device policy "dpcpp_fpga" not found in namespace

[arnoecho]

I was trying to write a program which intends to utilize FPGA board. According to this page<https://www.intel.com/content/www/us/en/develop/documentation/oneapi-dpcpp-library-guide/top/parallel-api/execution-policies.html>, dpcpp_fpga should be an available policy within namespace <oneapi::dpl::execution>. However, when I compiled the code, I received the following error.

src/api.cpp:31:87: error: no member named 'dpcpp_fpga' in namespace 'oneapi::dpl::execution'
                    auto fut1 = dpl::experimental::fill_async(oneapi::dpl::execution::dpcpp_fpga,dpl::begin(a),dpl::end(a),(1<<31));

I am wondering how to resolve this error.

Hi @arnoecho,

Thank you for posting in Intel community forum and hope all is well.

For us to better understand the situation, it would be a great help if you are able to share the program that you have wrote and also the steps that you taken for the compilation.

Hope to hear from you soon.

Best Wishes

#include <oneapi/dpl/algorithm>
#include <oneapi/dpl/execution>
#include <oneapi/dpl/iterator>
#include <oneapi/dpl/async>
#include <CL/sycl.hpp>
#include <chrono>
int main(int argc, char *argv[]) {
    using namespace oneapi;
    {
        auto policy = oneapi::dpl::execution::dpcpp_fpga;
        ...
        //dpl apis that use the variable <policy> 
        ...
    }
    return 0;
}

Something like this. And when I compile it with

dpcpp -fintelfpga <src> -DFPGA_EMULATOR=1

The compiler reports the following error

error: no member named 'dpcpp_fpga' in namespace 'oneapi::dpl::execution'

Hi @arnoecho,

Thanks for the details explanation and patients.

Based on the error mention my guess is just a missing definition cause the namespace not found.

You may refer to the link below which contain the guide to defined the required namespace based on the oneAPI execution policy.

https://oneapi-src.github.io/oneDPL/parallel_api/execution_policies.html

Hope that clarify.
