[FFmpeg-devel] Cross Compiling.

[Marcus Johnson]

I'm on OS X 10.9.2 with clang from Xcode 5.0.2, and trying to cross compile
ffmpeg for Windows, everything works fine so long as it's built statically,
when I try building it with --disable-static --enable-shared I get the
following error message:

My configure options are: ./configure --disable-yasm --enable-cross-compile
--target-os=win32 --arch=x86_64 --disable-static --enable-shared
--enable-opencl

At first I thought the error was due to opencl being enabled, so I ran it
again without enabling opencl and it gave the exact same error message,
also I disabled yasm because I was to lazy to download and install it, but
I really doubt that is the problem.
