[GRASS-user] GRASS 6.4.RC3 GUI not starting on windows & GRASS 7 not launching at all

Hanan_Karam · May 13, 2013, 11:29am

Hi everyone,

I downloaded the Windows binary for Grass 6.4.3RC3 (dated April 20, 2013, available on http://grass.osgeo.org/grass64/binary/mswindows/native/) and installed it on my Windows PC (6-4 bit, running Windows 7).

I got the following error message on start-up.

Starting GRASS …

Error in GUI startup. If necessary, please

report this error to the GRASS developers.

Switching to text mode now.

Hit RETURN to continue…

I also tried with the most recent WinGRASS binary snapshot: 6.4.3svn-r56225, and got the same result.

I also tried download and installing the most recent binary snapshot of winGRASS 7: r56229, and that wouldn’t start at all.

I have winGRASS 6.4.3 RC2 working fine on my PC. A previous binary snapshot of winGRASS 7 (about a month old) was also working fine, but I uninstalled it to install the most recent version.

I appreciate any ideas you have on what might be going wrong.

Thank you,

Hanan

I had the same problem and found out that a system-wide Python
installation (2.7.2, independent of GRASS) caused the trouble.
Uninstalling the system-wide python helped, but this may not be an
option for many users, because other software might rely on a
particular python version installed.

I just want to confirm that replacing my system-wide Python installation with version 2.7.4, instead of 2.7.2, solved the problem.

Thank you very much

thanks for the confirmation.
(@devs: where to put wingrass release notes these days?)

Uninstalling the system-wide python helped, but this may not

for them the GRASS python.exe can be set with full path name in
C:\Program Files\GRASS GIS...\etc\env.bat:

set GRASS_PYTHON=%GISBASE%\extrabin\python.exe

Not exactly user-friendly, but simple enough once you know
what to do. any reason not to make the full path the default?
