Autotuner Build fails

[chsasank]

Hi,

I have been trying to build autotuner but CMake fails with following error.

Command I used:

cmake -GNinja .. -DSYCL_COMPILER=dpcpp -DDPCPP_SYCL_TARGET=spir64 -DTUNING_TARGET=INTEL_GPU -DCMAKE_BUILD_TYPE=Release

Error:

CMake Error in tools/auto_tuner/CMakeLists.txt:

  in its INTERFACE_INCLUDE_DIRECTORIES.  Possible reasons include:

  * The path was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and references files it does not
  provide.

sycl headers are at /opt/intel/oneapi/2024.0/include/sycl/ in my system.

I got response on discourse (https://support.codeplay.com/t/how-to-build-portblas-for-intel-gpus/667/7) that this is an issue with portBLAS cmake with oneapi changes b/w 2023.x and 2024.x

Hi @chsasank Thank you for your interest in using portBLAS. Could you please try and see if the following changes work for you or not? Thanks.

Side note: clang++ is going to get deprecated soon in the future oneAPI toolkit releases, for more information you can check the README file inside /opt/intel/oneapi/2024.0/bin/compiler/README.txt on your system.

It works with your patch!

I just followed your readme. Happy to make a PR with change to icpx if that's the recommended way to build.

[muhammad-tanvir-1211]

We would rather not update the readme, for now, to change the preferred compiler to icpx instead of clang++. icpx is a closed source release compiler shipped with the oneAPI toolkit, whereas clang++ is available with the nightly releases and when compiling llvm from source. So the preference would still be clang++ as it is opensource.

Hi @chsasank, it looks like we solved this issue. Is it ok to you if I close it? Thank you.

[chsasank]

Sure thanks
