#1776 closed defect (fixed)

Python error by startup

Reported by: pvanbosgeo Owned by: martinl
Priority: normal Milestone: 7.0.0
Component: Startup Version: svn-trunk
Keywords: language settings, locales, i18n Cc: grass-dev@…
CPU: x86-64 Platform: Linux


Hi, I just compiled / build GRASS 7.0 from source and got the following error message when starting up GRASS:

Popup 'Python error':

Cannot set locale to ".

Messages on command line:

Failed to set LC_ALL to None.UTF-8

(process:14771): Gdk-WARNING : locale not supported by C library

(process:14771): Gtk-WARNING : Locale not supported by C library.

Using the fallback 'C' locale.

These messages appear twice; directly at start up and then again when the Layer manager and Display open.

My system information:

GRASS version: 7.0.svn GRASS SVN Revision: 53615 GIS Library Revision: 52468 (2012-07-27) GDAL/OGR: 1.9.2 PROJ4: Rel. 4.7.1, 23 September 2009 Python: 2.7.3 wxPython: Platform: Linux-3.5.0-17-generic-x86_64-with-Ubuntu-12.10-quantal

This problem started with the latest revision. However, I installed this latest revision after upgrading to Ubuntu 12.10, so perhaps that has broken something concerning the locale?

I see the Milestone is set to 6.4.3. Just to make sure, these problems are with GRASS 7.0, not with GRASS 6.4

When starting R from within GRASS, I am getting the following lines, which do not show when started R normally (not from within GRASS) from the command line:

During startup - Warning messages: 1: Setting LC_CTYPE failed, using "C" 2: Setting LC_COLLATE failed, using "C" 3: Setting LC_TIME failed, using "C" 4: Setting LC_MESSAGES failed, using "C" 5: Setting LC_PAPER failed, using "C" 6: Setting LC_PAPER failed, using "C" 7: Setting LC_MEASUREMENT failed, using "C"

I am guessing this has the same underlying problem?

this error should be avoided in r53620. Can you try it out, please?

Messages on command line:

Failed to set LC_ALL to None.UTF-8

Strange, what says

 env | grep LANG


locale -a

> LANG=en_US.UTF-8

do you have this locale installed? Check locale -a...

your currently used locale seems to be available. Hm, strange.

comment:11 by pvanbosgeo, 12 years ago

just tried r53623 and only one error message on the command line (Failed to set LC_ALL to None.UTF-8 (unsupported locale setting)). No pop-up window with error message anymore and no error messages when starting R from within GRASS.

Paulo, could you, please, try GRASS 7 after r59176 ? I changed a bit language overriding code in startup script to avoid problems like you had and still be able to keep language override.

Hi Marisn,

Yes, there is no error message anymore.. thanks!

Should I mark this ticket as fixed, or will you do that?
