[FreeNX-kNX] Tk problem

[Markus Neteler]

Hi,

(I got the recommendation to ask on this list, hope that's right)

We try to run GRASS GIS (http://grass.itc.it/) over FreeNX but
have following problem:

Starting GRASS ...
Application initialization failed: this isn't a Tk applicationunknown
color name  "Black"
Error in startup script: can't invoke "image" command:  application

   while executing

   (in namespace eval "::help" script line 27)

   (file "/usr/local/grass-6.1.0/etc/help.tcl" line 61)
   invoked from within
"source $env(GISBASE)/etc/help.tcl"
   (file "/usr/local/grass-6.1.0/etc/gis_set.tcl" line 38)
/home/manganelll/<UNKNOWN>/<UNKNOWN>/.gislock: No such file or directory
ERROR: /usr/local/grass-6.1.0/etc/lock:

A colleage told me that the problem is actually with wish:

$ wish
Application initialization failed: this isn't a Tk application unknown 
color name "Black"

So any tk application seems to fail with freenx. 

Any hint would be welcome. In general, the Tcl/Tk part of GRASS works fine on
numerous platforms.

thanks

Markus
