Barry, thanks, it appears to be working correctly after following your
latest suggestion. I used the following configuration command:
./configure --force --prefix=/opt/libs/petsc COPTFLAGS="-O3"
CXXOPTFLAGS="-O3" FOPTFLAGS="-O3" --with-precision=double
--with-64-bit-indices
Likely you can fix the problem by adding
#if defined(PETSC_HAVE_MKL_INTEL_ILP64)
#define MKL_ILP64
#endif
before the #include in
src/mat/impls/aij/seq/aijmkl/aijmkl.c and
src/mat/impls/baij/seq/baijmkl/baijmkl.c
Please let us know if this resolves the problem.

It is possible they recently added support for using it with 64 bit integers.
You would need to through their documents to see how to get mkl_spblas.h. to
use 64 bit integers and if the library for 64 bit integer has a different name
that would need to be linked to.
You would need to
Hello.
I would like to build PETSc with support for MKL Sparse BLAS, so that
I can use MATAIJMKL for improved performance, but I also need to use
64 bit indices. I'm trying to build using the following parameters:
./configure --force --prefix="/opt/libs/petsc" --with-precision=double
