WinGRASS 6 Current Status
This page describes the current status of winGRASS development. Precompiled native winGRASS packages are available here.
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 (are these signals important?)
- wait() in:
- i.ortho.photo/photo.2image: wait()
- i.ortho.photo/photo.2target: wait()
- i.points: wait()
- i.vpoints: wait()
- Note: also in lib/gis/popen.c and lib/gis/system.c (use those implementations?)
- r.terraflow: getrusage()
- Vector-DB connection:
- M Lennert: I had hoped that Radim's patch for dbmi_client (http://grass.itc.it/pipermail/grass5/2006-December/028118.html) might solve the issue I've had with the db protocol errors, but apparently this is not the case. When I push the 'show the attribute columns' in a vector panel, I still get
******* Displaying column types/names for database connection of layer 1: dbmi: Protocol error Cannot open table <streams> ******** and a 'v.db.select' on the same map gives me: ******** 'vector/streams' was found in more mapsets (also found in user1). dbmi: Protocol error Cannot open select cursor *********
- P Kelly: I can confirm similar problems. I tried to import a Shapefile with v.in.ogr. I went quite deep into debugging it and got nowhere at all, although I should have taken better notes. I did confirm though that compiling the library with -mwindows as Radim suggested on the list made no difference either. I think trying with a different database, PostgreSQL perhaps is the next big step to debugging this. See if the behaviour is the same as with dbf and if not we can isolate it a bit more.
Known problems
- metacharacter escape in "sh -c '$cmd'"
- modules not working: r.proj (v.proj too?), r.surf.rst, v.neighbors, v.kernel, r.cost
- Cannot open Help pages.
- Have to add c:\mingw\bin to PATH on some systems.
- You should have typed c:/mingw instead of c:\mingw when asked by the MinGW installer.
- Have to type "exit" in the console to save ~/.grassrc file. Then, close gis.m to finish the session.
- A previous installation of grass under cygwin is likely to cause problems with WinGrass. Follow the directions to remove cygwin at http://cygwin.com/faq/faq-nochunks.html#faq.setup.uninstall-all
The following items cannot be fixed in the near future:
- Cannot display a thematic layer.
- d.vect.thematic requires PNG driver, which is not available in winGRASS.
- can't read "_data(.gronsole.gronsole,4,donecmd)": no such element in array error
- Aqua TclTk solution: http://intevation.de/rt/webrt?serial_num=5096&display=History
TclTk issues
- cannot run shell scripts: only .com, .exe, .bat
- sh -c '$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}
Other libraries
GDAL
- lib/gis/OBJ.*/fmode.o is needed for any GRASS related modules.
- modified ltmain.sh to install binary files from wrapper scripts.
