Link Issue with mkl_scalapack

yongbei_ma_ — Fri, 14 Oct 2016 21:40:36 GMT

my code(test.cpp) is this:

#include <vector>
#include "mkl_scalapack.h"

void main()

{
   int N = 1000;
   std::vector<int> key(N);
   std::vector<double> value(N);
   for (int i = 0; i < N; i++) {
       key = i+1;
       value = i+1;
   }
   int info;
   char id = 'I';
   dlasrt2(&id,&N,&value[0],&key[0],&info);
}

my build option is this(on OS X 10.11.3 ,mpi version /opt/intel/compilers_and_libraries_2016.2.146/mac/mkl/lib):

$icpc -mkl test.cpp -o test
Undefined symbols for architecture x86_64:
"_dlasrt2", referenced from:
_main in icpcHc4PnE.o
ld: symbol(s) not found for architecture x86_64

my question:

what's the correct option to build this file?

Thanks

pls try -mkl:cluster. -mkl

pls try -mkl:cluster. -mkl option, by default links with SMP libraries.

Now I have to use the LAPACK

Now I have to use the LAPACK instead of SCALPACK, it works....

int info = LAPACKE_dlasrt('I',N,&value[0]);
