MOAB plugin missing from visit 3.4.1

[iulian787]

MOAB plugin is missing from latest visit build on ubuntu 22, gcc 10
https://github.com/visit-dav/visit/releases/download/v3.4.1/visit3_4_1.linux-x86_64-ubuntu22.tar.gz
I am wondering if there are issues with the build that can't be overcome?

I have a local build of visit 3.4.0 with moab plugin that is fine, on a ubuntu 22 machine, with gcc 11, vtk9, qt6

I don't recall at the moment the problem I encountered building moab for that distro. I will investigate again.

Moab requires lapack, which wasn't installed in the container from which I built the distro.
Do you require a new ubuntu22 tarball before the next release of VisIt?

Thank you Kathleen,
I am more interested in a red hat build, that we used before to install VisIt on a cluster (chrysalis) at Argonne; I understood that there are problems now with opengl / mesa libraries; Our build on that machine was not successful, but we were able to use a tarball,

Thank you

MOAB can be built with either Eigen3 or LAPACK. I guess for the plugin, we aren't really using any local dense systems and I may be able to create an option to disable any dependency on both. Is this desirable to simplify the MOAB plugin availability on all platforms?

[biagas]

@vijaysm that might be helpful, but perhaps other developers more familiar with the MOAB plugin could say for certain.

I created a new ubuntu22 distribution, it contains moab and uintah, if you want to try it out.
It is located with the assets on our releases page and had '--with-uintah-beta' in the name.

I also updated the Dockerfile for Ubuntu22 to install the liblapack-dev pkg so MOAB will build.

[vijaysm]

Thanks so much @biagas I'll try it out and verify that everything works with the MOAB plugin in the new build

[vijaysm]

The build works out of the box in serial/parallel on our Ubuntu22 compute machines! This is quite helpful. There are some minor issues and @markcmiller86 has some notes on them from our discussions today.

@biagas fyi...MOAB is actually still missing in the normal ubuntu 22 asset. However, it does exist in the unitah-beta asset and that is what @vijaysm was referring to.
