Make sure Normaliz 3.1.4 is properly installed (using make install).
If you installed them in a prefix hierarchy other than /usr/local, set environment variables as follows:
export LDFLAGS="-L/SOME/PREFIX/lib -Wl,-rpath,$NORMALIZ_PREFIX/lib $LDFLAGS" export CPATH="/SOME/PREFIX/include:$CPATH"
Then install it using
python setup.py install
or
pip install .
See examples/first.py on how to use it.
