[GRASS-user] error instaling addons in Grass 7

[Luís Mário Ribeiro]

Hello all,

Reply to myself: downloaded i.histo.match.zip from http://wingrass.fsv.cvut.cz/grass70/addons/ and unziped i.histo.match.py to C:\GRASSGIS70svn\scripts.

Working properly now so I guess something is wrong in the grass instalation procedure.

Best regards
luis

Good morning list,

I installed Grass7 (WinGRASS-7.0.svn-r55270-516-Setup.exe ) on a winxp as i need to use i.histo.match (not present in 6). Installing from menu (gui) doesn't work (see att).

Tried manually and although it installs correctly this error message shows when executing it:

g.extension ext=i.histo.match

Unable to fetch interface description for command 'i.histo.match.py'.
Details: C:\GRASSGIS70svn\extrabin\python.exe: can't open file 'i.histo.match.py': [Errno 2] No such file or directory



Any thoughts?
Thanks in advance

my poor knowledge of C dissuaded me to investigate in this way...

in a way (except recourse to v.generalize), this is what is performed in my stack of commands.

Here again it points to the power of ps.map. With a couple of postscript lines you can do nearly whatever you want.

Yours,
