[GRASS-dev] g.extension not working on debian - grass 6.4.3svn

[Paulo van Breugel]

Just recompiled grass 6.4 (completely clean):

* The earlier mentioned problem with g.html2man not being in the right 
folder was solved, it appears in the tools folder now

* It did not solve the problem of omitting the parameter part in the 
manual page. When installing addons (tried script and py addons) using 
the g.extension gui interface (only showing the error messages):

...
ERROR: G_getenv(): Variable LOCATION_NAME not set
....
ERROR: G_getenv(): Variable LOCATION_NAME not set
...
WARNING: Unable to parse 
'http://grass.osgeo.org/addons/grass6/modules.xml'. Metadata file not 
updated.
Installation of <r.csr> successfully finished

* The addon does not appear in the list when using the 'remove 
extension' gui interface

All is run from within GRASS (using the menu 'settings-addon 
extensions'). Just to be complete, running e.g, r.mess 
--html-description from the command line does give the expected html 
file with the NAME, KEYWORDS and SYNOPSIS sections (i.e., the ones left 
out in the manual tab).

Cheers,

Paulo
