Hi List,

For the last few weeks i was playing around with my newly acquired
raspberry pi 2. While it was pretty easy to setup a working gentoo
stage3 system i failed installing anything below the basic packages.
Generally my idea was building the arm packages on any system and
provide them as binary packages for other raspberry pi's (yeah, i
already bought my second rpi :D)

At first, my idea was to build all the packages directly on the rpi. (with
/var/tmp & /usr/portage on a external harddisk). However, the compile
times are worse than i expected so i abandoned the idea.

Next i've played around with crossdev. It sort of worked, but i never
could finish compiling xorg-server. (or basic system packages) Even
though i've started over and over with different settings, there were
always packages which failed to compile thus doesn't let me finish
xorg-server. I might look into it some other day but now i just wanted
something working.

Now i'm playing with using qemu-arm [1][2] in order to compile the
packages inside a chroot. This is - so far - the most promising method
building packages, even though the compile times are worse than with
crossdev, but still better than directly on the rpi.

So far i finally could compile xorg-server and also updated the whole
system, which, at this point, wasn't much anyway. My next goal was kde.
I've compiled about half of all packages which are required for
kdebase-meta, but now i'm stuck at kdelibs and i have no idea what's
wrong.

The problem:

The problem is, the compile doesn't fail - it just hangs/stops. At some
point (which seems to be random - it can stop anywhere between 1% and
100% of the compile) the compile stops and does nothing. I've waited
hours, but nothing happened.
So far i tried lots of things, for example:
* MAKEOPTS="-j1" and/or FEATURES="-sandbox"
* also tried without building binary packages (-buildpkg)
* /var/tmp on tmpfs
* using: ebuild /usr/portage/kde-base/..../kdelibs....ebuild compile
* using python3.3 instead of default 2.7
* moved it on a different system and tried building it there (again with
many different settings)

Nothing worked, even though the build moved until 100% two times (-_-)

I have no idea what the problem is. Even qtwebkit, which took way longer
to compile (about 3 hours) compiled on the first try. (which should
exclude temperate and/or resource problems)
I also don't think it's a problem with a use flag as the build stops
anywhere - i couldn't find a pattern. It seems to be completely random.

Any ideas whats wrong or how to fix this? Any help would be much
appreciated as i'm out of ideas :(

Thx
