Compiling source code on FAI client

[dominik baenninger]

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.
