Thanks for your tip, but I still have some difficulties. When I proceed
as you described, the code will be compiled, but the output file will be
written to root directory. So, I have to change the directory for
compilation. I thought that something like
$ROOTCMD cd /home/cluster/clustersoft
$ROOTCMD gcc /home/cluster/clustersoft/test.c
resp.
$ROOTCMD cd /home/cluster/clustersoft
$ROOTCMD gcc test.c
should work, but obviously, it does not :( Any help is apreciated.

From previous runs I learned that I have to put the keyword "$target"
infront of the gcc command and in front of the file I would like to compile
(test.c). But know, fai complains that the file stdio.h (this is file which
I include in test.c) can not be found. Obviously, I should also add the
keyword "$target" infront of any filename I call within the source-code,
but this would not make any sense ...

Ok, just one seeming misconception: $target is not a keyword, but a simple
environment variable (ah, and you should be using $FAI_ROOT, IMHO); but the
solution should be pretty simple: State line 5 as
$ROOTCMD gcc /home/cluster/clustersoft/test.c
as $ROOTCMD expands to "chroot $FAI_ROOT", which is what you need: a chroot.
Best,
Michael
