It seems USE=-mmx solved this issue. Just like Bug 62489

have you tried with -march _instead of_ -mcpu?

Comment 5 Ole Tange 2004-09-17 19:18:29 UTC

Yes. That works, too. However, mmx is not a default Gentoo setting, whereas mcpu _is_. In my opinion it would be unreasonable to assume a Gentoo user should change a default setting just to make something compile.

depend -> same reporter

Comment 7 Ole Tange 2004-09-25 10:03:30 UTC

I had a gut feeling that this was caused by USE=hardened. So I tried removing
'hardened' and recompiled first gcc then ogle-gui. It works. I thereby feel
that it is proven that it is the 'hardened' version of gcc that conflicts with
ogle-gui.

You can blame hardened if you want.
USE=-mmx or -fomit-frame-pointer or misc levels of -O[0-3,s] all effect the 
number of free registers on the x86 arch. so pick something mmx/pic/-fomit.. or 
other to free up some regs.

ogle-0.9.2 emerges fine here with mmx enabled; I think because the file is now
compiled with the '-fomit-frame-pointer', which regains a register (something
from the ogle build, not from my CFLAGS).

Please try the latest version, and re-open if problem is not fixed for you.
