[petsc-users] configuring on OSX

[Brian Van Straalen]

Thanks Barry.  that gets me further.   now it seems the COPTFLAGS are not
being propagated from PETSC to HYPRE.  I have -framework Accelerate in my
COPTFLAGS, but HYPRE still fails looking for BLAS and LAPACK routines.
_dgetri, _dgetrs, and so on.   Or does PETSc, and Hypre, and SUPERLU all
pull in their own blas and lapack source code and this is from me disabling
Fortran?  I can't use Fortran in PETSc since sowing does not work on OSX as
PETSc configures it (claims "configure: error: cannot run C compiled
programs." but I know that is not true.  I suspect sowing has linux-isms
see attached log).

is there some way to have PETSc configure just run through and
*configure *things,
and have a make command *make* things?    I have to keep re-issuing the
configure command, which prevents me from debugging a build errors.   I'm
about two days into this port to OSX....

Brian
