[Qgis-user] qgis 1.7.4 and libgdal

[Agustin Lobo]

Does qgis 1.7.4 (from binaries in ubuntugis-unstable for 10.04)
require libgdal1-1.8.0 and python-gdal 1.8.0 or can it work with
libgdal1 1.9 and python-gdal 1.9?

I keep on with the following dilemma:

1. If I install python-gdal 1.9 I get startup errors such as:
Couldn't load plugin openlayers due an error when calling its
classFactory() method

Traceback (most recent call last):

ImportError: /usr/lib/python2.6/dist-packages/osgeo/_gdal.so: symbol
VSIFTruncateL, version GDAL_1.9 not defined in file libgdal.so.1 with
link time reference

2. If I use python-gdal 1.8.02, no startup problems but cannot use
gdal tools (within or outside qgis).
