[GRASS-user] Error 126 with Windows 10

John_Wall · July 12, 2017, 6:09pm

Hello,
I am attempting to get GRASS 7.2.1-1 installed on my Windows 10 machine using the Osgeo4w Set-up x86 utility. I chose Advanced Install and then Install from Internet. After installing and restarting my machine, I tried to start GRASS, but got the following error:

Hello all,
I talked with Vashek offline and he metnioned I should try to uninstall and reinstall. I did that. We then tried d.rast which threw this error:

he then recommended g.region -p which told me “gdal201.dll”. He then recommended I post this to the mailing list. Any one have any ideas?

Do you other python installations on your system (and in path)?

GDAL in OSGeo4W was updated to 2.2. Apparently GRASS is still linked to GDAL
2.1 and the package does have a dependency to gdal201dll, which would install
gdal201.dll. Installing gdal201dll should help.

Hello Helmut and Juergen,
I talked with Vashek some more offline and it seems that the issue has something to do with Windows. Since I can get GRASS 7.0 to work on my Ubuntu machine, I’ll just use it on there.
Best,
John

Hi John,

Of course. I now added a dependency to the osgeo4w package. gdal201dll should
now be installed automatically.
