<div dir="ltr"><div>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). <br></div><div><br></div><div>is there some way to have PETSc configure just run through and <i>configure </i>things, and have a make command <i>make</i> 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.... <br></div><div><br></div><div>Brian</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Sep 3, 2019 at 9:35 PM Smith, Barry F. <<a href="mailto:bsmith@mcs.anl.gov">bsmith@mcs.anl.gov</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>
Ahh, the --download-c2html is not needed; it is used only when building all of the PETSc documentation including html versions of the source.<br>
<br>
For some reason it's configure is not doing a good job of selecting cpp. Over the years it has been amazingly portable, I guess Apple just went a bit too far.<br>
<br>
Anyways just run without that option,<br>
