Lammps comilation error

Dear Lammps Community,

I complier the version of Dec 15 with gcc, and there is no problem

For some reason, our engineer reset the default from gcc to intel

Then a compilation problem coming (also with the version of 16Feb16)
when compiling the compute_hexorder_atom.cpp

I have check the list email, and don’t konw what you mean

so, I have to question

1)I want to confirm that it is our complier too old?

2)can I ingore the this cpp to compile the project?

It would be more useful to have an error message of the compiler error. That way we can see what causes the problems and might be able to deduce if it is a compiler version problem or something else.

If you can switch the default compiler from intel to gcc, that would of course also solve the problem.
