Re: [GRASS-user] Compiling GRASS 7.9 using zstandard source
Hi, perhaps you don't have to use zstd, just configure grass with --without-zstd, GRASS will then use different compression. Alternatively you would have to build it locally, not sure how difficult that is.

[GRASS-user] Can someone help me troubleshoot GRASS on Windows 10
Hi GRASS users, Longtime GIS'er but newbie to GRASS. I've never been able to get it to work properly on my workstation and have always fallen back on Esri or, QGIS built-in functions. Now I am in a situation where I have to get GRASS to work because it seems like the fastest way to do some hydro things. I am trying to use it inside of QGIS 3.12. Here is my problem. I have a UTM-projected DEM as input, I just want to run r.flow and it fails, reporting: "The following layers were not correctly generated. C:/Users/username/AppData/Local/Temp/1/processing_ipancU/89aab5fc64c6999046d99c2e0028b/flowaccumulation.tif C:/Users/username/AppData/Local/Temp/1/processing_ipancU/bded4092193446b883446b88344c55272310fa8/flowlength.tif C:/Users/username/AppData/Local/Temp/1/processing_ipancU/f4a65331b4ef4fa5a6b2ba826efdd9b4/flowline.gpkg You can check the 'Log Messages Panel' in QGIS main window to find more information about the execution of the algorithm." However, when I check the log messages panel, here is what I see: Grass7 tab: only INFO level messages showing the original command payload all the other tabs: nothing So, not much given to troubleshoot. This behavior happens with *every* GRASS tool I try to run, including even v.buffer. So something is definitely not right. *About my setup* I do not have admin access rights to my workstation as this is a production box in a big enterprise. However I do have access to write to C:/ directories outside of the typical locked down stuff (Program Files, Program Files (x86), etc). I have QGIS currently installed to C:\QGIS_3 and GRASS sits under that. The workstation is not connected to the internet in case that matters.

Re: [GRASS-user] R: exwcuting grass python script from php web page
Hi Roberta,
I'm really no expert in this domain, so just doing some educated guessing.

Sorry, maybe I didn't explain myself well because actually, I don't get

I checked the import of the grass libraries (print(sys.modules)) and
they seem to be correctly imported.
Have you checked your webservers error logs ?
I have already checked and this is the error in the webserver log file
File "importgrass.py", line 82, in
main()
File "importgrass.py", line 71, in main
rcfile = gsetup.init(gisbase, gisdb, location, mapset)
File "/usr/lib/grass74/etc/python/grass/script/setup.py", line 170,
in init
config_dir = os.path.join(os.getenv('HOME'), config_dirname)
File "/usr/lib/python3.6/posixpath.py", line 80, in join
a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not NoneType
First of all, the importgrass.py you sent only has 72 lines, so I don't
know what the line 82 reference in your above error points to.
But most importantly, I would really recommend that you upgrade to a
newer version of GRASS GIS. Current stable is 7.8. There's been a lot of
improvement in terms of python3 compatibility and maybe this is an issue
that has already been resolved.
It sounds like an issue with a variable containing a path. Apparently it
is of type NoneType...
How do you call the python script from PhP?
I tried both with:
and
and
$myfile = fopen("./tmp/script.sh", "w") or die("Unable to open
file!");
fwrite($myfile, $intestazione);
fwrite($myfile, $command);
fclose($myfile);
echo exec("/bin/sh ./tmp/script.sh", $output, $return);
print_r($output);
?>
What happens when you replace '/usr/bin/python3 importgrass.py ' by, for
example '/usr/bin/grass --version', just to check if other executables
work ?
