Hi,

You need a C++ compiler on your system, e.g.

Dear Gromacs users,

I got a list of errors after running "cmake ..". I am sure the "cmake"
itself is already installed. I am installing Gromacs 5.1.4 on
ubuntu-14.04.1 on VMwarePlayer on a Dell PC. Can I ask how to solve this?


Thank you.

Yours sincerely

Cheng
