Re: [GRASS-user] 7.9.dev: which wxPython versions supprted?

[Maris Nartiss]

tl;dr Only master branch (7.9) has some wxPython-4.1 related fixes.
Unless you are ready to provide fixes, do not mix GRASS with wxPython
>4.0.

After upgrading to proj-7 you forgot to recompile all libraries
linking to proj. If you are running a system with pre-built packages,
go bark on your GIS package maintainer.
Be ware — mixing proj 6 and 7 in a single system is a road to failure.

From nete...@osgeo.org Mon May 25 14:35:42 2020


Rich,

did you see
https://github.com/OSGeo/grass/issues/649
?

To which I responded,


Nope. I'll grab wxPython-4.1.0 and see if it builds with the SBo script.


Here's the latest;

I'm moving this to the user mail list because I'm not subscribed to the dev
mail list.

I downloaded wxPython-7.1.0 source code, changed the version number in the
SlackBuilds.org (SBo) build script, and the build completed without errors
other than a couple of empty metadata files.

However, when I try to start 'grass79 -gui' it fails with these errors:

$ grass79 -gui

Is this a grass issue or an SBo issue? If the latter I'll let the package
maintainer know and he'll probably have it fixed tomorrow.

Well, now I'm thoroughly confused. The PDAL web landing page says they've
released version 2.1.0. Perhaps the proj adoption page refers to PDL, the
Program Design Language and not PDAL?

Grass 7.9.dev source code, when configured, reports it's using new PROJ 5+
API, but the web page on who's using which proj header file says that grass
has adopted proj.h which is the most recent since project.h was dropped with
proj6 and proj-api.h was supposed to be dropped with proj7.

When I run 'make' it eventually fails because,
v.in.pdal: error while loading shared libraries: libproj.so.15: cannot open
shared object file: No such file or directory

That's because proj-7.0.1 provides libproj.so.19.

Please help me understand.

Rich

[GRASS-user] 7.9.dev: which wxPython versions supprted?

[Rich Shepard]

On my Slackware-14.2/x86_64 systems wxPython4-4.0.7.post2 is installed. When
I try to start grass79 -gui it fails with this error:
Starting GRASS GIS...
ERROR: wxGUI requires wxPython. No module named 'wx'
You can still use GRASS GIS modules in the command line or in Python.

In ~/.bash_profile I

What wxPython version do I need to use with 7.9.svn?

[GRASS-user] Status of pdal-2.1 support?

I understand that work's in progress to support pdal-2.1 and higher in the
development branch, and I'm curious if there's an estimated date when it
might be available.

^--- and chance to expand this "truncated"? Exactly therein you will
find the error message :-)
It is in the last line of the truncated part.

Re: [GRASS-user] Error in v.distance when running from R (in a container)

[Mehrdad Varedi]

Hi Everyone,
I can run the R program with no problem from a Shiny app I have in Rstudio.
Although when running the program from a container, I receive an error when
running the v.distance and program halts.

here is the error dump I receive, not so much informative, although I
appreciate to know if you have ever seen such an issue: (FYI many other
grass functions are executed before this error happens)

Warning: Error in execGRASS: The command:
v.distance --overwrite --verbose from=WM_End from_layer=1 from_type=point
to=WM_start to_layer=1 to_type=point dmax=0.5 dmin=-1 upload=to_attr
column=LinkedWMID to_column=WMAINID separator=tab
produced an error (1) during execution:
Finds the nearest element in vector map 'to' for elements in vector map
'from'.

Usage:
 v.distance [-pas] from=name [from_layer=string]
   [from_type=string[,string,...]] to=name [to_layer=string]
   [to_type=string[,string,...]] [output=name] [dmax=value] [dmin=value]
   upload=string[,string,...] [column=name[,name,...]] [to_column=name]
   [table=name] [separator=character] [--overwrite] [--help] [--verbose]
   [--quiet] [--ui]

Flags:
  -p   Print output to stdout, don't update attribute table
  -a   Calculate distances to all features within the threshold
  -s   Print output as square matrix (only possible for one single upload
variable)

Parameters:
from   Name of existing vector map (from)
  from_layer   Laye [... truncated]
  80: stop
  79: execGRASS
  78: MarkTheEnds
  77: GetBaseNetworkNTransform

Thanks and Kind regards,

Mehrdad
