I am doing my master thesis at The University of Linköping (Sweden). Currently Im working on creating a direction field that describes an input mesh. For that I need to solve a linear system and have chosen to use the SuiteSparse QR solver to solve my problem.
I have managed to build SuiteSparse and the SPQR library Im working with in Windows, which both hardly depend on the ACML library. But when I run my code (no compiling errors) it crashes when the SPQR lib makes a call to the dnrm2 function in the ACML library libacml_mp_dll.lib. Ive read this and chosen to use the fortran x64 version. I think Ive tried all of the windows installers but I still get the same error - "Unhandled exception at 0x000007FED30A0B20 (libacml_mp_dll.dll) - Access violation reading location 0x0000000023CAFF00."
The call looks like this:
norm = BLAS_DNRM2 (&N, X, &one) ;
where N and one are integers.
BLAS_NDRM2 is defined as following:
#define BLAS_DNRM2 dnrm2
double BLAS_DNRM2 (BLAS_INT *n, double *X, BLAS_INT *incx) ;
Ive seen other definitions including underscores "_", but if I have understood things correctly it is not the version I want to use in Windows. I've compiled all my libraries in Visual Studio 2012 with the v110 compiler.
Any help would be appreciated, Ive been stuck on this for almost a week now. I'll happily describe the problem in more detail if needed.
