762Some parts of FFmpeg cannot be built with version 2.15 of the GNU
763assembler which is still provided by a few AMD64 distributions. To
764make sure your compiler really uses the required version of gas
765after a binutils upgrade, run:
766
767@example
768$(gcc -print-prog-name=as) --version
769@end example
770
771If not, then you should install a different compiler that has no
772hard-coded path to gas. In the worst case pass @code{--disable-asm}

854@item Building natively using MSYS can be sped up by disabling implicit rules
855in the Makefile by calling @code{make -r} instead of plain @code{make}. This
856speed up is close to non-existent for normal one-off builds and is only
857noticeable when running make for a second time (for example in
858@code{make install}).
859
c1989552
RP
860@item In order to compile FFplay, you must have the MinGW development library
861of SDL. Get it from @url{http://www.libsdl.org}.
862Edit the @file{bin/sdl-config} script so that it points to the correct prefix
863where SDL was installed. Verify that @file{sdl-config} can be launched from
864the MSYS command line.
d0e1cd3d 865

873As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
874want to use the libav* libraries in your own applications, you can still
875compile those applications using MSVC++. But the libav* libraries you link
876to @emph{must} be built with MinGW. However, you will not be able to debug
877inside the libav* libraries, since MSVC++ does not recognize the debug
878symbols generated by GCC.
879We strongly recommend you to move over from MSVC++ to MinGW tools.
d0e1cd3d 880
c1989552
RP
881This description of how to use the FFmpeg libraries with MSVC++ is based on
882Microsoft Visual C++ 2005 Express Edition. If you have a different version,
883you might have to modify the procedures slightly.
d0e1cd3d 884
c1989552 885@subsubsection Using static libraries
d0e1cd3d 886
c1989552 887Assuming you have just built and installed FFmpeg in @file{/usr/local}.
d0e1cd3d
DB
888
889@enumerate
890
891@item Create a new console application ("File / New / Project") and then
892select "Win32 Console Application". On the appropriate page of the
893Application Wizard, uncheck the "Precompiled headers" option.
894
895@item Write the source code for your application, or, for testing, just
896copy the code from an existing sample application into the source file
c1989552 897that MSVC++ has already created for you. For example, you can copy
d95a0c67 898@file{libavformat/output-example.c} from the FFmpeg distribution.
d0e1cd3d
DB
899
900@item Open the "Project / Properties" dialog box. In the "Configuration"
901combo box, select "All Configurations" so that the changes you make will
902affect both debug and release builds. In the tree view on the left hand
903side, select "C/C++ / General", then edit the "Additional Include
c1989552
RP
904Directories" setting to contain the path where the FFmpeg includes were
905installed (i.e. @file{c:\msys\1.0\local\include}).
f010d377
RP
906Do not add MinGW's include directory here, or the include files will
907conflict with MSVC's.
c1989552
RP
908
909@item Still in the "Project / Properties" dialog box, select
910"Linker / General" from the tree view and edit the
911"Additional Library Directories" setting to contain the @file{lib}
912directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
913the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
914and the directory where MinGW's GCC libs are installed
915(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
916"Linker / Input" from the tree view, and add the files @file{libavformat.a},
917@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
918@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
919to the end of "Additional Dependencies".
d0e1cd3d
DB
920
921@item Now, select "C/C++ / Code Generation" from the tree view. Select
922"Debug" in the "Configuration" combo box. Make sure that "Runtime
923Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
924the "Configuration" combo box and make sure that "Runtime Library" is
925set to "Multi-threaded DLL".
926
c1989552
RP
927@item Click "OK" to close the "Project / Properties" dialog box.
928
929@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
930Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
931and install it in MSVC++'s include directory
932(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
933
934@item MSVC++ also does not understand the @code{inline} keyword used by
935FFmpeg, so you must add this line before @code{#include}ing libav*:
936@example
937#define inline _inline
938@end example
939
c1989552
RP
940@item Build your application, everything should work.
941
942@end enumerate
943
944@subsubsection Using shared libraries
945
946This is how to create DLL and LIB files that are compatible with MSVC++:
947
948@enumerate
949
950@item Add a call to @file{vcvars32.bat} (which sets up the environment
951variables for the Visual C++ tools) as the first line of @file{msys.bat}.
952The standard location for @file{vcvars32.bat} is
953@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
954and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
955If this corresponds to your setup, add the following line as the first line
956of @file{msys.bat}:
957
958@example
959call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
960@end example
961
962Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
963and run @file{c:\msys\1.0\msys.bat} from there.
964
965@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
966from @file{Microsoft (R) Library Manager}, this means your environment
967variables are set up correctly, the @file{Microsoft (R) Library Manager}
968is on the path and will be used by FFmpeg to create
969MSVC++-compatible import libraries.
970
971@item Build FFmpeg with
972
973@example
974./configure --enable-shared --enable-memalign-hack
975make
976make install
977@end example
978
979Your install path (@file{/usr/local/} by default) should now have the
980necessary DLL and LIB files under the @file{bin} directory.
d0e1cd3d
DB
981
982@end enumerate
983
c1989552
RP
984To use those files with MSVC++, do the same as you would do with
985the static libraries, as described above. But in Step 4,
986you should only need to add the directory where the LIB files are installed
987(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
bc3836a1
RP
988installed in the @file{bin} directory. And instead of adding the static
989libraries (@file{libxxx.a} files) you should add the MSVC import libraries
737eb597 990(@file{avcodec.lib}, @file{avformat.lib}, and
bc3836a1
RP
991@file{avutil.lib}). Note that you should not use the GCC import
992libraries (@file{libxxx.dll.a} files), as these will give you undefined
993reference errors. There should be no need for @file{libmingwex.a},
c1989552
RP
994@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
995statically linked into the DLLs. The @file{bin} directory contains a bunch
996of DLL files, but the ones that are actually used to run your application
997are the ones with a major version number in their filenames
998(i.e. @file{avcodec-51.dll}).
999
e16c1569
RP
1000FFmpeg headers do not declare global data for Windows DLLs through the usual
1001dllexport/dllimport interface. Such data will be exported properly while
1002building, but to use them in your MSVC++ code you will have to edit the
1003appropriate headers and mark the data as dllimport. For example, in
1004libavutil/pixdesc.h you should have:
1005@example
1006extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
1007@end example
1008
d0e1cd3d
DB
1009@subsection Cross compilation for Windows with Linux
1010
1011You must use the MinGW cross compilation tools available at
1012@url{http://www.mingw.org/}.
1013
1014Then configure FFmpeg with the following options:
1015@example
1016./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
1017@end example
1018(you can change the cross-prefix according to the prefix chosen for the
1019MinGW tools).
1020
1021Then you can easily test FFmpeg with Wine
1022(@url{http://www.winehq.com/}).
1023
1024@subsection Compilation under Cygwin

1045
2f821b03
VP
1046to make a static build.
1047
1048The current @code{gcc4-core} package is buggy and needs this flag to build
1049shared libraries:
d0e1cd3d

1076@subsection Crosscompilation for Windows under Cygwin
1077
1078With Cygwin you can create Windows binaries that do not need the cygwin1.dll.

1081"Devel" packages:
1082@example
1083gcc-mingw-core, mingw-runtime, mingw-zlib
1084@end example
1085
1086and add some special flags to your configure invocation.
