PARDISO linking in a c++ project

Jae_Young_L_ — Mon, 31 Mar 2014 23:25:58 GMT

I have been using MKL PARDISO in C language projects for many years. I works nicely. Recently, I tried to include PARDISO in C++ project. But it does not work. The linker gives a message that PARDISO and omp_get_max_threads are undefined symbols." I included the following libraries: MKL_C, MKL_IA32, MKL_lapack, MKL_solver and libguide40. What am I missing?

Hi Jae Young,Do you have the

Hi Jae Young,

Do you have the clause like #include "mkl.h" in your c++ file? The extern "C" claim are needed when C++ call C function. For example, in mkl_pardiso.h

#ifdef __cplusplus
extern "C" {
#endif /* __cplusplus */

_Mkl_Api(void,PARDISO,(
_MKL_DSS_HANDLE_t,   _INTEGER_t *,     _INTEGER_t *,
_INTEGER_t *,           _INTEGER_t *,     _INTEGER_t *,
void *, _INTEGER_t *,     _INTEGER_t *,
_INTEGER_t *,           _INTEGER_t *,     _INTEGER_t *,
_INTEGER_t *,           void *, void *,
   _INTEGER_t *))

#ifdef __cplusplus
}
#endif /* __cplusplus */

(irrelevant to the topic, just comments: i i noticed you are using mkl_c, libguide40, are you using some previous MKL version? Here is MKL 11.1.2 release noteshttp://software.intel.com/en-us/articles/intel-mkl-111-release-notes )
