Users of conda (Anaconda, miniconda etc) can install STIR without compilation:

conda create --name stirenv -c conda-forge stir matplotlib
conda activate stirenv

We also (try to) create "developer" versions based on the current master branch. You can install that using for instance

conda install -c conda-forge/label/stir_dev -c conda-forge stir

See the conda-forge doc for more options.

It is recommended to add other packages that you will need at the time of creating the conda environment, as this gives conda the best opportunity to resolve versions.

This should work on Linux, MacOS and Windows. For current status and more details, check the STIR feedstock.
