[postgis-users] Re:mezoGIS problem

[Stephen Davies]

I have fixed the glib error and added the .mezogis directories/files.
This removes the startup messages but leaves:

bash-3.1$ mezogis.py
Another module named "tesselate" is already in use.
load "/usr/local/share/mezogis/plugins/tesselate.py"
Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/local/lib/python2.4/threading.py", line 442, in __bootstrap
    self.run()
  File "/usr/local/lib/python2.4/site-packages/mezoGISlib/_dbtools.py", 
line 86, in run
    row = c.fetchone()
  File 
"/usr/local/lib/python2.4/site-packages/GeoTypes/_PsycopgInit.py", line 
92, in __call__
    if ord(s[0]) < 32:

Python 2.4 Psycopg 1.1.21.

Cheers,

Hi,

I agree with you. First error seems permissions related.

The second error is a complain about the database. mezoGIS needs a
directory $HOME/.mezogis with some data or it'll try default values,
and the default values includes a conection to localhost.

Try this (with the user you launch mezoGIS):

$ mkdir ~/.mezogis
$ mkdir ~/.mezogis/plugins
$ touch ~/.mezogis/history

Now you start mezoGIS and change the database connection parameters;
if still fails, try also the following with your parameters.

$ cat > ~/.mezogis/mezogisrc
[connection]
port = 5432
host = your_postgresql_server
user = postgres
dbname = your_geodatabase_name
pw =
^D

Good luck,
M.
