Dear Robert,
after installed the required dependencies, then build Elomal, I have run the Python install script:

$ sudo python3 setup.py install

Thank you for help, best, Philippe

I'm not sure if this is due to a difference in your gcc version or in Cython, but I can't reproduce it. The fix I just commited should replace the fprintf call with a safer fputc, but please re-open in case the same problem appears elsewhere.
