Hello,
we have a problem with g.extension, that seems to be the same that was discussed here a few days ago in the "r.stream.order export to shapefile" thread. There is also a ticket at http://trac.osgeo.org/grass/ticket/1721 but I do not fully understand the reason why the bug is invalid.
I have a grass version 6.4 downloaded, built and installed from source. When I now try to install an addon with
g.extension extension=v.in.gshhs operation=add prefix=~/grass_addons/vector/
I get the error stating that [...]/grass-6.4.3svn/tools/g.html2man: is a directory
I can follow the discussion so far, that in the source tree "include/Make/Man.make" points to "tools/g.html2man/g.html2man", while in the installed tree it is changed and points to "tools/g.html2man". But the first comment says "the script used to be installed into tools/g.html2man/g.html2man, but is now just installed as tools/g.html2man." and this seems to be wrong. I have a clean installation, and in the install tree the file "g.html2man" is located in the directory "tools/g.html2man" and not directly under "tools".
The ticket refers to http://grass.osgeo.org/wiki/Compile_and_Install#Addons and there the addons are compiled and installed from source. Is that an alternative way to g.extension and should both work?
