Priority: criticalnormal

(Works fine here)

To make this a valid ticket, please add the configure line you tested, run make (it fails), run make again, then run "make V=1" and post the complete, uncut output of the last make call.

Ok, my configure is

./configure \
   --enable-nonfree \
   --enable-gpl \
   --disable-mmx \
   --enable-shared \
   --enable-version3 \
   --enable-runtime-cpudetect \
   --enable-hardcoded-tables \
   --enable-frei0r \
   --enable-libxvid \
   --enable-pic \

after performing the recommended commands, the output of make V=1 is

may be I should remove the whole tree and check it out again.
But today I don't have the time for that.
May be tomorrow.

(Unrelated to the actual ticket: Why are you using --disable-mmx ?)

comment:4 by Gero, 12 years ago

Why are you using --disable-mmx ?

Don't remember well.
When I started to use ffmpeg from source, I had some troubles, I could eliminate by usage of that switch. But I don't remember that kind of troubles.

Based on your question I removed that switch from my configure option-list and build works fine.
I'll test the usage of ffmpeg - may be I can live without it.

Thanks.

    x86: Fix linking with some or all of yasm, mmx, optimizations disabled
    
    Some optimized template functions reference optimized symbols, so they
    must be explicitly disabled when those symbols are unavailable.
