[FFmpeg-user] Build LGPL version of FFmpeg for Windows

[Michael Raab]

Hi,

the hint helped, but I'm still struggeling. I'm trying to compile with 
msvc. Therefore I followed the guide at:
http://blogs.gnome.org/rbultje/2012/09/27/microsoft-visual-studio-support-in-ffmpeg-and-libav/

When trying to configure, I get the following error:
$ ./configure --toolchain=msvc
c99wrap cl is unable to create an executable file.
If c99wrap cl is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.

Any Ideas?

Thanks,
Michael

Completely unrelated to your problem:
--enable-swscale --enable-avfilter and --disable-libopenjpeg 
are unneeded (all three are default), --enable-version3 does 
not have any effect afaict.

(After reading your email address, I even suspect you really, 
really don't want to use --enable-version3.)

And I wonder if --enable-memalign-hack is really needed, I 
honestly don't know.
