pism-conda

Repository to build and test PISM conda packages

Installation

Get pism-conda source from GitHub:

git clone git@github.com:pism/pism-conda.git
cd pism-conda

Now create a conda environment named pism-conda. This installs a bare bones environment suitable to build staged-recipes.

conda env create -f environment.yml
conda activate pism-conda

Clone pism/staged-recipes. How can I just checkout pism-channel?

cd ..
mkdir -p pism-staged-recipes
git clone git@github.com:pism/staged-recipes.git . || (git checkout pism-channel && git pull)
cd pism-staged-recipes
pixi install

PISM packages

The pism-channel currently has packages for yaxt, yac, and pism (stable). Change into the recipies/package directory, where package is the package you want to update. Edit the build.sh and meta.yml files.

Updating a package

To bump the version of, e.g., yac, set the new version number in meta.yml:

{% set version = "3.7.0" %}

Download the tarball and extract sha256:

openssl sha256 yac-v3.7.0.tar.gz 

Update the sha256 in meta.yml.

Linting

Before building, lint your changes:

pixi run lint

Build locally

Depending on your architecture, run

pixi run build-linux

or

pixi run build-osx

You may need to clean your path first, though

export PATH=/Users/andy/miniforge3/envs/pism-conda/bin:/usr/bin:/bin:/usr/sbin:/sbin
unset PYTHONPATH
unset CONDA_PREFIX

Uploading

anaconda upload build_artifacts/linux-64/*.conda

or

anaconda upload build_artifacts/osx-arm64/*.conda

PISM Dev

Say you want to create a development environment that installs all prerequisites from conda and compiles PISM from sources. Build from main branch

conda env create -f environment-dbg.yml
git clone https://github.com/pism/pism.git
cd pism
CMAKE_BUILD_PARALLEL_LEVEL=8 pip install --no-build-isolation -v .

where N=8 is the number of parallel builds.
