Bug 25870 – mjpegtools filters -march=pentium4 without filtering -mfpmath=sse, causing a warning, upgraded to an error by -Werror

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Zhen Lin 2003-08-04 07:04:17 UTC]

In mjpegtools, -march=pentium4 is filtered into -march=i686, without filtering
-mfpmath=sse, causing a warning, once per compile. The package-defined CFLAGS
include -Werror, upgrading this warning into an error, causing the compile to fail.

Reproducible: Always

New mjpegtools-1.6.0 ebuild filtering -mfpmath=sse

One line fix:
filter-flags="-mfpmath=sse"

Fixed mjpegtools 1.6.1 too.. Same one line fix:
filter-flags="-mfpmath=sse"

fixed in cvs

Having issues with another flag (-fprefetch-loop-arrays). The ebuild fails without filtering it out. If the original poster (or the admins) will kindly reopen this bug (or fix it in cvs), that would be great.

My fix is to use:

filter-flags "-mfpmath=sse -fprefetch-loop-arrays"

Forgot to say this was with media-video/mjpegtools-1.6.1.90
