@ -970,6 +970,34 @@ 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
lib /machine:i386 /def:..\lib\avfilter-2.def /out:avfilter.lib
lib /machine:i386 /def:..\lib\avformat-53.def /out:avformat.lib
lib /machine:i386 /def:..\lib\avutil-51.def /out:avutil.lib
lib /machine:i386 /def:..\lib\swscale-2.def /out:swscale.lib
@end example
@end enumerate
