emerge strangeness: failed emerges work on the second try

[spindle]

Have other people seen this? Over the last couple of months, I will fairly often get a compile error when emerging something (usually in a 'emerge -vuD world'), but if I just rerun the emerge command it will compile properly without a problem. This issue has happened with a lot of different packages for me.

Usually the error is a make error that says something like "no rule to make target xxx.cpp" but there have been different sorts of errors as well.

randome compile failure are simptom of hardware problems (mainly buggy RAM and overheat CPUs);
try to check the ram with memtest86, and check also the cpu temperature (now is summer and long compilation can make too hot the cpus)

Yeah, didn't even think of that. I'll bet it's the high CPU temp thing. I've been meaning to fix the dsdt on this box for a while anyway. That's probably it. Thanks !e.

I always recommend to use full copper heatsinks (orange metal, not grey or silver). And I mean full copper, not just aliminium with a small piece of copper). That can drastically reduce the temperature in athlon-xp processors, but will help in others as well.
