I have a piece of software that embeds python using libboost-python. It
creates a python module in C++ runtime, and then imports it from python code.
For python2.7 this works well.
See test_module.py and test27.cpp attached.
On Debian Stretch it can be build using command
g++ test27.cpp -I /usr/include/x86_64-linux-gnu/python2.7 -I /usr/include/
python2.7 -lboost_python -lboost_system -lpython2.7
As I've said It works as expected. Python code imports _hello_provider module
that have been created in C++ code, and uses provide_hello() for printing.
I've tried to port it to python 3.x, and did not succeed.
I managed to write test3x.cpp, it build well on Debian Buster using command
g++ test3x.cpp -I /usr/include/x86_64-linux-gnu/python3.9 -I /usr/include/
python3.9 -lpython3.9 -lboost_python39 -lboost_system
but it fails when I try to run it.
Traceback (most recent call last):
File "/usr/lib/python3.9/imp.py", line 169, in load_source
module = _exec(spec, sys.modules[name])
File "<frozen importlib._bootstrap>", line 613, in _exec
File "<frozen importlib._bootstrap_external>", line 790, in exec_module
File "<frozen importlib._bootstrap>", line 228, in _call_with_frames_removed
File "test_module.py", line 1, in <module>
import _hello_provider
ModuleNotFoundError: No module named '_hello_provider'
for some reason "native" python module does not see _hello_provider that have
been created in runtime.
I guess I am doing something wrong, but I am no expert in python and python
embedding, and I did not managed to find any good example in the internet.
So I guess I need some help here.
P.S. If remove "import" related part from examples, it also works well, so the
only task here is to make in properly visible...
