Description

Hi,

since r59163 I am getting following error when GRASS 7 is started. I am getting same error also in recent revisions (r59205):

Please, provide output of following commands:

locale (outside of GRASS and inside GRASS session)
locale -a
grep language ~/.grass7/wx

Ahh. I see. The new language override code is too tolerant - if no override is specified, it doesn't call setlocale() at all and thus process ends running with C locale.

Should be fixed in r59211. Reopen this bug if needed.

Hi,

Replying to turek:

Hi,

Try r59215. I changed a bit enforcing of locale on GRASS process and also worked-around gettext on Windows issue (it fails to load default locale translations as Windows doesn't set LANG by default).

comment:6 by turek, 10 years ago

Hi, I still get the same error. Maybe I am doing something wrong however r59162 works for me:

comment:7 by marisn, 10 years ago

I'm not able to reproduce the issue on my system no matter how hard I try.

Still the issue seems to be twofold - there was not robust enough code to set language/locale in startup script. It is fixed and from r59215 it should work just fine* The second problem is that now some problems with other wxgui code have popped-up. I.e. getdefaultlocale shouldn't be used to get encoding.

Can you, please, apply this patch and give me back output?

Can you, please, test after r59652? I added some extra care to the cases when Python fails to detect default locale. Generally it indicates on some kind of problem with system's locale.
