[Ffmpeg-devel] compilation error in mathematics.c

[carboncopy public]

I compile on Mac and I add in -DHAVE_LRINTF into my --extra-cflags, viz:

--extra-cflags="-DHAVE_LRINTF"

This is pass to the configure, viz :

./configure --extra-clags="-DHAVE_LRINTF"

Of course they are other flags which you might want to incorporate in
there. Just seprate the flags with a space and insert it where
appropriate, viz (mine):

--extra-cflags="-fast -I/opt/local/include -DHAVE_LRINTF -ftree-vectorize"
