[GRASS-user] Need help identifying missing wxgtk dependencies

HI,

I’m doing a fresh install of Grass 8.3dev on a new laptop running Linux Mint 20.3. It’s been a while since I’ve had to do a new install, so used the Linux Mint wiki instructions here: https://grasswiki.osgeo.org/wiki/Compile_and_Install#Linux_Mint

I had no obvious error during configure/make/install.

g.version -gre
version=8.3.dev
date=2022
revision=c1b1ff69d
build_date=2022-08-11
build_platform=x86_64-pc-linux-gnu
build_off_t_size=8
libgis_revision=2b85ab5eb
libgis_date=2022-07-25T15:37:35+00:00
proj=7.2.1
gdal=3.5.1
geos=3.11.0
sqlite=3.31.1

After launching Grass, g.region -p gives:

g.region -p
projection: 99 (unnamed)
zone: 0
datum: wgs84
ellipsoid: wgs84
north: 149300
south: 124200
west: -25900
east: 7800
nsres: 100
ewres: 100
rows: 251
cols: 337
cells: 84587
free(): invalid pointer
Aborted (core dumped)

Launching g.gui gives a popup window that says “Unable to get geographic extent. Force quitting wxGUI. Please manually run g.region to fix the problem.”

On the terminal, this was printed after launhcing g.gui:

g.gui
Launching GUI in the background, please wait…
wxdigit.py: Could not load grass_gis.8.3.
wxnviz.py: Could not load grass_gis.8.3.

I noticed in the wxGUI console these messages:

"3D view mode not available
Reason: cannot import name ‘DM_FLAT’ from ‘nviz.wxnviz’ "

and also this one:

“Vector digitizer not available.
Reason: name ‘sys’ is not defined”.

I thought I had all python/wxwidgets dependcies satisfied, but I must be missing something obvious??

Additionally, I wanted to ask if we have a searchable​ Grass mailing list site? The mailman site is kind of useless for trying to search old messages.

Thanks for any clues!

Please check if you have by chance PROJ libraries twice on your system
(maybe a leftover from a local compilation vs distro packages.

sudo updatedb
locate libproj

may be of help here. Also check the output of

ldd $(which g.region)

for anything suspicious.

Launching g.gui gives a popup window that says "Unable to get geographic extent. Force quitting wxGUI. Please manually run g.region to fix the problem."

On the terminal, this was printed after launhcing g.gui:

> g.gui
Launching <wxpython> GUI in the background, please wait...
wxdigit.py: Could not load grass_gis.8.3.
wxnviz.py: Could not load grass_gis.8.3.

Please check (with locate, see above) if the library is on your system.

I noticed in the wxGUI console these messages:

"3D view mode not available
Reason: cannot import name 'DM_FLAT' from 'nviz.wxnviz' "

and also this one:

"Vector digitizer not available.

Mhh, weird. Maybe an error caused by another error?

I want that, too :slight_smile:

Hi Markus,

Indeed, it looks like a did have multiple projlibs installed - thanks.

I still seem to have the wxdigit error, though.

wxdigit.py:

locate wxdigit.py

/usr/local/grass/dist.x86_64-pc-linux-gnu/gui/wxpython/vdigit/wxdigit.py
/usr/local/grass/gui/wxpython/vdigit/wxdigit.py
/usr/local/grass83/gui/wxpython/vdigit/wxdigit.py

wxnviz.py:

locate wxdigit.py

/usr/local/grass/dist.x86_64-pc-linux-gnu/gui/wxpython/vdigit/wxdigit.py
/usr/local/grass/gui/wxpython/vdigit/wxdigit.py
/usr/local/grass83/gui/wxpython/vdigit/wxdigit.py

Thanks so much for this site, I had no idea it existed!

And libgrass_gis.8.3.so etc are existing?

I still seem to have the wxdigit error, though.

wxnviz.py:

/usr/local/grass/gui/wxpython/vdigit/wxdigit.py
/usr/local/grass83/gui/wxpython/vdigit/wxdigit.py

Pls run this to print the Python and wxPython versions:

python3 -c "import sys, wx; print(sys.version); print(wx.version())"

I would say ctypes compilation may be a problem, there is a common issue related to libproj, see also https://github.com/OSGeo/grass/issues/435#issuecomment-688807074

Thanks for the link, Anna. I have the multiple proj installations thing resolved now, but I’m not sure what to make of the ctypes issue. I read through the bug report, but it’s beyond me.

Does the ctypes part of compilation go through ok? It seems to me the problem you describe is not related to Python or wx.

I don't see anything related to ctypes in the configuration messages or the config.log - what config messages should a "good" installation have?
