Bug 240538

Summary:	media-libs/gegl SSE/MMX autodetection bogus. Please add Flags.
Product:	Gentoo Linux	Reporter:	Sascha Hlusiak <bugs>
Component:	New packages	Assignee:	Hanno Böck <hanno>
Status:	RESOLVED FIXED
Severity:	normal

Attachments:	ebuild with USE="mmx sse"

Description Sascha Hlusiak 2008-10-08 15:35:22 UTC

On my athlon the sse/mmx autodetection detects that sse and mmx are both available, while only mxx is (sse isn't completely available). Compiling gegl results in illegal instructions in the gegl binary.

Please add USE Flags mmx and sse to the ebuild (passing --disable-sse, --disable-mmx to the configure script).

Thanks,
Sascha

Created attachment 167624 [details]
ebuild with USE="mmx sse"

using attached ebuild works for me.

Comment 2 Hanno Böck gentoo-dev

Thanks, fixed, but if these checks don't work you should probably report that upstream. Not a gentoo issue though, as we prefer not to autodetect anything.
