This gist shows how to build NuPIC Core binaries for release 0.2.7.
cd $NUPIC_CORE
git checkout 0.2.7
git clean -dfx
mkdir -p build/scripts
cd build/scripts
cmake $NUPIC_CORE -DCMAKE_INSTALL_PREFIX=../release -DPY_EXTENSIONS_DIR=$NUPIC_CORE/bindings/py/nupic/bindings
make -j6 install
cd $NUPIC_CORE
python setup.py bdist_wheel bdist_egg
They should be in $NUPIC_CORE/bindings/py/dist
. There should be a wheel and an egg.
