Pybind11 build with poetry - static-libraries

Question

I am currently trying to build a small pybind11 extension and to integrate smoothly with our current setup, it would be neat if that would work with poetry build && poetry install
from pybind11.setup_helpers import Pybind11Extension, build_ext
def build(setup_kwargs):
ext_modules = [
Pybind11Extension(
"my_module",
["folder/one.cpp", "folder/another.cpp"],
include_dirs=[".", "my_static_lib/include/"],
extra_compile_args=['-O3', '-pthread'],
language='c++',
cxx_std=11
),
]
setup_kwargs.update({
"ext_modules": ext_modules,
"cmd_class": {"build_ext": build_ext},
"zip_safe": False,
})
That compiles all fine, but since I don't know how to inform the linker about the static library that I depend on, I have undefined symbols when I load the package.
Any idea how that works?
Is this an odd thing to try?
Thanks for your help or comments!

Answer 1

It was actually quite simple, I just did not find the documentation anywhere. There is an argument called "extra_link_args", where I can specify all these things:
def build(setup_kwargs):
ext_modules = [
Pybind11Extension(
"my_module",
["folder/one.cpp", "folder/another.cpp"],
include_dirs=[".", "my_static_lib/include/"],
extra_compile_args=['-O3'],
extra_link_args=['my_static_lib/libmystatic.a', '-lbz2', '-pthread'],
language='c++',
cxx_std=11
),
]
setup_kwargs.update({
"ext_modules": ext_modules,
"cmd_class": {"build_ext": build_ext},
"zip_safe": False,
})
I still haven't figured out how do specify the compiler, but fortunately, it works for now with the default compiler on my mac.
