Compilation Failed

[ksurya]

I am getting the following error while building the library. Would you mind looking into this?

[kernc]

The error is your /opt/pgi/linux86-64/16.10/bin/pgcc compiler doesn't know about listed unknown switches (pgcc-Error-Unknown switch: ... lines). If this is a *Ubuntu system, install packages build-essential and/or gcc after which gcc might become the default system compiler. 🤞

Trying to build this package for Nix (python3.7). C++ compilation fails. See reproducible build at https://github.com/NixOS/nixpkgs/pull/78868

Looks like this C++ file has gotten out of date with the underlying CPython libraries.

NOTE: Fixed this issue by removing the .cpp file. Will submit a PR requesting that to be removed. Proper format is to cythonize the .pyx file at setup time, which guarantees that the .cpp file matches the CPython version.

This PR is still not merged. Meanwhile, just execute before build:
