Bug 342319 – Compilation of x11-libs/cairo-1.10.0-r3 failed

• Status: RESOLVED FIXED
• Product: Gentoo/Alt

[Description Konstantin Tokarev 2010-10-23 14:20:06 UTC]

Compilation of x11-libs/cairo-1.10.0-r3 failed on OS X beacuse of missing symbols ___umodti3, ___udivti3, and ___multi3

[Comment 1 Fabian Groffen 2010-10-23 14:21:52 UTC]

please try the following:
- if you have -O2, replace it with -O3
- if you have -mtune/-mcpu flags, drop them
- if you have other flags, drop them in isolation

[Comment 3 Konstantin Tokarev 2010-10-23 16:00:45 UTC]

It helped, thanks! However, previous version cairo-1.8.10 build fine with my CFLAGS (-O2 -pipe -mcpu=G5 -mtune=G5)

[Comment 4 Fabian Groffen 2010-10-23 16:04:55 UTC]

which combination helped?  switching to -O3?

[Comment 5 Konstantin Tokarev 2010-10-23 16:11:01 UTC]

Hm.. I've thought you mean to these all at once :)
I've succeeded with CFLAGS="-O3" (without any march or mtune)
-O3 with -march=G5 and -mtune=G5 failed compiler test

[Comment 6 Konstantin Tokarev 2010-10-23 16:12:22 UTC]

CFLAGS="-O3 -pipe -mtune=G5"  works fine

[Comment 7 Konstantin Tokarev 2010-10-24 12:35:59 UTC]

I've made a mistake - used -march instead of -mcpu. However, CFLAGS="-O3 -pipe -mcpu=G5 -mtune=G5" fails with the same error as was originally reported

CFLAGS="-O3 -pipe -maltivec -mtune=G5" - works
CFLAGS="-O3 -pipe -mpowerpc-gpopt -mtune=G5" - works
CFLAGS="-O3 -pipe -mpowerpc-gfxopt -mtune=G5" - works
CFLAGS="-O3 -pipe -mmfcrf -mtune=G5" - works
CFLAGS="-O3 -pipe -mstring -mtune=G5"  - works
CFLAGS="-O3 -pipe -mmultiple -mtune=G5" - works

I don't know what else may be enabled by mcpu=G5

[Comment 8 Fabian Groffen 2010-10-24 20:07:34 UTC]

I filtered -mcpu in the ebuild
