[TruongKhang]

I got this error. Please help me to fix this:

[txdat]

can you try changing setup.py based on this issue?

[bachan]

I've helped him yesterday @txdat. I also did some updates for the builiding and I think I will do one more update to actually pass compiler flags to python builder from CMAKE (because CMAKE knows platform-dependend flags better). For now he hotfixed it by fixing setup.py in his local copy.

i have same problem @@. Please tell me how to fix issue

[TruongKhang]

specially thank @bachan. @hoangtubatu123 you should change file setup.py to this:

from __future__ import absolute_import, division, print_function`
from Cython.Distutils import build_ext
from distutils.core import setup
from distutils.extension import Extension

import os
os.environ['CC'] = 'g++'
os.environ['CXX'] = 'g++'

ext_modules = [
    Extension(
        name="CocCocTokenizer",
        sources=["CocCocTokenizer.pyx"],
        extra_compile_args=["-Wno-cpp", "-Wno-unused-function", "-O2", "-march=native", '-stdlib=libc++', '-std=c++11'],
        extra_link_args=["-O2", "-march=native", '-stdlib=libc++'],
        language="c++",
        include_dirs=["."],
    )
]

setup(
    name="coccoc-tokenizer", ext_modules=ext_modules, cmdclass={"build_ext": build_ext}
)

Or I see @bachan has changed the building for python. You can try that first

[bachan]

My last patch will still not work on MacOS, so for now just @hoangtubatu123 just use workaround from @TruongKhang, please. :)

I will release the code to pass build options from cmake to python tonight or tomorrow. Then we will test with @TruongKhang's Mac (I don't have a Mac, don't like them haha)

[kewin1807]

yes. thanks you. Bug in mojave version

[kewin1807]

Workaround for me I'm using macOS mojave

• compile project with C++
• fix file setup.py
• cd python && python3 setup.py install --user

[bachan]

I've just added the same workaround into build_python.sh, now you can build using:

$ cmake -DBUILD_PYTHON=1 ..
# make install

README.md is also updated.
