi ]) AC_DEFUN([CC_ATTRIBUTE_VISIBILITY], [ AC_LANG_PUSH(C++) tmp_CXXFLAGS=$CXXFLAGS CXXFLAGS="$CXXFLAGS -fvisibility=hidden" AC_CACHE_CHECK([if compiler supports __attribute__((visibility("default")))], [cc_cv_attribute_visibility], [AC_COMPILE_IFELSE([ void __attribute__((visibility("default"))) visibility_function() { } ], [cc_cv_attribute_visibility=yes], [cc_cv_attribute_visibility=no]) ]) CXXFLAGS=$tmp_CXXFLAGS AC_LANG_POP(C++) if test "x$cc_cv_attribute_visibility" = "xyes"; then AC_DEFINE([SUPPORT_ATTRIBUTE_VISIBILITY], 1, [Define this if the compiler supports the visibility attributes.]) CXXFLAGS="$CXXFLAGS -fvisibility=hidden" $1 else true $2 fi ]) AC_DEFUN([CC_ATTRIBUTE_NONNULL], [ AC_CACHE_CHECK([if compiler supports __attribute__((nonnull()))], [cc_cv_attribute_nonnull], [AC_COMPILE_IFELSE([ void some_function(void *foo, void *bar) __attribute__((nonnull())); void some_function(void *foo, void *bar) { } ], [cc_cv_attribute_nonnull=yes], [cc_cv_attribute_nonnull=no]) ]) if test "x$cc_cv_attribute_nonnull" = "xyes"; then AC_DEFINE([SUPPORT_ATTRIBUTE_NONNULL], 1, [Define this if the compiler supports the nonnull attribute]) $1 else true $2 fi ]) AC_DEFUN([CC_ATTRIBUTE_UNUSED], [ AC_CACHE_CHECK([if compiler supports __attribute__((unused))], [cc_cv_attribute_unused], [AC_COMPILE_IFELSE([ void some_function(void *foo, __attribute__((unused)) void *bar); ], [cc_cv_attribute_unused=yes], [cc_cv_attribute_unused=no]) ]) if test "x$cc_cv_attribute_unused" = "xyes"; then AC_DEFINE([SUPPORT_ATTRIBUTE_UNUSED], 1, [Define this if the compiler supports the unused attribute]) $1 else true $2 fi ]) AC_DEFUN([CC_FUNC_EXPECT], [ AC_CACHE_CHECK([if compiler has __builtin_expect function], [cc_cv_func_expect], [AC_COMPILE_IFELSE([ int some_function() { int a = 3; return (int)__builtin_expect(a, 3); } ], [cc_cv_func_expect=yes], [cc_cv_func_expect=no]) ]) if test "x$cc_cv_func_expect" = "xyes"; then AC_DEFINE([SUPPORT__BUILTIN_EXPECT], 1, [Define this if the compiler supports __builtin_expect() function]) $1 else true $2 fi ]) libtorrent-0.11.9/scripts/checks.m40000644000076500007650000002334310702556063014123 00000000000000AC_DEFUN([TORRENT_CHECK_XFS], [ AC_MSG_CHECKING(for XFS support) AC_COMPILE_IFELSE( [[#include #include int main() { struct xfs_flock64 l; ioctl(0, XFS_IOC_RESVSP64, &l); return 0; } ]], [ AC_DEFINE(USE_XFS, 1, Use XFS filesystem stuff.)
