building

mkdir build
cd build
cmake ..
make
make install
sudo ldconfig

ensure that all references to gr_phil are gone from /usr/local/lib The ldconfig command sometimes moves symlinks to .so files around. Somtimes running make install after sudo ldconfig fixes things.

test install

python -c "import gr_phil; print(gr_phil.symbol_bert(8,(1,1j,-1,-1j)))"
