[GRASS-dev] Re: [GRASS-user] GRASS 6.3 Installation Woes on OS X

[Michael Barton]

If you have a .grassrc6 file that has a set gisdbase, location, and/or
mapset (e.g., from using GRASS previously) and then you delete or rename any
of the above, GRASS init.sh will generate an error and GRASS will crash on
launch with the error message below.

The only fix is to either make the gisdbase, location, or mapset directory
that is listed in .grassrc6, or directly edit .grassrc6 to change or remove
the offending line.

Init.sh needs to trap this kind of error--or maybe better just ignore it. If
any of these files is not present, GRASS should simply go to either a) the
initial text based startup screen if the text interface or no interface is
selected in .grassrc6, or b) go to the GUI for selecting
gisdbase/location/mapset as if the gisdbase/location/mapset line was missing
from .grassrc6. In any case this should not cause a crash.
