[petsc-users] Segmentation Violation error using SuperLU_DIST in ex 19.c

[Satish Balay]

Do you really need this combination of pkgs?

Matlab is distributed with ILP64 MKL - so it doesn't really work with
LP64 blas/lapack that most external packages require - i.e you can't
really use use matlab and other external-packages.

[also it might not work with complex]

To get a successful matlab build - try:

./configure PETSC_ARCH=arch-linux-matlab --download-mpich --with-matlab-dir=/usr/local/matlab --with-matlab-engine=1 --with-blaslapack-dir=/usr/local/matlab --known-64-bit-blas-indices=1
