Simple example of using pybind11 via Bazel.

bazel_pybind_sample's Issues

symbol not found in flat namespace errors on Mac OSX

I have not been able to get this example to work on my computer. I am using an Apple M1 computer, and consistently get

Traceback (most recent call last): File "/private/var/tmp/_bazel_connie/f24ab60b302356e3037695b783d4e5e0/sandbox/darwin-sandbox/74/execroot/__main__/bazel-out/darwin_arm64-dbg/bin/example_test.runfiles/__main__/example_test.py", line 9, in <module> import my_pb_mod ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/my_pb_mod-1.0.1-py3.10-macosx-10.9-universal2.egg/my_pb_mod.cpython-310-darwin.so, 0x0002): symbol not found in flat namespace '_PyInt_FromSsize_t'

I have been able to install it through g++ with the following command:
g++ -O3 -Wall -shared -std=c++17 -undefined dynamic_lookup $(python3 -m pybind11 --includes) my_pb_mod.cc -o example $(python3-config --extension-suffix), but I have not been able to install it through Bazel.

I thought it might be a seg fault issue with the dynamic library, but I ran the troubleshooting environmental variable PYTHON_BIN_PATH with Python 2.7 and 3.8, both result in the same error.

Has anyone fixed the issue with the symbol not found in flat namespace?
