845in the Makefile by calling @code{make -r} instead of plain @code{make}. This
846speed up is close to non-existent for normal one-off builds and is only
847noticeable when running make for a second time (for example in
848@code{make install}).

d0e1cd3d 862
f8a45fa1 863As stated in the FAQ, Libav will not compile under MSVC++. However, if you
c1989552
RP
864want to use the libav* libraries in your own applications, you can still
865compile those applications using MSVC++. But the libav* libraries you link
866to @emph{must} be built with MinGW. However, you will not be able to debug
867inside the libav* libraries, since MSVC++ does not recognize the debug
868symbols generated by GCC.
869We strongly recommend you to move over from MSVC++ to MinGW tools.
d0e1cd3d 870
f8a45fa1 871This description of how to use the Libav libraries with MSVC++ is based on
c1989552
RP
872Microsoft Visual C++ 2005 Express Edition. If you have a different version,
873you might have to modify the procedures slightly.
d0e1cd3d 874
c1989552 875@subsubsection Using static libraries
d0e1cd3d 876
f8a45fa1 877Assuming you have just built and installed Libav in @file{/usr/local}.
d0e1cd3d
DB
878
879@enumerate
880
881@item Create a new console application ("File / New / Project") and then
882select "Win32 Console Application". On the appropriate page of the
883Application Wizard, uncheck the "Precompiled headers" option.
884
885@item Write the source code for your application, or, for testing, just
886copy the code from an existing sample application into the source file
c1989552 887that MSVC++ has already created for you. For example, you can copy
f8a45fa1 888@file{libavformat/output-example.c} from the Libav distribution.
d0e1cd3d
DB
889
890@item Open the "Project / Properties" dialog box. In the "Configuration"
891combo box, select "All Configurations" so that the changes you make will
892affect both debug and release builds. In the tree view on the left hand
893side, select "C/C++ / General", then edit the "Additional Include
f8a45fa1 894Directories" setting to contain the path where the Libav includes were
c1989552 895installed (i.e. @file{c:\msys\1.0\local\include}).
f010d377
RP
896Do not add MinGW's include directory here, or the include files will
897conflict with MSVC's.
c1989552
RP
898
899@item Still in the "Project / Properties" dialog box, select
900"Linker / General" from the tree view and edit the
901"Additional Library Directories" setting to contain the @file{lib}
f8a45fa1 902directory where Libav was installed (i.e. @file{c:\msys\1.0\local\lib}),
c1989552
RP
903the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
904and the directory where MinGW's GCC libs are installed
905(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
906"Linker / Input" from the tree view, and add the files @file{libavformat.a},
907@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
908@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
909to the end of "Additional Dependencies".
d0e1cd3d
DB
910
911@item Now, select "C/C++ / Code Generation" from the tree view. Select
912"Debug" in the "Configuration" combo box. Make sure that "Runtime
913Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
914the "Configuration" combo box and make sure that "Runtime Library" is
915set to "Multi-threaded DLL".
916
c1989552
RP
917@item Click "OK" to close the "Project / Properties" dialog box.
918
f8a45fa1 919@item MSVC++ lacks some C99 header files that are fundamental for Libav.
c1989552
RP
920Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
921and install it in MSVC++'s include directory
922(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
923
924@item MSVC++ also does not understand the @code{inline} keyword used by
f8a45fa1 925Libav, so you must add this line before @code{#include}ing libav*:
c1989552
RP
926@example
927#define inline _inline
928@end example
929
c1989552
RP
930@item Build your application, everything should work.
931
932@end enumerate
933
934@subsubsection Using shared libraries
935
936This is how to create DLL and LIB files that are compatible with MSVC++:
937
e4e3cdc6 938Within the MSYS shell, build Libav with
c1989552
RP
939
940@example
9d361392 941./configure --enable-shared
c1989552
RP
942make
943make install
944@end example
945
946Your install path (@file{/usr/local/} by default) should now have the
947necessary DLL and LIB files under the @file{bin} directory.
d0e1cd3d 948
b8272cc2
MS
949Alternatively, build the libraries with a cross compiler, according to
950the instructions below in @ref{Cross compilation for Windows with Linux}.
951
c1989552
RP
952To use those files with MSVC++, do the same as you would do with
953the static libraries, as described above. But in Step 4,
954you should only need to add the directory where the LIB files are installed
955(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
bc3836a1
RP
956installed in the @file{bin} directory. And instead of adding the static
957libraries (@file{libxxx.a} files) you should add the MSVC import libraries
737eb597 958(@file{avcodec.lib}, @file{avformat.lib}, and
bc3836a1
RP
959@file{avutil.lib}). Note that you should not use the GCC import
960libraries (@file{libxxx.dll.a} files), as these will give you undefined
961reference errors. There should be no need for @file{libmingwex.a},
c1989552 962@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
a0db0b30 963statically linked into the DLLs.
c1989552 964
f8a45fa1 965Libav headers do not declare global data for Windows DLLs through the usual
e16c1569
RP
966dllexport/dllimport interface. Such data will be exported properly while
967building, but to use them in your MSVC++ code you will have to edit the
968appropriate headers and mark the data as dllimport. For example, in
969libavutil/pixdesc.h you should have:
970@example
971extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
972@end example
973
e971d813
MS
974Note that using import libraries created by dlltool requires
975the linker optimization option to be set to
a3a94e14 976"References: Keep Unreferenced Data (@code{/OPT:NOREF})", otherwise
e971d813
MS
977the resulting binaries will fail during runtime. This isn't
978required when using import libraries generated by lib.exe.

MS
979This issue is reported upstream at
980@url{http://sourceware.org/bugzilla/show_bug.cgi?id=12633}.
e971d813 981
37e6e6d3
MS
982To create import libraries that work with the @code{/OPT:REF} option
983(which is enabled by default in Release mode), follow these steps:
984
985@enumerate
986
987@item Open @file{Visual Studio 2005 Command Prompt}.
988
989Alternatively, in a normal command line prompt, call @file{vcvars32.bat}
990which sets up the environment variables for the Visual C++ tools
991(the standard location for this file is
992@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat}).
993
994@item Enter the @file{bin} directory where the created LIB and DLL files
995are stored.
996
997@item Generate new import libraries with @file{lib.exe}:
998
999@example
1000lib /machine:i386 /def:..\lib\avcodec-53.def /out:avcodec.lib
1001lib /machine:i386 /def:..\lib\avdevice-53.def /out:avdevice.lib
