[petsc-dev] CMake on Catalina

[Satish Balay]

I just did the following build on 3 of the OSX test boxes. [with brew gcc etc..]

balay at jpro^~/petsc(maint) $ ./configure --with-mpi=0 CC=gcc-9 CXX=g++-9 FC=gfortran-9 --download-cmake

Worked on 2 of them.

The 3rd failed with PETSc configure errors.

As far as I can tell - all 3 systems should be the same [latest, OSX, xcode updated at the same time, all have command line tools installed etc..] - but they are not  - and I don't understand why.
