| gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0
That should be good enough.

I am fairly certain that the (accidental ?) mishap of mixing current R,
i.e. his 4.1.2, with a 3.5.1 library is the issue.
It has been so long since I converted from pre-4.0.* that I forgot what the
error message looks like but the arcanae one in David's post may qualify.

| I see openblas in your sessionInfo(). Could that be a problem?
I do not think. Stable interface, unchanged for decades, hot-swappable.
