Compile CP2K on macOS

This page describes how CP2K can be installed under macOS (Monterey, Ventura). This howto has been tested on an Apple M1 under macOS Ventura 13.0.1 (Darwin Kernel Version 22.1.0, Homebrew 3.6.11). For further details check the corresponding Darwin-gnu-arm64 arch file and regression tester. This howto assumes that your default shell is bash.

1. Install Homebrew

Open a Terminal and run the command

/bin/bash -c "$(curl -fsSL"

which will install the latest Homebrew version. This howto was tested with Homebrew 3.6.11.

a) The easy way

If you are only interested in testing CP2K under macOS, then you can install a pre-compiled CP2K binary providing all basic features via

brew install cp2k

using this Homebrew formula. You can ignore the rest of this how-to, in case you are already happy with that CP2K installation.

b) Compile CP2K under macOS from scratch

If you installed CP2K with brew in the previous step, then make sure that you uninstall first cp2k and its dependencies fftw, libxc, openblas, open-mpi, and scalapack before you continue to avoid any interference with these Homebrew packages during the installation of the CP2K toolchain.

Create the following links

ln -s /opt/homebrew/bin/gcc-12 /opt/homebrew/bin/gcc
ln -s /opt/homebrew/bin/g++-12 /opt/homebrew/bin/g++

to make Homebrew's latest gcc and g++ compilers the default instead of the clang versions in /usr/bin.

2. Obtain CP2K

Checkout the latest CP2K version available from the CP2K GitHub repository using

git clone --recursive cp2k

3. Build the CP2K toolchain

Change to the folder cp2k

cd cp2k

and run the command

source arch/Darwin-gnu-arm64.ssmp

to build the toolchain for a serial CP2K executable. Alternatively, you can build the toolchain for an MPI parallelised CP2K executable with

source arch/Darwin-gnu-arm64.psmp

4. Compile CP2K

Check the output from the toolchain build in the previous step and if there is no error, run

make -j ARCH=Darwin-gnu-arm64 VERSION=ssmp


make -j ARCH=Darwin-gnu-arm64 VERSION=psmp

as suggested depending on the selected toolchain build.

5. Test the CP2K executable

You can run a CP2K regression test using

make -j ARCH=Darwin-arm64 VERSION=psmp TESTOPTS+="--mpiranks 2 --ompthreads 2 --maxtasks 12" test

to validate the generated CP2K executable.

Enjoy CP2K under macOS!
