When I compile gsm,it appears such error:
rm: cannot remove './lib/libgsm.a': NO such file or dierctory
make: [lib/libgsm.a] Error 1 (ignored)
./lib/libgsm.a: line 1: syntax error near unexpected token 'newline'
./lib/libgsm.a: line 1: '!<arch>'
make: ***[lib/libgsm.a] Error 2
But there is libgsm.a in ./lib directory,so I donnot modify the gsm but continue to make ffmpeg.
When I execute the 'make' command in the ffmpeg directory, it appears the following errors:
1. libswscale/swscale.c :140: error: conflicting types for 'ff_dither4'
libswscale/swscale_internal.h:447: error: previous declaration of 'ff_dither4' as here
