Bug 62796 – xorg-x11 doesn't build with -fstack-protector

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description meyerm 2004-09-04 02:23:36 UTC]

Using gcc-3.4.1 and xorg-x11-6.7.0-r2 the compile fails with -fstack-protector. I didn't find any previous bug report like this (there are too many or zero hits ;-) ), BUT in the ebuild there is a 

ALLOWED_FLAGS="-fstack-protector ...."

which is certainly a problem

Reproducible: Always
Steps to Reproduce:
1. ACCEPT_KEYWORDS=~x86
2. CFLAGS=.... -fstack-protector ....
3. emerge xorg-x11

Actual Results:  
libbitmap.a complains about the symbols (stack_guard and so, that's why I 
tried using no stack-protector even though it is explicit allowed in the 
ebuild). 

Expected Results:  
Without it works (slow as hell, but that's surely another problem with the new 
KDE... ;-) )
