Install GMP library on Mac OS and PyCharm

Question

I'm trying to run my Cython project. And one of the header is gmpxx.h.

Even though I already installed the gmp library using brew install gmp. I could not run my cython file with python3 setup.py build_ext --inplace.

fatal error: 'gmpxx.h' file not found

#include <gmpxx.h>
         ^~~~~~~~~

1 error generated.
error: command '/usr/bin/clang' failed with exit code 1

So I use brew list gmp to check the location of the gmpxx.h header. So it is actually inside /opt/homebrew/Cellar/gmp/6.3.0/include/ folder.

With Xcode, I can just add the location into the header search paths. But I'm trying to do the same thing with Pycharm. How do I add the location of my gmpxx.h header to pycharm?

I need a little help. Please kindly give me your take. Thank you.

Answer 1

So I added the library location directly into setup.py file.

from setuptools import setup, Extension, find_packages
from Cython.Build import cythonize

extension = Extension(
    "Class Name",
    sources=["Something"
    ],
    include_dirs=[
        "/opt/homebrew/Cellar/gmp/6.3.0/include",  # Include directory for GMP headers
        "/opt/homebrew/Cellar/gmp/6.3.0/include/gmp",  # Additional include directory for GMP headers
    ],
    libraries=["gmpxx", "gmp"],
    library_dirs=[
        "/opt/homebrew/Cellar/gmp/6.3.0/lib",  # Directory containing libgmpxx.dylib
    ],
    extra_compile_args=["-std=c++17", "-O3"],
    language="c++"
)

setup(
    name="Class Name",
    version="0.1",
    packages=find_packages(where="src"),
    package_dir={"": "src"},
    package_data={"Class Name": ["*.pyi"]},
    ext_modules=cythonize(extension,
                          compiler_directives={"language_level":3},
                          annotate=True),
    zip_safe=False
)
