[Scratchbox-users] Scratchbox2 setup problem

[Jan Dohl]

Hello again,

I knew it was something stupid, but this exceeds expectations. After 
digging through some of the more detailed logfiles and parts of the code 
it became apparent that the execution of "qemu-arm" failed with error 2 
(No such file or directory). So just for the heck of it I changed (in 
sb2.config of my target)

export SBOX_CPUTRANSPARENCY_METHOD="qemu-arm"

to

export SBOX_CPUTRANSPARENCY_METHOD="/usr/bin/qemu-arm"

to make sure it gets found. This fixes the problem for me. I don't 
really know why this happens as /usr/bin is in my $PATH, but if anyone 
faces the same problem this might help. Maybe I'll dig a bit more 
through the code if I find the time.

Greetings
Jan
