[Numpy-discussion] building numpy with python3.7

[Hannes Breytenbach]

Hi devs!

This is my first post to the discussion list!

Has anyone tried to build numpy with python3.7.0a3? 

I get the following gcc errors during compile:

    .
    .
    .
    
    compiling C sources
    C compiler: gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC

Version info:
-------------
gcc --version: gcc (Ubuntu 6.3.0-12ubuntu2) 6.3.0 2017040
numpy version: 1.15.0.dev0+d233e1f


The same error comes up when building via pip.  I don't know enough about the underlying C code to know how to debug this. Any help would be greatly appreciated!

Cheers,
