Thanks for your help. Totally my fault. I cloned blindly from the ffmpeg git repository on github, rather than from ffmpeg.org <http://ffmpeg.org/>. I think I just typed “ffmpeg git” in google and went for the first link in the list. Compiling now from the ffmpeg.org <http://ffmpeg.org/> repository and it seems to work (at least it has not stopped compiling yet).
