r.le.setup fails on WinGRASS due to missing xterm

[msieczka]

In the most recent 6.4 nightly build ​http://josef.fsv.cvut.cz/wingrass/grass64/WinGRASS-6.4.SVN-r43715-1-Setup.exe r.le.setup called from wxGUI fails in following way:

Traceback (most recent call last):
  File "c:/Program
Files/GRASS-64-SVN/etc/wxpython/wxgui.py", line 1011, in
OnXTerm

del os.environ['GRASS_RENDER_IMMEDIATE']
  File "C:\Program Files\GRASS-64-SVN\Python25\lib\os.py",
line 441, in __delitem__

del self.data[key.upper()]
KeyError
:
'GRASS_RENDER_IMMEDIATE'

On Debian Squeeze, built from r43697 of releasebranch_6_4, it starts, but some error crops out too:

Traceback (most recent call last):
  File "/usr/lib64/python2.6/dist-
packages/wx-2.8-gtk2-unicode/wx/lib/agw/flatnotebook.py",
line 3989, in OnLeftDown

afaik r.le.* on wingrass should have been greyed out and unavailable.

WinGrass6.4.svn: all r.li-stuff is greyed out, but not the r.le-stuff.

r.le.setup requires xterm (indicated in the menue). is this available on windows?

but very interesting, if you type r.le.setup in the wx-gui-command-line or in the msys-command-line, the r.le.setup-wx-gui pops up.

r.le.setup and r.le.trace require an Xmon to function, and will not work in native WinGrass. Suggest that it be grey'd out.

AFAIK both r.le.* (requires xmons) and r.li.* (requires unix sockets) will work in the cygwin build.

ghelp.py pops up a message explaining that you have to run the command from the terminal for OnXTerm.

how to detect if we're on win32 but running cygwin?

currently the native wingrass error for r.le.setup is:

Traceback...
   File "c:\program files\grass ...\wxpython\lmgr\frame.py" line 1148, in OnXTerm

xmon = xmonlist[0]
IndexError
:
list index out of range

seems like that would be reasonably easy to catch, and it should do, but it's pretty easy to just not build the two problematic programs if X11 is not present. (done in devbr6 in r50699, please test)

technically r.le.setup is interactive on the Xmon and interactive in the terminal; and r.le.trace draws to the graphics driver but is not interactive with it, but does use G_yes() so needs to run from an interactive terminal.

the r.li ones are all successfully greyed out as they were never built.

r.digit and i.class are not built, so greyed out successfully.

g.setproj on native WinGrass fails with a Traceback error (KerError in OnXTerm: del self.data[key.upper()] Global name 'Command' is not defined); but should be present and should work from the command prompt.

r.le vs. wingrass patches backported to relbr64 in r50703.

all OnXTerm menu items seem broken currently in 6.5svn wxgui (linux too) but seem to work in 6.4svn.

closing bug as fixed. OnXTerm breakage in 6.5svn continued in #945.
