Hi, everyone!

I’m using my apple silicon MBP to build LAMMPS. After cmake configuration, there is a fatal error i occur:

/Users/roy/lammps/src/lmptype.h:34:2: error: LAMMPS requires a C++11 (or later) compliant compiler. Enable C++11 compatibility or upgrade the compiler.
#error LAMMPS requires a C++11 (or later) compliant compiler. Enable C++11 compatibility or upgrade the compiler.

using enable_if_t = typename std::enable_if<B, T>::type;

So how to set up -std=c++11 in cmake, or use clang to compile LAMMPS. Does M1 processor’s compatibility leads to this error?

Thanks in advanced!

There is a bunch of information missing to give specific advice.

Which LAMMPS version is this with?

What are the exact commands you used?

Please also provide the output of the cmake command to the screen.

Thanks,
Axel.

P. S. : in the future please send emails with a meaningful subject line.
