@kwabenantim Please could you have a look at #22 to see why it's giving the following error?
make: *** No rule to make target 'pychaste'. Stop.

@bdevans It looks like it might be trying to build from the old PyChaste project repo. Sorry, I should have mentioned that it's currently on the 273-pychaste-merge branch on the main Chaste repo now. Should probably archive the old project once it's merged in.

Thanks @kwabenantim. Building from th 273-pychaste-merge branch gets further but I have now run into this:

To reproduce, clone chaste-docker (git clone git@github.com:Chaste/chaste-docker.git) and run:

MULTI_ARCH_BUILD=false GIT_TAG="273-pychaste-merge" make develop

I got it to install in an ubuntu:jammy container with

pip install --user --no-deps pychaste/package

This should be fine as the dependencies are already manually from apt (mostly)

apt install python3-petsc4py python3-vtk7 python3-xvfbwrapper python3-numpy python3-matplotlib
pip install --user jupyterlab
