Bug 106877 – grass-6.0.1 should require tcltk, because it uses the wish command

• Product: Gentoo Linux
• Status: RESOLVED FIXED

grass-6.0.1 has tcltk as a use flag, but it always uses the wish command, which
is missing if you don't have tcltk

Reproducible: Always
Steps to Reproduce:

I'm not sure I understand this; yes Grass has USE flag for tcltk, which installs 
both the tcl and tk packages.  This is required for some of the Grass GUI 
features, however, I believe X is the only hard requirement.  There are reasons 
to build without tcltk support (eg, libgrass support for gdal), so what exactly 
is the problem?

I emerged grass-6.0.1 without the USE flag for tcltk set and the grass startup
script (grass60) complained about the missing "wish" command, which seems to be
part of tcltk, so it think this should be hard requirement.

By "complaining", do you mean that installation failed, or was it just a 
warning? If installation failed, please post the resulting error message.

it installs fine, but if you try to run the grass60 start-script at some point
it fails and tells you that the wish command is missing. so grass60 is unusable
without tcl/tk enabled.
to reproduce rename the wish command to some other name and try running grass60.

It looks like Grass 6.x now indeed requires the wish tcl shell; it's no longer a 
USE flag in newer Grass (6.0.1 to be precise).
