[GRASS-user] Wingrass 6.4 with MSYS does not work

[Daniel Victoria]

Hi Markus M.,

I forgot to mention that I'm using win7 and it's a Portuguese instalation...

I installed the Grass SVN version (tried bothe r42668 and r42681) and
I get the same problem in both. That is, when I try to launch
Grass64svn with MSYS console, after passing the select location
window, the MSys console just closes. Opening a separate MSys console
and executing /grass/bin/grass64svn will start the Select location
window and after I click on Start, Grass crashes with the following
error:

Welcome to GRASS 6.4.0svn (2010)
GRASS homepage:                          http://grass.osgeo.org/
This version running thru:               GNU Bash (Cygwin) (/usr/bin/bash.exe)
Help is available with the command:      g.manual -i
See the licence terms with:              g.version -c
If required, restart the GUI with:       g.gui wxpython
When ready to quit enter:                exit

Closing monitors ...
Cleaning up temporary files ...
Done.



Goodbye from GRASS GIS
