I've reinstalled MPICH, and did a clean build of p4est, petsc and dealii, this
problem still exists. At the linking stage of building dealii, I got warnings:
[526/579] Linking CXX shared library lib/libdeal_II.9.0.0-pre.dylib
ld: warning: could not create compact unwind for _dgehrd_: stack subq
instruction is too different from dwarf stack size
These are just warnings -- what happens if you run the executable?
The function referenced here is a LAPACK function. It looks like it has been
compiled for a different system than the one you're on. But the error message
you show doesn't give away how this library got onto your system, so I don't
know what to suggest.
