I want to build a project that uses various flags by type -O3 -Wall -std=c 11
using cython
, but I get an error:
cl : Command line warning D9002 : ignoring unknown option
Maybe it is possible to replace compilation with VS with Cmake, or am I incorrectly specifying arguments in Windows?.
from setuptools import setup, Extension
from Cython.Build import cythonize
extensions = [
Extension(name=f'{__name__}',
sources=[f'file.pyx'],
language='c ',
extra_compile_args=['-std=c 11', '-O3'],
),
]
setup(name=__name__,
ext_modules=cythonize(extensions),
)
CodePudding user response:
Seems like you are on Windows and use the MSVC compiler. Contrary to gcc and clang, MSVC has no -O3
optimization flag. On MSVC it should either be /Ox
or /O2
, see here for more details.
