[GRASS-dev] check on GRASS revision number

[Markus Neteler]

Hi,

just for the record, by chance it happened to me today and how I
solved it easily:

GRASS 7.0.0svn (nc_spm_08_grass7):~ > r.stream.order
stream_rast=streams at user1 direction=direction at user1
elevation=elevation at PERMANENT accumulation=accum at user1
stream_vect=streams horton=horton
ERROR: Module built against version $Revision: 62395 $ but trying to use
       version $Revision: 63222 $. You need to rebuild GRASS GIS or
       untangle multiple installations.


# Now simply re-run g.extension:
GRASS 7.0.0svn (nc_spm_08_grass7):~ > g.extension r.stream.order
