This leads to an ambiguous overall configuration. If you want to distribute this package, please make sure that 'pyLandau.cpp' is explicitly added to the `packages` configuration field. Alternatively, you can also rely on setuptools' discovery methods (for example by using `find_namespace_packages(...)`/`find_namespace:` instead of `find_packages(...)`/`find:`). You can read more about "package discovery" on setuptools documentation page: - https://setuptools.pypa.io/en/latest/userguide/package_discovery.html If you don't want 'pyLandau.cpp' to be distributed and are already explicitly excluding 'pyLandau.cpp' via `find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`, you can try to use `exclude_package_data`, or `include-package-data=False` in combination with a more fine grained `package-data` configuration. You can read more about "package data files" on setuptools documentation page: - https://setuptools.pypa.io/en/latest/userguide/datafiles.html [^1]: For Python, any directory (with suitable naming) can be imported, even if it does not contain any `.py` files. On the other hand, currently there is no concept of package data directory, all directories are treated like packages. ******************************************************************************** !! check.warn(importable) creating build/lib.linux-x86_64-cpython-39/pyLandau/cpp copying pyLandau/cpp/pylandau.cpp -> build/lib.linux-x86_64-cpython-39/pyLandau/cpp copying pyLandau/cpp/pylandau.pyx -> build/lib.linux-x86_64-cpython-39/pyLandau/cpp copying pyLandau/cpp/pylandau_src.cpp -> build/lib.linux-x86_64-cpython-39/pyLandau/cpp running build_ext building 'pylandau' extension creating build/temp.linux-x86_64-cpython-39/pyLandau/cpp g++ -Wno-unused-result -Wsign-compare -DDYNAMIC_ANNOTATIONS_ENABLED=1 -DNDEBUG -O2 -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fstack-protector-strong -m64 -march=x86-64-v2 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -D_GNU_SOURCE -fPIC -fwrapv -O2 -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fstack-protector-strong -m64 -march=x86-64-v2 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -D_GNU_SOURCE -fPIC -fwrapv -O2 -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fstack-protector-strong -m64 -march=x86-64-v2 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -D_GNU_SOURCE -fPIC -fwrapv -fPIC -DCYTHON_TRACE=1 -IpyLandau/cpp -I/terabig/nsallin/ndlar_flow.venv/include -I/usr/include/python3.9 -I/tmp/pip-build-env-hq4fm6bt/overlay/lib64/python3.9/site-packages/numpy/_core/include -c pyLandau/cpp/pylandau.cpp -o build/temp.linux-x86_64-cpython-39/pyLandau/cpp/pylandau.o pyLandau/cpp/pylandau.cpp:31:10: fatal error: Python.h: No such file or directory 31 | #include "Python.h" | ^~~~~~~~~~ compilation terminated. error: command '/usr/bin/g++' failed with exit code 1 [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for pylandau Successfully built ndlar_flow adc64format Failed to build pylandau ERROR: Failed to build installable wheels for some pyproject.toml based projects (pylandau)
Solution
The solution was to install pylandau first and then rerun the ndlar_flow install command:
pip install pylandau
and then (in .../ndlar_flow)
pip install -e .
