[gdal-dev] Test problem After Merge

[Even Rouault]

Andrew,

first, check that you can use the command line utilities like gdalinfo, 
so you may need to adjust your PATH, DYLD_LIBRARY_PATH and GDAL_DATA. 
The Bash script scripts/setdevenv.sh might help setting up stuff (not 
totally sure if it works on Mac though).

Also try in a Python interpreter "from osgeo import gdal" to see if the 
exception is more verbose. If your GDAL lib links against libraries that 
are not in the default library search path, GDAL command line utilities 
might still be able to find them, but loading libgdal through the Python 
bindings might fail (at least that happens to me on Linux, cf 
https://github.com/OSGeo/gdal/pull/9783)

Also try otool -L on libgdal.dylib and on _gdal.cpython-312-darwin.so

Actually your issue looks superficially like the one we have in our CI 
since a few days : https://github.com/OSGeo/gdal/issues/9723 / 
https://github.com/actions/setup-python/issues/849 . Python bindings on 
macos-14 arm64 github were working fine, and suddenly broke at runtime 
with an exception similar to you whereas nobody significant changed 
between working and non-working builds. It looked correlated to some 
update on the github action components, but perhaps that's something 
else. Do you know if there was an operating system update on your system 
recently?
