[mapserver-users] Building Mapscript/Python

[Thorsten Fischer]

Jean-Francois,

This posting is about a week old, I apologise if it was answered before but I
do not follow the list very closely at the moment.

I have not built python/mapscript yet, but I know a bit of python. In Python,
to create an instance of an object you do something like:

map = mapObj ("/home/mapdata/legalsurveys/test.map")

The method __init__ is the constructor of a class, which is always defined as
something like 

def __init__ (self, ...)

So if you do the call described above, it passes its own instance and then the
arguments to the constructor. You do not call any new() function or the
__init__ thing directly.

No. Never. This is python =)

For the compiling process maybe, the above is general python knowledge.


hope that helps,
