Hi Carl, Thanks for the reply. I would be happy to act on any explanations it gives but there was no explanation I saw. This is most likely due to my ignorance. Excerpts from the .log files from configure attached (these are the last 4 of 11 times it hit). Do this make any sense to you perhaps why it would be thus throwing the error? gcc -L /ffmpeg_installation/ffmpeg_build/lib -Wl,--as-needed -Wl,-z,noexecstack -static -o /tmp/ffconf.xsWlVzny/test /tmp/ffconf.xsWlVzny/test.o -lbz2 -pthread -pthread /usr/bin/ld: cannot find -lbz2 collect2: error: ld returned 1 exit status gcc -L /ffmpeg_installation/ffmpeg_build/lib -Wl,--as-needed -Wl,-z,noexecstack -static -o /tmp/ffconf.xsWlVzny/test /tmp/ffconf.xsWlVzny/test.o -llzma -pthread -pthread /usr/bin/ld: cannot find -llzma collect2: error: ld returned 1 exit status ffmpeg_installation/ffmpeg_build/lib/libx264.a(mc-c.o): In function `x264_plane_copy_avx':mc-c.c:(.text+0x11ac): undefined reference to `_intel_fast_memcpy' collect2: error: ld returned 1 exit status ffmpeg_installation/ffmpeg_build/lib/libx264.a(mc-c.o): In function `x264_plane_copy_avx':mc-c.c:(.text+0x11ac): undefined reference to `_intel_fast_memcpy' collect2: error: ld returned 1 exit status ERROR: libx264 not found As for yasm and nasm. It was a while back but it griped unless I had both. The compilation guide instructs to install both as well for RHEL. Again, am very green to any compiling under unix based systems to please forgive my ignorance.

I can see from the config.out that it knows where libx264.a is at but it always dies and says:
collect2: error: ld returned 1 exit status ERROR: libx264 not found
I am quite sure the configure script gave you useful explanations what you should do - why do you ignore them? I at least would like to know what collect2 was unhappy about, or actually: I need it to be able to answer your question.
rm -rf $FFMPEGDIR/ffmpeg_sources/yasm rm -rf $FFMPEGDIR/ffmpeg_sources/nasm-2.13.01
Unrelated: You need either yasm or nasm, yasm does not support AVX-512 (which so far you don't want to use). You cannot use both.
