Hi,

Thanks for reaching out to us.

We are also able to reproduce the error at our end.

We are working on it internally and will get back to you soon.

Meanwhile, could you please try using -fcoroutines-ts flag as a workaround while compiling with icpx compiler. 

Thanks & Regards

Hello,

Thank you for contacting Intel support.

Here you are trying to use coroutines, which are introduced in C++20.

By the default, Intel oneAPI DPC++/C++ compiler does not enable C++20 features.

If you compile your program as follows, everything would work for you:

icpx -std=c++20 icpxerr6.cpp

Please see the description of -std option here:

https://software.intel.com/content/www/us/en/develop/documentation/oneapi-dpcpp-cpp-compiler-dev-guide-and-reference/top/compiler-reference/compiler-options/compiler-option-details/language-options/std-qstd.html

Regards,

Khalik.

[Khalik_K_Intel · Accepted solution]

As there are no other objections, we consider this thread as being resolved.

Please, enable C++20 features to use coroutines as advised before:

icpx -std=c++20 icpxerr6.cpp

This issue has been resolved and we will no longer respond to this thread. If you require additional assistance from Intel, please start a new thread.

Any further interaction in this thread will be considered community only.
