Hello,
i had to update my kernel due to hardware.
As new kernels are compiled with gcc 5.1 i also updated it.
Since then i can not compile workstation kernel modules.
Everything else works es expected and i can compile other packages with gcc 5.1.
This is the only log message i get from workstation is:
2015-06-27T12:02:26.071+01:00| vthread-3| I120: Found compiler at "/usr/bin/gcc"
2015-06-27T12:02:26.078+01:00| vthread-3| I120: Got gcc version "5".
