Bug 164689 – gcc 4.1.1 and -fstack-protector-all does not work

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Michal Suchanek 2007-01-31 11:07:22 UTC]

Tried to configure wine 0.9.22 with gcc 4.1.1-r2 and added flag -fstack-protector-all.

I get error in configure that says compiler cannot create executables. The config log says something about missing symbols.

It does not fail in configure with just -fstack-protector

Reproducible: Didn't try

Steps to Reproduce:
1. switch to gcc 4.1.1
2. add -fstack-protector-all after the strip-flags in wine ebuild
3. emerge wine

Actual Results:  
compilr fails to create executables

Expected Results:  
builds

Portage 2.1.1-r2 (hardened/x86/2.6, gcc-3.4.6, glibc-2.3.6-r5, 2.6.17-gentoo-r4 i686)

So don't do it... gcc-4* is masked on hardened profiles and this flag is not supported anyway.
