Compilation problem with latest master

[vlachoudis]

I am trying to build the latest master v1.2.74 on a latest version of Ubuntu 24.10
and I get multiple errors like

   10 |   this->path = std::move( other.path );
      |   ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~

That is a weird error message. The project should be set to the C++-17 standard so getting a C++-20 related error should not be possible. Can you tell me which compiler and and cmake version you're using so I can see if I can diagnose the problem?

As an alternative, you can also try to use NJOY2016 directly (NJOY21 uses NJOY2016 under the hood): https://github.com/njoy/NJOY2016
The installation procedure for this version of NJOY is essentially the same as what you done for NJOY21 but it will go a lot faster (it only requires a Fortran compiler).

Compiler: gcc version 14.2.0 (Ubuntu 14.2.0-4ubuntu2)
cmake: cmake version 3.30.3

NJOY2016 compiled with no problem
