Compile bug: SYCL with OneAPI Toolkit 2025.2 & NixOS

[izelnakri]

Git commit

$ git rev-parse HEAD
24e86ca

It is basically version b5377 which is tested to be ok with OneAPI Toolkit 2025.1.1 HOWEVER I have 2025.2 and I CAN'T today download a lower version on the website, the dropdown doesnt work on the intel website. No idea how I can obtain 2025.1.1 and test it against it today.

Operating systems

Linux

GGML backends

SYCL

Problem description & steps to reproduce

I'm running on NixOS with OneAPI 2025.2 manually installed correctly. (I can compile whisper.cpp with it for example using icp and icpx but without SYCL).. I get a compilation error on llama.cpp, just like whisper.cpp on SYCL

I've created a similar issue on whisper.cpp: ggml-org/whisper.cpp#3297

First Bad Commit

No response

Compile command

cmake -B build -DGGML_SYCL=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx
cmake --build build --config Release -j -v

I see you also reported the issue to be able to download older oneAPI versions so thanks.

I tested oneAPI 2025.2 locally on Ubuntu, it works fine. Your error looks like a conflict of macros between the SYCL headers and your glibc version. Would you be able to try and reduce the issue? Are you able to compile a simpler example like vector-add from https://github.com/oneapi-src/oneAPI-samples for instance?

[Rbiessy]

FYI my glibc version is 2.35, I can see yours is glibc-2.40-66-dev. You could maybe try to downgrade your glibc version. If it works with 2.35 it would be worth to report that issue in https://github.com/intel/llvm

@Rbiessy I found a solution here, that probably fixes this one as well: ggml-org/whisper.cpp#3298

I've to admit it is not the most elegant most likely, but a fix is needed on ggml projects side as well(whisper.cpp and llama.cpp) so I can packages these projects for NixOS in the future. Both projects need to be: glibc version(and hopefully icpx version) agnostic so packaging these programs would be possible on NixOS and won't break often.

Currently I source glibc based on what I have at nixpkgs , unstable channel. I could move it to 25.05 channel but I bet it would break the compilation as well. This issue seems very odd to me as the compile time errors makes it seem like its the compiler code error but it seems it can be prevented by certain code/instructions on the project code, so I think this guard must exist in the project code as well, however admittedly could perhaps be more elegant than the C++ code I provided.
