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: 1>------ Build started: Project: demo, Configuration: Debug x64 ------ 1> demo.cpp 1> This header is implementation detail and provided for backwards compatibility. 1>C:\local\boost_1_67_0\boost/compute/algorithm/transform.hpp(67): error C2668: 'boost::compute::make_zip_iterator': ambiguous call to overloaded function 1> C:\local\boost_1_67_0\boost/compute/iterator/zip_iterator.hpp(276): note: could be 'boost::compute::zip_iterator,boost::compute::buffer_iterator,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type>> boost::compute::make_zip_iterator,boost::compute::buffer_iterator,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type>>(IteratorTuple)' 1> with 1> [ Thanks, Madison
