Works for me with gcc-4.1.1. What is your `emerge --info` and did you try recompiling everything it depends on with gcc-4.1?

build with gcc-4.1.1
:( compiler switched to gcc-3.4. So my last report was wrong. Error is still the same, even with gcc-4.1.1
-O3 seems to inline GuiHost<generalicon_c*>::chainiconstohost(generalicon_c*) in gui.o but that is also used outside, in building.cpp, so linker is not finding that. Maybe a gcc bug. Should we filter the -O3 then or wait for a fix to the compiler?
-O3 with gcc-4 replaced with -O2 in portage
(In reply to comment #6) > -O3 with gcc-4 replaced with -O2 in portage You said you had the same error with gcc-3.4?
(In reply to comment #7) > (In reply to comment #6) > > -O3 with gcc-4 replaced with -O2 in portage > > You said you had the same error with gcc-3.4? > No, I don't. Problem I saw is with gcc-4.1 and gcc-4.1.1. No problem with gcc-3.4.
So is this one fixed? I'm a bit confused.
(In reply to comment #9) > So is this one fixed? I'm a bit confused. > Bug is in the compiler, and my guess is that is still there. Workaround for asc is to change -O3 with -O2 when using gcc-4. This change is already in the ebuild. So, yes, for what regards games team, it is fixed.
Let's mark it as such, then.
The reason why I left it open is as a remind for a bug for gcc that need to be fixed. I assigned this to Gentoo Toolchain Maintainers <toolchain@gentoo.org> for exactly this reason. However I don't insist on let it open, as it seems nobody care of that bug :)
