can't emerge xorg-x11

[carbuncofeliz]

I'm not able to emerge xorg-x11:

emerge xorg-x11

I get
s_tritemp.h: In function `flat_ci_triangle':
s_tritemp.h:1298: internal compiler error: Illegal instruction

The bug is not reproducible, so it is likely a hardware or OS problem.

I've done a four days memtest without getting any errors so I guess the RAM is OK.

Any idea??

TIA.

How much RAM do you have? Do you have swap enabled? Do you have headers for a 2.6.11 kernel and source for a 2.6.16 kernel?

[carbuncofeliz]

I've 512MB of RAM, the swap is enabled, my kernel is a 2.6.16 but I don't know what headers you mean. May they be the linux-headers?? if they are, they're already installed.
I've got no idea what to do...I've tried lots of things but nothing seems to work.

TIA.

Signal 11 (http://www.bitwizard.nl/sig11/) the former tells all the possible reasons for a Signal 11. If your RAM has two modules, take one out, start the xorg compilation again, see if it crashes at the same place. Then try the other RAM module by itself., if it does the crash at the same place it is a compiler problem.
See the entry about memtest at the bottom of the listed article.
As far as headers go, I was talking about kernel headers. "Kernel-headers includes the C header files for the Linux kernel. The header files define structures and constants that are needed for building most standard programs. The header files are also needed for rebuilding the kernel."
I noticed on the output in the second window it said "virtual/os-headers: 2.6.11-r2" and I did not know if that was reflecting the version of the kernel headers you have installed or if it was something else.

[mrrangerman43]

Do you have your CFLAGS and CXXFLAGS setup right? They would be in # nano -w /mnt/gentoo/etc/make.conf look here http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?full=1#installing_portage

[carbuncofeliz]

I've got only one module of RAM but I've tried with other modules as you suggest.
The signal 11 looks interesting I was told that maybe the speed of the RAM is the problem but...as I've already said a 4-days memtest reported 0 errors (?)

I'm not quite sure if I understand you about the headers, I come from debian where I know there's a package called kernel-headers-xxx but in gentoo emerge --search kernel-headers gives 0 matches.

Finally, my CFLAGS and CXXFLAGS have been changed so many times that I'm not sure If they are correct or not; but I'd bet they aren't the solution (an infimun bet it's understood)

Thanks a lot!

Is this a new install?
It looks like hardware error to me....

[carbuncofeliz]

Indeed, it's a new installation. I agree with you: it's probably a hardware error.
I tried to drop the speed of the RAM but either the computer doesn't start or the emerge command gives a similar error.

PS. I was able to install gentoo on my ibook G4 quite easily...this situation is getting funny, isn't it?

TIA.
