Using a cross-compiler is preferred for various reasons.
-@subsection DJGPP
-
-Libav cannot be compiled because of broken system headers, add
-@code{--extra-cflags=-U__STRICT_ANSI__} to the configure options as a
-workaround.
-
@section OS/2
For information about compiling Libav on OS/2 see
BSD make will not build Libav, you need to install and use GNU Make
(@file{gmake}).
-@subsubsection FreeBSD
-
-FreeBSD will not compile out-of-the-box due to broken system headers.
-Passing @code{--extra-cflags=-D__BSD_VISIBLE} to configure will work
-around the problem. This may have unexpected sideeffects, so use it at
-your own risk. If you care about FreeBSD, please make an attempt at
-getting the system headers fixed.
-
@subsection (Open)Solaris
GNU Make is required to build Libav, so you have to invoke (@file{gmake}),
Libav automatically passes @code{-fno-common} to the compiler to work around
a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
-Within the MSYS shell, configure and make with:
-
-@example
-./configure --enable-memalign-hack
-make
-make install
-@end example
-
-This will install @file{ffmpeg.exe} along with many other development files
-to @file{/usr/local}. You may specify another install path using the
-@code{--prefix} option in @file{configure}.
-
Notes:
@itemize
noticeable when running make for a second time (for example in
@code{make install}).
-@item In order to compile FFplay, you must have the MinGW development library
-of SDL. Get it from @url{http://www.libsdl.org}.
+@item In order to compile AVplay, you must have the MinGW development library
+of @uref{http://www.libsdl.org/, SDL}.
Edit the @file{bin/sdl-config} script so that it points to the correct prefix
where SDL was installed. Verify that @file{sdl-config} can be launched from
the MSYS command line.
This is how to create DLL and LIB files that are compatible with MSVC++:
-@enumerate
-
-@item Add a call to @file{vcvars32.bat} (which sets up the environment
-variables for the Visual C++ tools) as the first line of @file{msys.bat}.
-The standard location for @file{vcvars32.bat} is
-@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
-and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
-If this corresponds to your setup, add the following line as the first line
-of @file{msys.bat}:
-
-@example
-call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
-@end example
-
-Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
-and run @file{c:\msys\1.0\msys.bat} from there.
-
-@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
-from @file{Microsoft (R) Library Manager}, this means your environment
-variables are set up correctly, the @file{Microsoft (R) Library Manager}
-is on the path and will be used by Libav to create
-MSVC++-compatible import libraries.

-@item Build Libav with
+Within the MSYS shell, build Libav with
@example
-./configure --enable-shared --enable-memalign-hack
+./configure --enable-shared
make
make install
@end example
Your install path (@file{/usr/local/} by default) should now have the
necessary DLL and LIB files under the @file{bin} directory.
-@end enumerate
+Alternatively, build the libraries with a cross compiler, according to
+the instructions below in @ref{Cross compilation for Windows with Linux}.
To use those files with MSVC++, do the same as you would do with
the static libraries, as described above. But in Step 4,
libraries (@file{libxxx.dll.a} files), as these will give you undefined
reference errors. There should be no need for @file{libmingwex.a},
@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
-statically linked into the DLLs. The @file{bin} directory contains a bunch
-of DLL files, but the ones that are actually used to run your application
-are the ones with a major version number in their filenames
-(i.e. @file{avcodec-51.dll}).
+statically linked into the DLLs.
Libav headers do not declare global data for Windows DLLs through the usual
dllexport/dllimport interface. Such data will be exported properly while
Note that using import libraries created by dlltool requires
the linker optimization option to be set to
-"References: Keep Unreferenced Data (/OPT:NOREF)", otherwise
+"References: Keep Unreferenced Data (@code{/OPT:NOREF})", otherwise
the resulting binaries will fail during runtime. This isn't
required when using import libraries generated by lib.exe.
+This issue is reported upstream at
+@url{http://sourceware.org/bugzilla/show_bug.cgi?id=12633}.
+
+To create import libraries that work with the @code{/OPT:REF} option
+(which is enabled by default in Release mode), follow these steps:
+
+@enumerate
+
+@item Open @file{Visual Studio 2005 Command Prompt}.
+
+Alternatively, in a normal command line prompt, call @file{vcvars32.bat}
+which sets up the environment variables for the Visual C++ tools
+(the standard location for this file is
+@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat}).
+
+@item Enter the @file{bin} directory where the created LIB and DLL files
+are stored.
+
+@item Generate new import libraries with @file{lib.exe}:
+
+@example
+lib /machine:i386 /def:..\lib\avcodec-53.def /out:avcodec.lib
+lib /machine:i386 /def:..\lib\avdevice-53.def /out:avdevice.lib
