Hi,
I think I am banging my head on this error #3981
I posted my problem to grass-user, but no response.
Is there a possible workaround for me?

Thanks,
Zoltan.

Hi,
I’m using EPSG 2932 and QGIS etc all are OK with it.

I have installed everything using OSGeo4W64, so how come Grass does not use the same projections database (as QGis etc)?
(and please can I have a pointer as to how to introduce EPSG 2932 to Grass 7.8.1)

Thanks and regards,
Zoltan
