[GRASS-user] Gui error behind splash screen

GRASS GRASS user
1

Hi all,

I just installed grass6.3 from les-ejk repository on a very striped
down ubuntu machine and I can create the location and mapset with no
problem in the GUI. The problem is that, after I create the mapset and
grass tries to load the gis.m it gives me an error message which I can
not see because it's behind the splash screen.

Could it be a tcl/tk version problem? I believe I have both 8.4 and
8.5. On the other hand, the location chooser gui works fine...

Thanks
Daniel

An update. Just found out that everything works fine with an UTM
location but, the failure happens when I try a lat-lon location.

Here is my wind file:
proj: 3
zone: 0
north: 7S
south: 15S
east: 57W
west: 67W
cols: 3704
rows: 2963
e-w resol: 0:00:09.719222
n-s resol: 0:00:09.719879
top: 1
bottom: 0
cols3: 1
rows3: 1
depths: 1
e-w resol3: 1
n-s resol3: 1
t-b resol: 1

Don't see anything wrong...

terminal but g.region -p gives me a segmentation fault

Another GRASS+Ubuntu segfault. Use search to get more info. In short:
remove GRASS and all of it's dependencies and complie new ones FROM
SOURCE! (or choose some better user-friendly distribution like Gentoo)

Sorry for breaking-in to your discussion.

I want to confirm that through my small experience with Ubuntu and
osgeo-tools, I have seen several times segfault problems. Things are
really better when compiling from source.

About the "Gentoo and user-friendly" argument: it could use a ";-)"
smiley :-).

FWIW:
Seriously, I don't doubt about it being *real user-friendly*. But most
people tend to identify user-friendly systems as systems that just work
out-of-box. Since there are different views it is necessary to define
what one understands as *user-friendly* and what not. Anyhow, I think
that Gentoo, is definitely NOT for a new-comer in the FOSS4G field.

Kind Regards, Nikos

I was hopping I would not have to resort to compiling everything from
source. I recall that a while ago a simple apt-get would be enough to
get everything working just fine in Ubuntu. Now that was friendly...

ok, next we need to figure out why.

can you rerun with:
g.gisenv set="DEBUG=5"

so it might say how far it got. (set back to 0 to turn off debug messages)

and then post a backtrace from gdb:

Can't do that right now because I removed everything and I'm now
trying to compile everything from source. Unfortunately, my computer
is very slow and it takes almost 4 hours just to compile GDAL. Grass
takes another 5 hours...

If I'm not sucessful compiling I'll try the Ubuntu repos again and
then will do the gdb thingy

Finally, everything is working. It turned out to be a mix up of gdal
libraries and gdal-grass plugin installed from the ubuntu
repositories.

Solved everything by clearing all gdal related instalation and
compiling gdal and grass from source.

Now apparently everything is working and I've seen the wxPython GUI
for the first time! Impressive!! Congrats all grass developers for the
well done job
