Current version of lang/intel-compute-runtime is outdated - currently latest version is 24.35.30872.22, but in ports we have a version 22.24.23453. Also this ports requires deprecated versions of llvm, but does not have support for llvm18.
It also doesn't work -- crashes immediately when I run a CUDA benchmark.
I don't maintain this anymore but updating requires non-trivial patching to build, drm-kmod < 5.15 to run (see files/patch-userptr) and partially obsolete after ports d8990eff958b. Intel is reluctant to accept FreeBSD patches[1] unless you have a business case[2]. Better ignore Intel official drivers and stick with Rusticl. FreeBSD 13 uses drm-510-kmod where intel-compute-runtime may still work fine. Only llvm11 flavor is supposed to be stable in the current version, see https://github.com/intel/intel-graphics-compiler/blob/igc-1.0.12504.5/documentation/build_ubuntu.md#version-overview [1] VA-API example - https://github.com/intel/media-driver/pull/819 . Instead prefer Vulkan Video which (like Rusticl) is maintained by Mesa where Intel cannot engage in gatekeeping. [2] May be a good task for https://wiki.freebsd.org/EnterpriseWorkingGroup
