Hi Matt:

I have managed to figure out an installation procedure using Debian Linux that installs Larch for all users on the system to use. If this is useful for you , I can write it up.

Yes - I think that would be very helpful. I know that it's all pretty focused on "install for an individual user", so if installing to a server needs modifications, that would be interesting to either automate or at least document. For sure, we're trying to get to "normal pip install-able", but wxPython on Linuxes makes that kind of challenging. Somewhat related: I did verify that the Linux installer works for me, but I built it on a Centos7 machine and installed it on a Centos8 machine, so that might not be a fair test. And I believe that some of the ESRF folks had some trouble with debian and an earlier version of this installer. --Matt

Hi Matt:

My installation is a mix of Debian packages and pip3 installations. This allows for more recent packages that are not in Debian. The trick is to know which ones are needed. I can try the Linux install with one of my virtual Debian machines. That might be helpful.

Yeah, I've been trying to get to the point where pip can be used as much as possible. I think that for Linux, the only real complication (after "basic Python3.7 or later") is wxPython. If there is a Debian package for that (and probably there are packages for the other "core scientific packages" of numpy, scipy, matplotlib, h5py), then I think everything else should be installable with "pip" or a recent Debian package. At least that is the intention. It would be good to test that out in practice too. I have not tried a "root install with python from the OS distribution" on RH/Centos machines either, but it would be good to try that on both RH/Centos and Debian. I think we might even be able to automate some of that testing with Github actions (which defaults to ubuntu). --Matt
