Thanks Martin, In mean time I switched to python 2.5 and I succeed to include qgis libraries.
I wanted to be independent from OSGeo4 because when I wanted to use pyDev for debugging code, I couldnt use python.exe interpreter from OSGeo4 installation folder. I got some strange errors when I wante to reference to python.exe. Also another problem was that I used unstable version of OSGeo4, so maybe that caused also problems. Just thinking... Anyway, thx a lot for answer Cheers Minja On Fri, Jul 16, 2010 at 1:03 PM, Martin Dobias <[email protected]> wrote: > Hi Minja > > On Fri, Jul 9, 2010 at 10:19 AM, Minja <[email protected]> wrote: > > Im trying to create standalone python application that will use PyQT4 > > libraries and QGIS libriaries.
