Hi,

I am trying to compile cylib module however I am getting error,

This is the modifications i did in my build.sh

rm cylib.so

cython -a cylib.pyx -o cylib.cc

#gcc -shared -pthread -fPIC -fwrapv -O2 -Wall -fno-strict-aliasing \
#  -I/usr/include/python3.5m -o cylib.so cylib.c
g++ -shared -pthread -fPIC -fwrapv -O3 -Wall -fno-strict-aliasing \
-I/usr/local/lib/python3.7/site-packages/numpy/core/include -I/usr/local/Cellar/python/3.7.2_2/Frameworks/Python.framework/Versions/3.7/include/python3.7m -o cylib.so cylib.cc -std=c++11
#-I/usr/lib/python3.7/site-packages/numpy/core/include -I/usr/include/python3.7m -o cylib.so cylib.cc
  #-I/usr/include/python3.6m -o cylib.so cylib.cc
#g++ -shared -pthread -fopenmp -fPIC -fwrapv -O2 -Wall -fno-strict-aliasing \
#  -I/usr/include/python3.5m -o cylib.so cylib.cc

After compiling its giving a long error

Is it possible if you can update the .so file somewhere for us to download of have you any idea how can I solve this.

Which system are you using? Also, which Numpy version?
