[petsc-users] build with Scalapack/Blacs from MKL (failed to compile a test)

[Satish Balay]

I do not know why this is hapenning. I just tried to reproduce - but it ran fine for me.

balay at es^/scratch/balay/petsc(master=) $ ./configure --with-cc=mpicc.openmpi --with-cxx=mpicxx.openmpi --with-fc=mpif90.openmpi --with-blas-lapack-dir=$MKL_HOME --with-scalapack-include=$MKL_HOME/include --with-scalapack-lib="-L$MKL_HOME/lib/intel64 -lmkl_scalapack_lp64 -lmkl_blacs_openmpi_lp64"


Is this issue reproduceable if you just configure with scalapack [as above?] - and not any other package?

What if you try using --download-openmpi - instead of ubuntu openmpi?

Sorry - I don't have a good answer for this issue..
