<p>Hi Vaclav,</p>
<p><br>
</p>
<p>Thanks for your suggestions</p>
<p><br>
</p>
<p>I already tried obtaining the gisbase from the binary but got the same error, so i then switch to the shorthand way (besides, instaling grass through the Osgeo4w doesn't create a grass70.bat in the </p>
<div>C:\OSGeo4W\apps\grass\grass-<wbr>7.0.4 folder, the bat seems to be only created using the standalone grass installers).<br>
<br>
Using this way I'm getting the same stacktrace.<br>
<span>script.run_command('g.list', flags='m', type='raster')</span><br>
<br>
Running the os.environ shows me several variables, the more relevants I suppose are<br>
<span>'PYTHONPATH': 'C:\\OSGeo4W\\apps\\grass\\grass-7.0.4\\etc\\python'</span><br>
<span>'GISBASE': 'C:\\OSGeo4W\\apps\\grass\\grass-7.0.4'</span><br>
<div><span></span>'GISRC': 'c:\\users\\Carl\\appdata\\local\\temp\\tmprv4iwf'<br>

'GDAL_HOME': 'C:\\Program Files (x86)\\GDAL'<br>
'PYTHON_HOME': 'C:\\Python27'<br>
'SAGA_HOME': 'C:\\Saga'<br>
</div>
<br>
I forgot to mention in the first mail that before getting the stack trace a popup appear saying this<br>
<br>
===<br>
Microsoft Visual C++ Runtime Library<br>
<br>
Program<br>
C:\OSGeo4W\apps\grass\grass-7.0.4\bin\g.gisenv.EXE<br>
<br>
R6034<br>
An application has made an attempt to load the C runtime library incorrectly.<br>
Please contact the application's support team for more information.<br>
===<br>
<br>
And then another popup with a g.gisenv.exe application error printing the error 0x0000142.</div>
</div>
<br>
<br>
<div>What i discover is that if I remove gdal from PATH environment, the error change to "iconv.dll missing" but with a similar stacktrace<br>
<div><br>
===<br>
grass.exceptions.CalledModuleError: Module run None ['g.gisenv', '-n'] ended with error<br>
Process ended with non-zero return code -1073741515. See errors in the (error) output.</div>
===<br>
<br>
<br>
</div>
<br>
Maybe has something to do that my OS is Win 7 x64 ? I choose the x32 as my system wide python is x32.<br>
</div>
<p></p>
<br>
Thanks!<br>

<div>Unrelated, but this is not guaranteed to work. Use the syntax:<br>

gscript.run_command('g.list', flags='m', type='raster')<br>

<div><br>
<p>According to my Internet search, -1073741502 means STATUS_DLL_INIT_FAILED - DLL Initialization Failed. So perhaps the installation is somehow broken or the paths are not set right. You can try</p>
<p>print os.environ</p>
<p>after init() call to see how the paths are set.</p>
