[gdal-dev] Python GDAL ImportError: ... undefined symbol: CPLGetErrorCounter

[Chiara Marmo]

Hello,

I'm on Fedora28
I'm working on a custom version of GDAL (only fitsdataset.cpp is modified), up to date with the last upstream version from github.

I need to test python bindings: so I've followed the instructions here[1] in order to have them linked with my gdal version.
The build process went fine.
But when I try to import gdal in my local jupyter notebook the following error is thrown

from osgeo import gdal

Am I doing something wrong?

BTW, I know it's a detail, but maybe in [1] it could worth to add that bindings for python3 are built with the command "python3 setup.py build" ... I always forget it... :(

Thanks for listening,
Best
