XIOS 2.5 compiles correctly without specific option with gcc 12 (12.2.0 @ TGCC).
But it seems that you are not using the 2.5 version where meshutil.cpp does not contain vect_points and where earcut.hpp does not exist.

I reproduced your error on the trunk of XIOS 2. Going to C++ 11 using -std=gnu++11 fixed the compilation.

[jderouillat]

For XIOS 2, need to add #include <array> in extern/remap/src/meshutil.cpp.
Commited in ​2398.
