Description Mark Herbert 2024-10-23 02:16:45 UTC

-- Could NOT find SYCL (missing: SYCL_LIBRARY SYCL_INCLUDE_DIR) 
-- Found LevelZero: /usr/lib64/libze_loader.so
CMake Error at build_files/cmake/macros.cmake:1408 (message):
  oneAPI required but not found
Call Stack (most recent call first):
  intern/cycles/cmake/external_libs.cmake:105 (set_and_warn_library_found)
  intern/cycles/CMakeLists.txt:23 (include)


From oneapi deps I see only intel-compute-runtime, and could not find any idea how to get that missing SYCL libs

This may also be related to https://bugs.gentoo.org/882645 (Intel OneAPI support)

Comment 6 Mark Herbert 2024-11-16 17:35:51 UTC

seems that the issue is missing sycl library in gentoo. I've managed to get DPC++ from science overlay merged (outdated package, so was not easy). So seems that a lot of oneAPI is missing in Gentoo... And it is crazy - since that 2022.12 version Intel has split the build into more small packages , they all fetched from git tree based on commit hash during compile time.
