Hi there,

First of all, thank you for all your work on this awesome tool. I managed to get this project compile on NixOS with Intel Ultra Series 2 chip(Omnibook Ultra Flip 14") with all the following conditions, however -DGGML_SYCL=ON fails on OneAPI Toolkit 2025.2:

Working targets:

# I can compile with openvino encoder:
cmake -B build -DWHISPER_SDL2=ON -DWHISPER_OPENVINO=1 -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx
cmake --build build -j --config Release # works

# I can compile with old -DWHISPER_SYSCL which today gives me warnings and doesnt do SYCL anymore(please update documentation)
cmake -B build -DWHISPER_SYCL=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx
cmake --build build -j --config Release # works, but without SYCL

# this one also works, but without SYCL environment as I mentioned, so inference is very slow on my laptop:
cmake -B build -DWHISPER_SDL2=ON -DWHISPER_OPENVINO=1 -DWHISPER_SYCL=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx
cmake --build build -j --config Release # works, but without SYCL

Since I get no SYCL runtime with -DWHISPER_SYCL=ON anymore, I run with -DGGML_SYCL=ON and get these compilation errors:

  • Is there anyway today to surpress these compile time errors with a flag or a change in cmake?

  • Effectively SYCL today seems incompatible with Intel OneAPI Toolkit 2025.2, which version would be compatible?

  • We need to update the documentation with -DGGML_SYCL=ON instead of -DWHISPER_SYCL=ON.

I can share my very advanced flake.nix on demand, if there is any interest. Basically since OneAPI Toolkit is NOT on nixpkgs I download and compiled that manually but everything else is sourced from my custom flake.nix that probably has many cruft that can be removed once I can get this to compile properly: https://gist.github.com/izelnakri/0bc950338081d9177467757d98158e19
