Bug 262190 – x11-libs/gtk+-2.14.7-r2: doesn't compile with "-Os" CFLAGS

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description ernsteiswuerfel 2009-03-11 20:02:51 UTC]

gtk+-2.14.7-r2 doesn't compile with "-Os" CFLAGS. As far I've tested all gtk+ versions above 2.14 exhibit this behaviour. This wasn'T the case with the 2.12 branch.

Workaround: Change gcc optimization level to "-O2", and gtk+ compiles again.

Reproducible: Always

Steps to Reproduce:
1. add -Os to your CFLAGS
2. emerge gtk+
3.

Actual Results:

Upstream (and therefore the gnome herd) doesn't support anything other than -O2.  We already strip -O3.

Gnome: should we strip -Os too?  Or maybe strip all -O and force -O2?

For gtk and glib, forcing -O2 sounds sensible.

It makes sense at least for the 2.14 branch.

2.12 seems fine with -Os and what 2.16 brings - who knows? ;)

[Comment 4 Gilles Dartiguelongue (RETIRED) 2009-03-12 10:00:14 UTC]

well looking at the error, it might not be related to -Os on gtk specifically. I would like to see more tests and an upstream bug if tests leads us to a real problem before considering blindly stripping -O level flags.

@reporter: please add emerge --info and full build.log.

ftr, I just tried building gtk+-2.14.7-r2 with -Os on my ~amd64 system I have not seen this problem. I'll close needinfo because we are missing comparison points.

gtk+ built with:
CFLAGS="-Os -march=native -ftree-vectorize -pipe -g" emerge -1Bav =gtk+-2.14.7-r2
