[Ffmpeg-devel] [patch] apple-intel shared library compile fix

[Tom Harper]

Hi,

So compiling shared libraries on intel-apple is currently broken in svn.
Following is the build info/compiler error (just fyi):

cc -dynamiclib -Wl,-single_module 
-Wl,-install_name,/usr/local/lib/libavcodec.dylib,-current_version,51.1.0,-compatibility_version,51.1.0 
-Wl,-dynamic,-search_paths_first  -o libavcodec.51.dylib bitstream.o 
utils.o allcodecs.o mpegvideo.o jrevdct.o jfdctfst.o jfdctint.o
