PARDISO linking in a c++ project

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?
