Accumulating complex number using boost compute problem #848

Open ariansharifi opened 4 years ago

ariansharifi commented 4 years ago

this below code face with a compile error, but it is reasonable to accumulate complex number (because I can accumulate complex number using boost compute with boost::transfare_reduce so this should be also reasonable to works with complex numbers)

#include <boost/compute/core.hpp>
#include <boost/compute/platform.hpp>
#include <boost/compute/algorithm.hpp>
#include <boost/compute/types/complex.hpp>
#include <complex>

namespace compute = boost::compute;

int main()
{
compute::vector<std::complex<double_t>> v;
compute::accumulate(v.begin(),v.end(),std::complex<double_t>(0,0));
}

and I face with below compile error
