Hi,
I am trying to run a code which uses functions from both boost compute
library and arrayfire library. I am getting the following errors when I try
to build the code:
Scanning dependencies of target hello

The code I am using is a very simple helloworld using functions from both
libraries.
#include <iostream>
#include <boost/compute.hpp>
#include <arrayfire.h>
namespace compute = boost::compute;
using namespace af;
int main()
{
// Boost Compute Part
// get the default device
compute::device device = compute::system::default_device();
// print the device's name and platform
std::cout << "hello from " << device.name();
std::cout << " (platform: " << device.platform().name() << ")" <<
std::endl;
// Array Fire Part
std::cout<< "ArrayFire Part:" << std::endl;
af::setDevice(0);
af::info();
return 0;
}
The CMakeList used to build the project is:
cmake_minimum_required(VERSION 3.0)
project(deBruijn_Graph)
find_package(ArrayFire)
add_executable(hello hello.cpp)
target_link_libraries(hello ArrayFire::afopencl)
I do not have a programming background. Please guide me on what I am doing
wrong.
Regards,
Hassan
