Self built python extension failure to link library
0%
Description
Reported by userL https://saxonica.plan.io/boards/4/topics/9261
There is a problem to self build the python library from the pypi directory.
Currently if we build the wheel with the command:
python3 setup.py bdist_wheel
or building the extension locallly:
python3 setup.py build_ext -if
It builds successfully (although user reported that they had to make changes in the setup file to locate the library). When we run a sample python script we get the following error:
Traceback (most recent call last):
File "/Users/ond1/work/saxondev/build/temp/libsaxon-EEC-mac-x86_64-v12.0/pypi/samples/saxon_example.py", line 1, in <module>
import saxoncee
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/saxoncee.cpython-39-darwin.so, 0x0002): symbol not found in flat namespace (_addProcessorDataPair)

This has been addressed with improved build scripts in the saxon12 branch.
The hec_python_build_wheel task (or pec_... or eec_...) builds a wheel that does not have libsaxon bundled.
The hec_python_repair_wheel task takes the wheel from the previous task and runs the platform-appropriate utility on it to bundle libsaxon correctly.
(There's also an hec_python_install_wheel which takes the repaired wheel and installs it into the Venv for the current branch, but that seems less relevant here.)
