problem starting r.mapcalc from the wxGUI command prompt

[malicera]

When I try to run an operation in r.mapcalc it fails.

I think there is a wrong path somewhere in the RC3, because it look for some "C:/osgeo4w/..." which is not in my system.

In my computere I have also Qgis with grass 6.4.2RC2 which has no problem with this operation.

The message in the command console is:

Settings: unable to get value 'workspace:posManager:enabled' Settings: unable to get value 'workspace:posDisplay:enabled' Traceback (most recent call last):

Please could you try recent version from SVN (pre-build binaries available at (1)). This bug has been recently fixed (r50212).

it's unrelated. The path points to the real path when compiling python files

The message in the command console is:

please next time consider to use preformatted text

output...
