Hi everybody, I am trying to compile ffmpeg on debian squeeze using this
guide https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu.

Unfortunately when I make ffmpeg i get this error.

How can I fix it?

libavfilter/vf_subtitles.c: In function 'config_input':

libavfilter/vf_subtitles.c:146: error: implicit declaration of function

libavfilter/vf_subtitles.c: At top level:

libavfilter/vf_subtitles.c:215: error: 'ASS_SHAPING_SIMPLE' undeclared here
(not in a function)

libavfilter/vf_subtitles.c:216: error: 'ASS_SHAPING_COMPLEX' undeclared
here (not in a function)

make: *** [libavfilter/vf_subtitles.o] Error 1
