I am now using Cython compiler to wrap a C-language program which needs OpenMP with setup.py script as follows (the Cython script "test.pyx" imports "test.h" module).
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
ext_modules = [
Extension("wrap_test",
["test.pyx"],
libraries=["gomp"],
extra_compile_args=["-fopenmp"])]
setup(
name="wrap_test",
cmdclass={"build_ext": build_ext},
ext_modules=ext_modules)
This is for gcc. Then, what is the Intel compiler (icc) counterpart? Does anyone know the answer?
If I just set the environmental variable CC to icc and type "python setup.py build_ext --inplace", then several error messages appear and gcc is automatically invoked in stead of icc (to link object files). This results in a shared object "wrap_test.so", which cannot be imported to other Python scripts due to some mistakes. So I guess I have to tell Cython a proper set of a compiler, libraries and compile options to use in the setup.py script.
