I am trying oneAPI from Intel office website: https://www.intel.com/content/www/us/en/develop/documentation/oneapi-programming-guide/top/programming-interface/example-compilation.html

I have completed step 1 “oneAPI Development Environment Setup” and verified it successfully.

In step 2, when I run dpcpp -I${MKLROOT}/include -c axpy.cpp -o axpy.o, it reports several errors:

oneapi/compiler/2022.0.1/linux/bin-llvm/../include/sycl/CL/sycl/bit_cast.hpp:33:22: error: no member named 'is_trivially_copyable' in namespace 'std'

oneapi/compiler/2022.0.1/linux/bin-llvm/../include/sycl/CL/sycl/sycl_span.hpp:164:42: error: no template named 'remove_cv_t' in namespace 'std'; did you mean 'detail::remove_cv_t'

oneapi/compiler/2022.0.1/linux/bin-llvm/../include/sycl/CL/sycl/sycl_span.hpp:187:39: error: no template named 'is_array_v' in namespace 'std'; did you mean 'is_array'

I guess there is some compatibility issue, but I have no idea how to fix. Thanks!

The issue might be with the version of GCC that you have in your system, please check in the system requirements for DPCPP compiler from the below link, intel.com/content/www/us/en/developer/articles/… "Supported minimum versions of distributed libraries that the compilers are built on: GCC - 7.3.0, BINUTILS- 2.30, GLIBC-2.27"

  • Thanks, Vidyalatha. I run "oneapi/sys_check.sh", which prompts "the gcc version found on your path is not 7.4.0...you can point the compiler to that location with the --gcc-toolchain flag". the flag --gcc-toolchain does help me fix this issue. – alephchang Jan 10 '22 at 01:23
