I'd like to use boost::compute and boost::range together, like below, but if I uncomment the '#include ' line I get an error saying that boost::compute::zip_iterator and boost::iterators::zip_iterator are ambiguous. Is there a way around this, so that I can use boost::compute and boost::range together in the same cpp file? I am using on Windows vs2015 64bit. Boost 1.67.0.
Code:
#include <vector>
#include <iostream>
#include <algorithm>
//#include
#include
#include
#include
#include
namespace compute = boost::compute;
using compute::float4_;
using compute::lambda::_1;
using compute::lambda::_2;
using compute::lambda::distance;
int main()
{
// get default device and setup context
compute::device device = compute::system::default_device();
compute::context context(device);
compute::command_queue queue(context, device);
// generate random data on the host
std::vector a(10000);
std::vector b(10000);
std::vector<float> r(10000);
std::generate((float*)a.data(), (float*)(a.data() + a.size()), rand);
std::generate((float*)b.data(), (float*)(b.data() + b.size()), rand);
// create a vector on the device
compute::vector _a(a.size(), context);
compute::vector _b(b.size(), context);
compute::vector<float> _r(r.size(), context);
// transfer data from the host to the device
compute::copy(a.begin(), a.end(), _a.begin(), queue);
compute::copy(b.begin(), b.end(), _b.begin(), queue);
boost::compute::transform(
_a.begin(), _a.end(),
_b.begin(),
_r.begin(),
distance(_1, _2),
queue
);
// copy values back to the host
compute::copy(_r.begin(), _r.end(), r.begin(), queue);
for (int i = 0; i < a.size(); ++i)
{
float4_ va = a[i];
float4_ vb = b[i];
float vr = r[i];
float e = std::sqrt(std::pow(va[0] - vb[0], 2) +
std::pow(va[1] - vb[1], 2) +
std::pow(va[2] - vb[2], 2) +
std::pow(va[3] - vb[3], 2));
std::cout << std::setprecision(12);
if (std::abs(e - vr) > 1e-2)
std::cout << e << " != " << vr << "\n";
}
return 0;
}
Error, truncated for brevity. I can post the full error log if it is helpful:
