This is the official repository of the xtb program package developed by the Grimme group in Bonn.

Extended Tight Binding

Installation

Build Status

Statically linked binaries (Intel Compiler) can be found at the latest release page, a version for Linux (Intel 18.0.2, GLIBC 2.19) and Windows (Intel 2022) is provided. The xtb program and library are packaged on conda-forge for Linux (x86_64, aarch64, ppc64le) and MacOS (x86_64, arm64). For homebrew users a custom tap is available at grimme-lab/homebrew-qc providing prebuilt MacOS/x86_64 binaries, for MacOS/arm64 binaries will be compiled on installation automatically.

Bleeding edge releases (Linux only) of the latest source from this repository are available on the continuous release tag.

This projects supports two build systems, meson and CMake. A short guide on the usage of each is given here, follow the linked instructions for a more detailed information (meson guide, CMake guide).

Compilers: 1. ifort(<=2021.10.0), icc(<=2021.10.0) 2. gfortran, gcc 3. ifx, icx (some versions may not work)

Meson

Using meson as build system requires you to install a fairly new version like 0.62 or newer (except 1.8.0). To use the default backend of meson you have to install ninja version 1.7 or newer.

bash export FC=ifort CC=icc meson setup build --buildtype release --optimization 2 -Dfortran_link_args="-qopenmp" ninja -C build test

[!IMPORTANT] Compilation with meson on macOS differs slightly from the protocol for Linux-based systems. Different BLAS libraries can lead to deviating results in rare cases – please stick to the following instructions.

Setting up meson on macOS #### Compiling with meson on macOS 1. **Use Homebrew for Package Management**: Install dependencies like `gcc`, `gfortran`, and `openblas` using Homebrew. [Further information](https://brew.sh/) on how to setup `brew`. Example: ```bash brew install gcc gfortran openblas ``` 2. **meson setup call with appropriate environment variables**: Use the following adapted `meson setup` call to compile `xtb` on macOS. Obviously, the paths to the libraries might differ on your system. ```bash LDFLAGS="-L/opt/homebrew/opt/openblas/lib" CPPFLAGS="-I/opt/homebrew/opt/openblas/include" FC=gfortran-14 CC=gcc-14 meson setup _build --buildtype release -Dlapack=openblas ```


Make sure the testsuite is running without errors.

To install the xtb binaries to /usr/local use (might require sudo)

bash ninja -C build install

For more information on the build with meson see the instructions here.

CMake

The CMake build system requires both make and CMake to be installed, the latter has to be version 3.9 or newer.

Building xtb with CMake works with the following chain of commands:

bash cmake -B build -DCMAKE_BUILD_TYPE=Release make -C build make -C build test

To install the xtb binaries to /usr/local use (might require sudo)

bash make -C build install

For more detailed information on the build with CMake see the instructions here.

Conda

Conda Version

Installing xtb from the conda-forge channel can be achieved by adding conda-forge to your channels with:

conda config --add channels conda-forge

Once the conda-forge channel has been enabled, xtb can be installed with:

conda install xtb

It is possible to list all of the versions of xtb available on your platform with:

conda search xtb --channel conda-forge

Contributors

We are developing this program to make our research possible. Many of the features that xtb has today have been added because there was a dire need for them and we had many contributors who made these features reality:
