Any idea? The problem is that one of the variables (libpath, isislibpath, isis3rdparty) is None, and "None + str" isn't defined: > None + "hello" Traceback (most recent call last): File "", line 1, in TypeError: unsupported operand type(s) for +: 'NoneType' and 'str' -- Glynn Clements ___ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev

Hi Vaclav, on my 64 bit machine, none of this happens. Will check back home tonight...

I would say that one of libpath, isislibpath and isis3rdparty is None although lines above seems that they sets everything. Can you debug your code? Simple print before line 753 should be enough: print libpath, isislibpath, isis3rdparty As far as I know, the print will not break the start up, so it should work.
