Description (last modified by hamish)

I'm running GRASS 6.4-svn in a Linux Machine (CENT OS) and I needed to run i.ortho.photo but I got this error:

Try turning off debug messages;

but that fails from the wx command console because it tries to parse the second "=" in g.gisenv set="DEBUG=0"

By doing: g.gisenv set="DEBUG=0" If if insert i.ortho.photo in command line, it opens the i.ortho.photo menu But If I choose in GUI menu it gives the following error: Exception in thread Thread-9: Traceback (most recent call last):

And opens a blank xmonitor

AFAICT in gui/wxpython/gui_modules/gcmd.py the "wait" variable should be True/False, but that should print out ok as a %s string.

I've got no idea how that could be turning itself into a list.

  • note at this point in the code it has already failed, this is in the error handling logic)
  • see also ticket #693; the XTerm stuff has not all been backported from 6.5. I'm not able to test 6.4 right now, but in the very latest 6.5svn it works for me.

workaround: from the command prompt do:

d.mon x0
i.ortho.photo

Hamish

ps- put { { { ... } } } (with no spaces in between) around formatted text to show it verbatim.

With d.mon x0 command I got a windows saying "Command 'd.mon' not yet implemented so there is no way I can test that. If I insert i.ortho.photo in command windows it works (I as far as I can see). How can I change menudata.xml in order to avoid this error?

Hamish:

Nikos:

Sorry to be confusing, I meant the terminal command prompt, not the GUI one. (the xterm, gnome-terminal, etc. at the GRASS> prompt)

If I insert i.ortho.photo in command windows it works

(the xterm, gnome-terminal, etc. GRASS> prompt, right?)

somehow in the wxPython code the "wait" variable is becoming a list on your system. That doesn't happen for me and I don't see any obvious reason for it in the code. A more expert wxPy'er than myself would need to tell you why and how to fix it.
