WinGRASS 6 Current Status

This page describes the current status of winGRASS development. Precompiled native winGRASS packages are available here.

Known problems

• Have to add c:\mingw\bin to PATH on some systems.
  • Shouldn't the MinGW installer add c:\mingw\bin to PATH?
• Cannot display a thematic layer.
  • d.vect.thematic requires PNG driver, which is not available in winGRASS.
  • can't read "_data(.gronsole.gronsole,4,donecmd)": no such element in array error
  • Aqua TclTk solution: http://intevation.de/rt/webrt?serial_num=5096&display=History

TclTk problems

• cannot run shell scripts: only .com, .exe, .bat
  • sh -c '$cmd'
• var=val style argument is not valid for batch files: equal sign is a separator like a space. http://support.microsoft.com/?kbid=71247 http://www.gatago.com/alt/msdos/batch/17358926.html
  • need .exe wrapper for shell scripts? grass-xterm-wrapper.exe
• file command returns bad code (catch is needed): http://sources.redhat.com/ml/insight/2003-q1/msg00079.html
  • catch {file copy}
  • catch {file delete}
  • catch {file rename -force} does not work. Delete old file first: catch {file delete}; catch {file rename}
• file redirection (>@stdout, 2>@stderr) does not work: http://wiki.tcl.tk/672
  • exec a batch file doing redirection (>&2, 2>&1)
• no -permissions file attributes
  • catch {file attributes -permissions}

What is missing?

• Display drivers: socket
  • Use gis.m instead of monitors.
  • Make gis.m Output window more like xterm. No need to hit Run.
  • Is there any way that the Map Display in gis.m can interact with console commands? IPC? File Alteration Monitor?
• i.class: SIGALRM, SIGTSTP
• i.ortho.photo/photo.2image: wait()
• i.ortho.photo/photo.2target: wait()
• i.points: wait()
• i.vpoints: wait()
• r.terraflow: getrusage()
