Bug 149210 – module-init-tools-3.2.2-r1 fails to compile with -combine in CFLAGS

• Product: Gentoo Linux
• Status: VERIFIED WORKSFORME

[Description Felix Leimbach 2006-09-26 12:02:56 UTC]

Compiling module-init-tools-3.2.2-r1 on AMD64 with
CFLAGS="-march=k8 -O2 -combine"
dies with the following error right after the configuring stage:
------
make[1]: Entering directory `/var/tmp/portage/module-init-tools-3.2.2-r1/work/modutils-2.4.27/util'

Compiling the same package with
CFLAGS="-march=k8 -O2"
completes just fine.

Thanks

So don't use it.

[Comment 2 Felix Leimbach 2006-09-26 13:23:34 UTC]

Ya I got that far, too :-)
Just wanted to point out that it is a canditate for filter-flags.
It would surely make the experience for gentoo users using this compiler flag smoother.

I for one decided to try it after reading a detailed post by Duncan about his choice of CFLAGS on the gentoo.amd64 newsgroup:
http://article.gmane.org/gmane.linux.gentoo.amd64/8924/match=gcc+4+1+upgrade+bad+desktop+interactivity+combine

Following this thread some more people decided to try it, as can be seen here:
http://article.gmane.org/gmane.linux.gentoo.amd64/9049/match=gcc4+1+upgrade+duncan+s+flags

Feel free to close the bug if you feel it's not worth it.
Thanks

Considering that bugzilla search returns exactly 3 bugs w/ emerge --info using this flag, I don't think this it worth filtering.

I think you'll get a few more now that Duncan has publicised the flag on [e-mail].

Before raising my bug 149300, of course I searched for bugs on module-init-tools but this one didn't show up. Sorry for the duplication.

Then go bug Duncan. ;)
