isfinite() call is ambiguous on Windows DPC++

AJIOB — Thu, 24 Mar 2022 10:34:11 GMT

Hello

I'm using Intel oneAPI 2022.1.3 (w_BaseKit_p_2022.1.3.210_offline) with VisualStudio 2022 17.0.7 LTS on Windows 10 21H1 Pro x64 English.

I generated vector-add sample & it compiles successfully.

I added that 2 rows for getting finite detection on constant vector in file vector-add-buffers.cpp:

vec<float, 3> test_finite(0.1f, 0.2f, 0.3f); auto is_finite_vec = isfinite(test_finite);

That code was added in h.parallel_for section (lines 85-88 in file vector-add-buffers.cpp).

Nothing else was changed.

But in compiling time I received an error: call to 'isfinite' is ambiguous

Example project & full logs were attached (from VisualStudio command-line & from usual Windows CMD).

How can I fix that?

With regards,
Alex

P.S. Linux DPC++ compiler (Ubuntu 20.04) works correctly & successfully compiled that code. Compiler's version:

$ dpcpp --version Intel(R) oneAPI DPC++/C++ Compiler 2022.0.0 (2022.0.0.20211123) Target: x86_64-unknown-linux-gnu Thread model: posix InstalledDir: /opt/intel/oneapi/compiler/2022.0.2/linux/bin-llvm

Hi,

Thanks for reaching out to us.

Could you please try changing the line

vec<int, 3> is_finite_vec = isfinite(test_finite);

vec<int, 3> is_finite_vec = sycl::isfinite(test_finite);

so that isfinite will de defined from sycl scope.

Hope the provided information helps in resolving your issue.

Thanks & Regards,

Noorjahan.
