Any advice on how to fix this problem?

Windows did not show up any problem and I failed to compile with Linux (Ubuntu).

GitHub now updated with a small change to NavFunc.cpp. Should compile/run ok.

I can confirm that version 1.0 does not compile on linuy while master does...

Would you mind to create a new release to make a released linux version possible? Thanks in advance
