Building building mkl_dfti.h with icpc on MacOSX-10.6

Dear Support Provider

I am trying to build the following code using icpc and MKL library provided with C++ composerxe-2011.4.184 using Xcode.

#include
#include

main (){
complex x[64][64];
int loop = 0;
DFTI_DESCRIPTOR_HANDLE my_desc1_handle;
MKL_LONG status, l[2];

for (int ro = 0; ro<64; ro++)
for (int pe = 0; pe<64; pe++) {
x[ro][pe] = complex (1,1);
loop++;
}
l[0] = 64; l[1] = 64;

status = DftiCreateDescriptor( &my_desc1_handle, DFTI_SINGLE, DFTI_COMPLEX, 2, 1 );
status = DftiCommitDescriptor( my_desc1_handle);
status = DftiComputeForward( my_desc1_handle, x);
status = DftiFreeDescriptor(&my_desc1_handle);
}

It giges the following error with warnig symbols(s) not defined.

Hi,

Please check that variable l[2] of type MKL_LONG is used as the last argument in the following line:
status = DftiCreateDescriptor( &my_desc1_handle, DFTI_SINGLE, DFTI_COMPLEX, 2,l );

Also, correct your linking line using Intel MKL Link Line Advisor
