745a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
746
c1989552 747Within the MSYS shell, configure and make with:
d0e1cd3d 748
c1989552 749@example
1a04d4c7 750./configure --enable-memalign-hack
c1989552
RP
751make
752make install
753@end example
d0e1cd3d 754
c1989552
RP
755This will install @file{ffmpeg.exe} along with many other development files
756to @file{/usr/local}. You may specify another install path using the
757@code{--prefix} option in @file{configure}.

d0e1cd3d 762

RP
763@item Building natively using MSYS can be sped up by disabling implicit rules
764in the Makefile by calling @code{make -r} instead of plain @code{make}. This
765speed up is close to non-existent for normal one-off builds and is only
766noticeable when running make for a second time (for example in
767@code{make install}).
768
c1989552
RP
769@item In order to compile FFplay, you must have the MinGW development library
770of SDL. Get it from @url{http://www.libsdl.org}.
771Edit the @file{bin/sdl-config} script so that it points to the correct prefix
772where SDL was installed. Verify that @file{sdl-config} can be launched from
773the MSYS command line.
d0e1cd3d 774
d0e1cd3d 775@item By using @code{./configure --enable-shared} when configuring FFmpeg,
c1989552 776you can build libavutil, libavcodec and libavformat as DLLs.

d0e1cd3d 781
c1989552
RP
782As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
783want to use the libav* libraries in your own applications, you can still
784compile those applications using MSVC++. But the libav* libraries you link
785to @emph{must} be built with MinGW. However, you will not be able to debug
786inside the libav* libraries, since MSVC++ does not recognize the debug
787symbols generated by GCC.
788We strongly recommend you to move over from MSVC++ to MinGW tools.
d0e1cd3d 789
c1989552
RP
790This description of how to use the FFmpeg libraries with MSVC++ is based on
791Microsoft Visual C++ 2005 Express Edition. If you have a different version,
792you might have to modify the procedures slightly.
d0e1cd3d 793
c1989552 794@subsubsection Using static libraries
d0e1cd3d 795
c1989552 796Assuming you have just built and installed FFmpeg in @file{/usr/local}.
d0e1cd3d
DB
797
798@enumerate
799
800@item Create a new console application ("File / New / Project") and then
801select "Win32 Console Application". On the appropriate page of the
802Application Wizard, uncheck the "Precompiled headers" option.
803
804@item Write the source code for your application, or, for testing, just
805copy the code from an existing sample application into the source file
c1989552 806that MSVC++ has already created for you. For example, you can copy
d95a0c67 807@file{libavformat/output-example.c} from the FFmpeg distribution.
d0e1cd3d
DB
808
809@item Open the "Project / Properties" dialog box. In the "Configuration"
810combo box, select "All Configurations" so that the changes you make will
811affect both debug and release builds. In the tree view on the left hand
812side, select "C/C++ / General", then edit the "Additional Include
c1989552
RP
813Directories" setting to contain the path where the FFmpeg includes were
814installed (i.e. @file{c:\msys\1.0\local\include}).
f010d377
RP
815Do not add MinGW's include directory here, or the include files will
816conflict with MSVC's.
c1989552
RP
817
818@item Still in the "Project / Properties" dialog box, select
819"Linker / General" from the tree view and edit the
820"Additional Library Directories" setting to contain the @file{lib}
821directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
822the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
823and the directory where MinGW's GCC libs are installed
824(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
825"Linker / Input" from the tree view, and add the files @file{libavformat.a},
826@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
827@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
828to the end of "Additional Dependencies".
d0e1cd3d
DB
829
830@item Now, select "C/C++ / Code Generation" from the tree view. Select
831"Debug" in the "Configuration" combo box. Make sure that "Runtime
832Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
833the "Configuration" combo box and make sure that "Runtime Library" is
834set to "Multi-threaded DLL".
835
c1989552
RP
836@item Click "OK" to close the "Project / Properties" dialog box.
837
838@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
839Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
840and install it in MSVC++'s include directory
841(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
842
843@item MSVC++ also does not understand the @code{inline} keyword used by
844FFmpeg, so you must add this line before @code{#include}ing libav*:
845@example
846#define inline _inline
847@end example
848
c1989552
RP
849@item Build your application, everything should work.
850
851@end enumerate
852
853@subsubsection Using shared libraries
854
855This is how to create DLL and LIB files that are compatible with MSVC++:
856
857@enumerate
858
859@item Add a call to @file{vcvars32.bat} (which sets up the environment
860variables for the Visual C++ tools) as the first line of @file{msys.bat}.
861The standard location for @file{vcvars32.bat} is
862@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
863and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
864If this corresponds to your setup, add the following line as the first line
865of @file{msys.bat}:
866
867@example
868call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
869@end example
870
871Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
872and run @file{c:\msys\1.0\msys.bat} from there.
873
874@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
875from @file{Microsoft (R) Library Manager}, this means your environment
876variables are set up correctly, the @file{Microsoft (R) Library Manager}
877is on the path and will be used by FFmpeg to create
878MSVC++-compatible import libraries.
879
880@item Build FFmpeg with
881
882@example
883./configure --enable-shared --enable-memalign-hack
884make
885make install
886@end example
887
888Your install path (@file{/usr/local/} by default) should now have the
889necessary DLL and LIB files under the @file{bin} directory.
d0e1cd3d
DB
890
891@end enumerate
892
c1989552
RP
893To use those files with MSVC++, do the same as you would do with
894the static libraries, as described above. But in Step 4,
895you should only need to add the directory where the LIB files are installed
896(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
897installed in the @file{bin} directory. And instead of adding @file{libxx.a}
898files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
899@file{avutil.lib}. There should be no need for @file{libmingwex.a},
900@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
901statically linked into the DLLs. The @file{bin} directory contains a bunch
902of DLL files, but the ones that are actually used to run your application
903are the ones with a major version number in their filenames
904(i.e. @file{avcodec-51.dll}).
905
d0e1cd3d
DB
906@subsection Cross compilation for Windows with Linux
907
908You must use the MinGW cross compilation tools available at
909@url{http://www.mingw.org/}.
910
911Then configure FFmpeg with the following options:
912@example
913./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
914@end example
915(you can change the cross-prefix according to the prefix chosen for the
916MinGW tools).
917
918Then you can easily test FFmpeg with Wine
919(@url{http://www.winehq.com/}).
920
921@subsection Compilation under Cygwin
922
8484503e
VP
923The main issue with the 1.5.x Cygwin versions is that newlib, its C library,
924does not contain llrint(). You need to upgrade to the unstable 1.7.x versions,
925or leverage the implementation in MinGW (as explained below).
d0e1cd3d
DB
926
927Just install your Cygwin with all the "Base" packages, plus the
928following "Devel" ones:
929@example
71ecc16b
RP
930binutils, gcc-core, make, subversion, mingw-runtime
931@end example
932
933And the following "Utils" one:
934@example
935diffutils
d0e1cd3d
DB
936@end example
937
666a1b34
VP
938The experimental gcc4 package is still buggy, hence please
939use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.
940
8484503e
VP
941Install the current binutils-20080624-2 as they work fine (the old
942binutils-20060709-1 proved buggy on shared builds).
d0e1cd3d 943
29c3d42b
VP
944Then create a small library that just contains llrint():
945
946@example
947ar x /usr/lib/mingw/libmingwex.a llrint.o
948ar cq /usr/local/lib/libllrint.a llrint.o
949@end example
950
d0e1cd3d
DB
951Then run
952
953@example
29c3d42b 954./configure --enable-static --disable-shared --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
955@end example
956
957to make a static build or
958
959@example
29c3d42b 960./configure --enable-shared --disable-static --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
961@end example
962
963to build shared libraries.
964
965If you want to build FFmpeg with additional libraries, download Cygwin
5dd9799d
VP
966"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
967@example
968libogg-devel, libvorbis-devel
969@end example
970
971These library packages are only available from Cygwin Ports
be8497b0 972(@url{http://sourceware.org/cygwinports/}) :
5dd9799d
VP
973
974@example
975yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
976libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
977libxvidcore-devel
978@end example
979
980The recommendation for libnut and x264 is to build them from source by
981yourself, as they evolve too quickly for Cygwin Ports to be up to date.
d0e1cd3d 982
cdf51395
VP
983Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
984of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
985
d0e1cd3d
DB
986@subsection Crosscompilation for Windows under Cygwin
987
988With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
989
990Just install your Cygwin as explained before, plus these additional
991"Devel" packages:
992@example
993gcc-mingw-core, mingw-runtime, mingw-zlib
994@end example
995
996and add some special flags to your configure invocation.
997
998For a static build run
999@example
1000./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1001@end example
1002
1003and for a build with shared libraries
1004@example
1005./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1006@end example
