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?

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. Thank you very much for the help, David David Peterson -------------------------------------------- ~Dovie'andi Se Tovya Sagain~ Sandia National Laboratories Org. 1555 Computational Structural Mechanics & Applications P.O.

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.
