Jeff, here are my personal notes for building on joule. They are pretty similar to my ubuntu install instructions. So someone pointed out that a dependency (I think boost) didn’t work anymore; you just need to bump that up to the latest version on their site. Also, as mentioned in the last user meeting, there is a problem w/ the latest hypre. You might be able to get a newer version than whatever I point to here (back when Joule3 came online), but don’t use the latest release. (Unless that’s been fixed that I’m unaware of.)
