[mapserver-users] Fwd: Mapserver and Zope

[Jean-Francois.Doyon at ccrs.nrcan.gc.ca]

Hello,

I experienced the same problem a while ago (The draw() fucntion kept bombing
on me), but never found the solution :(

For now I have integrated mapserver into Zope using urllib, backend calls to
the mapserver cgi, and a structured template. Not as "integrated" as using
Python MapScript and far less flexible, but very fast, simple, and stable.

I however never had success even building mapscript for mapserver 3.6.1 ...
How did you guys do it? I get a bunch of errors about "ms_error" being
undeclared. even Frank had mentionned this would not be fixed until 3.7 ...
And right now for me 3.7 isn't compiling ...

I would *REALLY* like to get this working!

J.F.

Sven, 

I've seen and overcome each of these issues.

Any Zope method that uses mapscript should be an
external method because you'll need to access a 
map file on the filesystem.  As well, if you want
to use the module 'sys', you'll need to make 
drawmap() into an external method.  

Next, you need to build mapscript using the same
python version as comes with Zope.  If you're using
Zope 2.5, you'll need to build python mapscript
with python 2.1, and then install mapscript inside
Zope's own python.  You can do this manually or by
using a --prefix option with the setup.py script.
Once you get a mapscript installed among your other
Zope python modules, you should be ready to go.

Now, the drawing errors: I experienced some problems
like this with the 3.5 version of mapserver, and the
problems went away when I moved up to mapserver 3.6 
and 3.7.  So, honestly, I didn't overcome this
problem, but jumped over it.

Hope this helps.  cheers,
Sean
