[Numpy-discussion] building numpy with python3.7

[Thomas Caswell]

I have been building numpy master with CPython master but am also using
cython master.

My not-pretty script for doing this is:

#! /usr/bin/bash
set -e
TARGET_ENV=bleeding

OSPATH=~/source/other_source/

pushd $OSPATH/cpython/
git pull
git clean -xfd
./configure
make -j 9
./python -m venv --copies --clear ~/.virtualenvs/$TARGET_ENV
popd

source ~/.virtualenvs/$TARGET_ENV/bin/activate

master_build () {
    git checkout master
    git pull
    git clean -xfd
    pip install -v .
}

pushd $OSPATH/cython
master_build
popd
pushd $OSPATH/numpy
master_build
popd
