Switching Compilers (Intel Related) #4518
Description
Hello all, I have an intel-compiled version of Python 2.7.8 that I'm trying to build and install Matplotlib into. When I run "python setup.py build" everything builds fine until:
icc -pthread -fno-strict-aliasing -O3 -fPIC -fp-model strict -fomit-frame-pointer -DNDEBUG -g -O3 -Wall -fPIC -DMPL_DEVNULL=/dev/null -DPY_ARRAY_UNIQUE_SYMBOL=MPL_matplotlib__qhull_ARRAY_API -DNPY_NO_DEPRECATED_API=NPY_1_7_API_VERSION -I/usr/local/python2/2.7.8/x86_64/intel14/nonet/lib/python2.7/site-packages/numpy/core/include -I/usr/local/include -I/usr/include -I. -Iextern -I/usr/local/python2/2.7.8/x86_64/intel14/nonet/include/python2.7 -c src/qhull_wrap.c -o build/temp.linux-x86_64-2.7/src/qhull_wrap.o

compilation aborted for src/qhull_wrap.c (code 2)
error: command 'icc' failed with exit status 2The issue here is that icc does not support templates. When I manually run this command with icpc rather than icc it compiles fine. Can someone advise me on how I can go about switching to icpc to compile qhull_wrap.c? I'm also happy to submit a pull request if this is something that can be generalized in the build process. Version info listed below.
