Re: Debugging Gandiva failures in python CI tests
Thanks Wes, that worked.
When I run the gandiva tests (I did a step-through with pdb), I get this error :
-> schema, [expr], pa.default_memory_pool())
LLVM ERROR: Program used external function '_ZNSt8ios_base4InitC1Ev' which could not be resolved!
I had hit the same issue with java/jni, and resolved it by doing a NativeLibrary.getInstance() (thanks to @pitrou). My knowledge of python is limited - can someone please help with the same for python ?
Thanks & regards,
