Bug 91415 – pam-0.77-r6 fails to compile on emerge system during installation (gcc 4.0.0)

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Tiago Freire 2005-05-04 04:58:11 UTC]

I am installing a test system with GCC 4.0.0 to give it a try.
During 'emerge system',pam fails to compile:

Can confrim this for pam-0.77-r6 and pam-0.77-r8 on amd64
- switched gcc-config => x86_64-pc-linux-gnu-4.0.0
- emerge pam 
same story...

This problem disappears with pam-0.78, mainly the affected part has been rewritten...

[Comment 2 Tiago Freire 2005-05-04 07:00:33 UTC]

Unmasking pam-0.78-r2 compiled.
Since Gentoo does not oficially support GCC 4.0, this bug should be automagically fixed when the new pam ebuild is released...

[Comment 3 Diego Elio Pettenò (RETIRED) 2005-06-04 12:18:49 UTC]

GCC 4 on stable system won't be supported as it requires more fixes.
