Description steffen stramm 2009-10-23 09:43:15 UTC

i get this when for example compiling zlib (being the smallest testcase i found).
also qdbus doesnt start when qt is compiled with this combination, cclive segfaults when parsing a youtube link and numerous other bugs.

if i downgrade to either gcc 4.4.1/binutils 2.20 or gcc 4.4.2/binutils 2.19
the problem is gone.
i encounter this on 2 machines, both ~amd64.

emerge --info from both of the machines attached

Could you attach the build.log from zlib?

funny, i emerged gcc 4.4.1 then 4.4.2 and binutils 2.20 again, now i can build zlib. however there are still warnings

I'd try a rebuild of world. Looks like some obscure bug, possibly because you've upgraded gcc from something really old?

When I rebuild world I usually use this formula, when I've already updated everything to the newest possible version:
emerge -eav --jobs=(cpus+sqrt(cpus)) --load-average=cpus --keep-going world
Where cpus is the number of cores in your machine and sqrt(cpus) is the square root of the number of cpus in your machine.
It will keep going and display a summary of failed packages at the end.

Comment 6 steffen stramm 2009-10-23 16:23:42 UTC

yeah, very obscure :p
i have a ~amd64 system for about 6 months, so nothing was old. thanks for the formula. :)
even if its solved i wonder if it happens to other people because it really causes all kind of bugs (like cclive just segfaulting without any mention to TEXTREL or something).
