Re: [E-devel] evas mmx issues
Actually, this is probably a bug. What signal did this die from? A illegal instruction or a segv? (Sorry, deleted the original message w/o reading it closely enough).

Well, my processor does support mmx, so I don't see any reason why it should do this. Unless there's some extra configure option to only enable mmx and not mmx2 that I'm missing. Also, the crash only happens when im running entrance and it would seem that by doing so, a bug in entrance or evas is making evas think that i have an mmx2 capable processor. By the way the crash results from an illegal instruction. --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
