Thanks for explaining the situation.
So in psi4 1.0 days, we had to rebuild the integrals every time we built Psi4, so I compiled to
MAX_AM_ERI=6. With the new psi4 1.1, integrals are external and so can be compiled once, then nightly builds of Psi4 reuse the same integrals. So the default is now
MAX_AM_ERI=7 (and I might do
8 once I'm satisfied that that's a final compile). Only problem for you is that any binaries that contain
7 also don't contain
PCMSolver. (Also note that you're going to run out of basis sets very soon at these AMs.)
I'm working on Math Lib detection just now, but you're not the only one who's been wanting PCMSolver back lately, so it's up next. Actually, it is possible to build Psi4 with PCMSolver just now, but you have to do some path adjustment yourself. If you like, I can guide you through that. But for an easy sol'n, it'll be a week or two.
