Building with icc failes

[dschwoerer]

I have been trying to build with icc, but that failes as for the linking of the so, gcc is used instead.

Other extensions seem to work fine.
You can reproduce this issue as well without an extra compiler:

CC=echo CXX=echo python3 setup.py build_ext

I have tested other extensions, and they use echo for compiling and linking, whereas cftime uses it only for compiling, and gcc for linking.

This issue is present in master, as well as cftime-1.0.0 from pypi.

Can you point to one that works with your echo test? Looking over the setup.py, I don't see anything that looks wrong. It seems to just be using setuptools.

I thought it would be working for netcdf4-python, but that came apparently pre-compiled :-/

It is working for me in boutcore:

I noticed boutcore is using distutils.core rather then setuptools
I guess I should report this to setuptools ...

LDSHARED needs to be set to change the linker from gcc to icc.

Thanks, setting LDSHARED resolves the issue.
Would really be nice if that would be documented ...
