Problems starting grass7 from tcsh

Description

I am unable to start grass from tcsh. The following error occurs:

Traceback (most recent call last):
  File "../../dist.i686-pc-linux-gnu/grass70.tmp", line 941, in <module>
    csh_startup()
  File "../../dist.i686-pc-linux-gnu/grass70.tmp", line 670, in csh_startup
    mail_re = re.compile(r"^ *set  *mail *= *")
NameError: global name 're' is not defined

This may be related to a missing regular expression module import?

import re

will fix the bug on my system.

Getting grass7 started in a tcsh using the fix above and trying to start the gui result in an error:

> r.info
No protocol specified
Unable to access the X Display, is $DISPLAY set properly?


> echo $DISPLAY
:0

Yep. This should be fixed by r41652.

This is a separate issue. However, you might try:

export DISPLAY=unix:0

If that fixes it, it would appear to be an issue with your version of wxWidgets (possibly using xcb directly rather than Xlib?).

Setting the display variable unfortunately does not help:

grass_dev/grass_trunk> r.buffer
No protocol specified
Unable to access the X Display, is $DISPLAY set properly?
grass_dev/grass_trunk> echo $DISPLAY
:0
grass_dev/grass_trunk> setenv DISPLAY unix:0
grass_dev/grass_trunk> echo $DISPLAY
unix:0
grass_dev/grass_trunk> r.buffer
No protocol specified
Unable to access the X Display, is $DISPLAY set properly?
grass_dev/grass_trunk> setenv DISPLAY `hostname`:0
grass_dev/grass_trunk> r.buffer
Unable to access the X Display, is $DISPLAY set properly?
grass_dev/grass_trunk>
grass_dev/grass_trunk> wx-config --version-full
2.8.10.1
grass_dev/grass_trunk> cat /etc/SuSE-release
openSUSE 11.2 (i586)
VERSION = 11.2
grass_dev/grass_trunk>

As default the variable DISPLAY set to :0 in my shell, which works with any other programs outside of grass.

Is this still an issue?

X Display got removed from GRASS GIS 7 - this report is 5 years old. Closing.
