undefined refrence to oneapi::mkl::vm::cdfnorminv

Niko_ — Thu, 30 Sep 2021 15:20:29 GMT

I'm trying to calculate element-wise inverse cumulative normal distribution function of a vector using the cdfnorminv function in MKL. For this i have written the following short program:

#include <CL/sycl.hpp> #include <algorithm> #include <sys/time.h> #include <stdio.h> #include "mkl.h" #include "oneapi/mkl/vm.hpp" #include <iostream> using namespace sycl; #define RAND_NO 10 int main(){ std::cout<<"Start"; queue device{ gpu_selector{} }; double *h_random1 = malloc_shared<double>(RAND_NO+1, device); double *h_random2 = malloc_shared<double>(RAND_NO+1, device); device.submit([&](handler &h){ h.parallel_for(RAND_NO, [=](id<1> i){ h_random1[i] = (i[0]+1.0)/(RAND_NO+1.0); }); }); oneapi::mkl::vm::cdfnorminv(device, RAND_NO, h_random1, h_random2); std::cout<<"The numbers generated on the host are :\n "; for(int i=0; i<RAND_NO; i++) { std::cout<< h_random1[i]<<'\n'; } free(h_random1); free(h_random2); return 0; }

However when I try to compile it i get the following error:

undefined reference to `oneapi::mkl::vm::cdfnorminv(cl::sycl::queue&, long, double*, double*, std::vector<cl::sycl::event, std::allocator<cl::sycl::event> > const&, oneapi::mkl::vm::enums::mode, oneapi::mkl::vm::detail::error_handler<double>)'
dpcpp: error: linker command failed with exit code 1 (use -v to see invocation)

Other parts of MKL work fine (rng for example) so I am having a difficult time figuring out this fails to work.

Mikola,

please follow with MKL Linker adviser (https://software.intel.com/content/www/us/en/develop/tools/oneapi/components/onemkl/link-line-advisor.html) suggests and you will able to build this example like as follows:
