Evolution STEllaire en Rotation (Ester) is a 2d stellar evolution code. This repo provides a script to build a C++/Fortran/Python development environment to compile and execute ester using the Nix ecosystem.
The only requirement is Nix itself. Install Nix following the instructions at https://nixos.org/download/.
Alternatively, you can use one-liner for installing Determinate Nix
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install --determinate
Test your installation by running
nix --version
which should return something like nix (Nix) 2.24.1.
Clone or download this repo. Then open a terminal, navigate to the root of this repository and execute
nix develop --extra-experimental-features nix-command --extra-experimental-features flakes
This will instantiate the development environment and compile Ester's evolution branch. Upon finishing, you will be in a bash shell with the following commands available: star1d, star2d, star_evol.
The lock file in this directory guarantees a consistent development environment, greatly facilitating the installation of ester across different distributions
-The build has been tested in Ubuntu, Arch Linux, Rocky Linux, MacOS(M1) and in Windows through the WSL
