[GRASS-dev] libgrass_gis.7.8 not found issue

[Pedro Venâncio]

Hi all,

I've installed GRASS 7.8.5 from new OSGeo4W installer [0], but when I run
GRASS and try to start a new session I get:

Cleaning up temporary files...
D1/1: G_set_program_name(): clean_temp
D1/1: G_set_program_name(): db.connect
D1/1: Creating new default DB params with db_set_default_connection()

This seems to affect Windows 10 operating systems in locale languages,
in this case, portuguese, where the issue is confirmed on 3 different
machines.

I've reported it in OSGeo4W tracker [1], because I thought it was
related to some kind of packaging issue, but I decided to post it here
to get your opinions.

Thank you very much.

Best regards,

Pedro Venâncio
