octave with enable-64

[Alexander Barth]

Hi all,
I would like to compile octave with --enable-64 to create matrices
larger than 2GB.

Does somebody has experience in compiling BLAS, LAPACK and SuiteSparse
so that this option can be used?

So far I tried to compile the reference BLAS and LAPACK with the
gfortran option -fdefault-integer-8 and SuiteSparse with the option
-DLP64 (I got this from UMFPACK's User Guide). However the example
program in UMFPACK (SuiteSparse/UMFPACK/Demo/umfpack_simple) failed at
the call of dgemv (a BLAS function).

I have the same error with gotoBLAS 1.26 (using BINARY64=1 INTERFACE64=1).

Any insight would be greatly appreciated!

Thanks
Alex
