Thought I had finally got Python, GDAL and QGIS to play nicely together but just tried to do a batch transform using a bash script to call gdalwarp and it claimed it couldn't read the libproj.dlib file. Tried the exact same transformation in QGIS and it worked. Copied the code from QGIS into bash shell and it failed. QGIS is calling the same GDAL library so I don't get this at all. Anyone got any ideas? This seems to be connected somehow, not sure how, to the EPSG codes for Swedish grids being changed every five minutes and the libraries not being up to date. That said why does QGIS manage the job when bash doesn't?
and so added
to my .bash_profile
it works! I'm still running OSX 10.7 and I haven't needed this in my profile before so why I should need it now I can't say by the whole issue with paths is beginning to get a bit tiresome.
