PYTHONPATH and PATH system variables

Question

I am working with quantum gis 1.7.2.During installation it creates python25 folder. I am working with python2.6 for python plugins for QGIS. i set system variable as:

PATH :=C:\Program Files\Quantum GIS Wroclaw\apps\qgis
     C:\Python26\Lib\site-packages\PyQt4\bin 
PYTHONPATH:=C:\Program Files\Quantum GIS Wroclaw\apps\qgis\python;

ErrorMessage

Traceback (most recent call last):
File "C:\rt_sql_layer_working\DlgQueryBuilder.py", line 30, in <module>
from qgis.core import *

ImportError: DLL load failed: The specified module could not be found.

is this because of version mismatch or paths are wrong??

Answer 1

Start the python in python25 folder and at the prompt do

   from qgis.core import *

If this is working fine, perhaps there are additional libraries provided with this python25 which are not present in 2.6.

You might need to copy these dll's to your python2.6 installation

Answer 2

Normally you'd just want your PATH to be something like c:\PYTHON26 or c:\PYTHON25 not the one you've specified:

C:\Python26\Lib\site-packages\PyQt4\bin
