756Some parts of FFmpeg cannot be built with version 2.15 of the GNU
757assembler which is still provided by a few AMD64 distributions. To
758make sure your compiler really uses the required version of gas
759after a binutils upgrade, run:
760
761@example
762$(gcc -print-prog-name=as) --version
763@end example
764
765If not, then you should install a different compiler that has no
766hard-coded path to gas. In the worst case pass @code{--disable-asm}
767to configure.

d0e1cd3d 847
b94ca208
RP
848@item Building natively using MSYS can be sped up by disabling implicit rules
849in the Makefile by calling @code{make -r} instead of plain @code{make}. This
850speed up is close to non-existent for normal one-off builds and is only
851noticeable when running make for a second time (for example in
852@code{make install}).
853
c1989552
RP
854@item In order to compile FFplay, you must have the MinGW development library
855of SDL. Get it from @url{http://www.libsdl.org}.
856Edit the @file{bin/sdl-config} script so that it points to the correct prefix
857where SDL was installed. Verify that @file{sdl-config} can be launched from
858the MSYS command line.
d0e1cd3d 859
d0e1cd3d 860@item By using @code{./configure --enable-shared} when configuring FFmpeg,

867As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
868want to use the libav* libraries in your own applications, you can still
869compile those applications using MSVC++. But the libav* libraries you link
870to @emph{must} be built with MinGW. However, you will not be able to debug
871inside the libav* libraries, since MSVC++ does not recognize the debug
872symbols generated by GCC.
873We strongly recommend you to move over from MSVC++ to MinGW tools.
d0e1cd3d 874
c1989552
RP
875This description of how to use the FFmpeg libraries with MSVC++ is based on
876Microsoft Visual C++ 2005 Express Edition. If you have a different version,
877you might have to modify the procedures slightly.
d0e1cd3d 878
c1989552 879@subsubsection Using static libraries
d0e1cd3d 880
c1989552 881Assuming you have just built and installed FFmpeg in @file{/usr/local}.
d0e1cd3d
DB
882
883@enumerate
884
885@item Create a new console application ("File / New / Project") and then
886select "Win32 Console Application". On the appropriate page of the
887Application Wizard, uncheck the "Precompiled headers" option.
888
889@item Write the source code for your application, or, for testing, just
890copy the code from an existing sample application into the source file
c1989552 891that MSVC++ has already created for you. For example, you can copy
d95a0c67 892@file{libavformat/output-example.c} from the FFmpeg distribution.
d0e1cd3d
DB
893
894@item Open the "Project / Properties" dialog box. In the "Configuration"
895combo box, select "All Configurations" so that the changes you make will
896affect both debug and release builds. In the tree view on the left hand
897side, select "C/C++ / General", then edit the "Additional Include
c1989552
RP
898Directories" setting to contain the path where the FFmpeg includes were
899installed (i.e. @file{c:\msys\1.0\local\include}).
f010d377
RP
900Do not add MinGW's include directory here, or the include files will
901conflict with MSVC's.
c1989552
RP
902
903@item Still in the "Project / Properties" dialog box, select
904"Linker / General" from the tree view and edit the
905"Additional Library Directories" setting to contain the @file{lib}
906directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
907the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
908and the directory where MinGW's GCC libs are installed
909(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
910"Linker / Input" from the tree view, and add the files @file{libavformat.a},
911@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
912@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
913to the end of "Additional Dependencies".
d0e1cd3d
DB
914
915@item Now, select "C/C++ / Code Generation" from the tree view. Select
916"Debug" in the "Configuration" combo box. Make sure that "Runtime
917Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
918the "Configuration" combo box and make sure that "Runtime Library" is
919set to "Multi-threaded DLL".
920
c1989552
RP
921@item Click "OK" to close the "Project / Properties" dialog box.
922
923@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
924Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
925and install it in MSVC++'s include directory
926(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
927
928@item MSVC++ also does not understand the @code{inline} keyword used by
929FFmpeg, so you must add this line before @code{#include}ing libav*:
930@example
931#define inline _inline
932@end example
933
c1989552
RP
934@item Build your application, everything should work.
935
936@end enumerate
937
938@subsubsection Using shared libraries
939
940This is how to create DLL and LIB files that are compatible with MSVC++:
941
942@enumerate
943
944@item Add a call to @file{vcvars32.bat} (which sets up the environment
945variables for the Visual C++ tools) as the first line of @file{msys.bat}.
946The standard location for @file{vcvars32.bat} is
947@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
948and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
949If this corresponds to your setup, add the following line as the first line
950of @file{msys.bat}:
951
952@example
953call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
954@end example
955
956Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
957and run @file{c:\msys\1.0\msys.bat} from there.
958
959@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
960from @file{Microsoft (R) Library Manager}, this means your environment
961variables are set up correctly, the @file{Microsoft (R) Library Manager}
962is on the path and will be used by FFmpeg to create
963MSVC++-compatible import libraries.
964
965@item Build FFmpeg with
966
967@example
968./configure --enable-shared --enable-memalign-hack
969make
970make install
971@end example
972
973Your install path (@file{/usr/local/} by default) should now have the
974necessary DLL and LIB files under the @file{bin} directory.
d0e1cd3d
DB
975
976@end enumerate
977
c1989552
RP
978To use those files with MSVC++, do the same as you would do with
979the static libraries, as described above. But in Step 4,
980you should only need to add the directory where the LIB files are installed
981(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
bc3836a1
RP
982installed in the @file{bin} directory. And instead of adding the static
983libraries (@file{libxxx.a} files) you should add the MSVC import libraries
984(@file{avcodec.lib}, @file{avformat.lib}, @file{avcore.lib}, and
985@file{avutil.lib}). Note that you should not use the GCC import
986libraries (@file{libxxx.dll.a} files), as these will give you undefined
987reference errors. There should be no need for @file{libmingwex.a},
c1989552
RP
988@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
989statically linked into the DLLs. The @file{bin} directory contains a bunch
990of DLL files, but the ones that are actually used to run your application
991are the ones with a major version number in their filenames
992(i.e. @file{avcodec-51.dll}).
993
e16c1569
RP
994FFmpeg headers do not declare global data for Windows DLLs through the usual
995dllexport/dllimport interface. Such data will be exported properly while
996building, but to use them in your MSVC++ code you will have to edit the
997appropriate headers and mark the data as dllimport. For example, in
998libavutil/pixdesc.h you should have:
999@example
1000extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
1001@end example
1002
d0e1cd3d
DB
1003@subsection Cross compilation for Windows with Linux
1004
1005You must use the MinGW cross compilation tools available at
1006@url{http://www.mingw.org/}.
1007
1008Then configure FFmpeg with the following options:
1009@example
1010./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
1011@end example
1012(you can change the cross-prefix according to the prefix chosen for the
1013MinGW tools).
1014
1015Then you can easily test FFmpeg with Wine
1016(@url{http://www.winehq.com/}).
1017
1018@subsection Compilation under Cygwin

1038@end example
1039
2f821b03
VP
1040to make a static build.
1041
1042The current @code{gcc4-core} package is buggy and needs this flag to build
1043shared libraries:
d0e1cd3d
DB
1044
1045@example
2f821b03 1046./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions
d0e1cd3d
DB
1047@end example
1048
d0e1cd3d 1049If you want to build FFmpeg with additional libraries, download Cygwin
5dd9799d
VP
1050"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
1051@example
1052libogg-devel, libvorbis-devel

1054
1055These library packages are only available from Cygwin Ports

1063
1064The recommendation for libnut and x264 is to build them from source by
1065yourself, as they evolve too quickly for Cygwin Ports to be up to date.

1070@subsection Crosscompilation for Windows under Cygwin
1071
1072With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
1073
1074Just install your Cygwin as explained before, plus these additional
1075"Devel" packages:
1076@example
1077gcc-mingw-core, mingw-runtime, mingw-zlib
1078@end example
1079
1080and add some special flags to your configure invocation.
1081
1082For a static build run
1083@example
1084./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
