[FFmpeg-user] Error during the compilation of ffmpeg(libx264)

[Francesco Petronella]

Hi everyone. I'm trying to compile ffmpeg under Slackware 14.0 but during the compilation this error 
appears:



CC      ffmpeg.o
CC      cmdutils.o
CC      ffmpeg_opt.o
CC      ffmpeg_filter.o
LD      ffmpeg_g
libavcodec/libavcodec.so: undefined reference to `x264_encoder_open_128'
collect2: error: ld returned 1 exit status
make: *** [ffmpeg_g] Error 1x264 is correctly installed, before you ask to me.

I hope anyone can help me.

Thanks
