[BUILD ERROR]: v1.32.1 flake patches removed vpux_elf.cmake

[salty-flower]

Summary

The official Nix flake for v1.32.1 fails during patchPhase because it still patches the old third_party/cmake/vpux_elf.cmake path, but the release source tree now uses third_party/cmake/npu_compiler_elf.cmake and third_party/npu_compiler_elf.

Reproduction

nix build github:intel/linux-npu-driver/v1.32.1 --print-build-logs

Actual result

intel-npu-driver> Running phase: patchPhase
intel-npu-driver> substitute(): ERROR: file `third_party/cmake/vpux_elf.cmake` does not exist
error: Cannot build `/nix/store/...-intel-npu-driver.drv`.
       Reason: builder failed with exit code 1.

Expected result

The flake should build the v1.32.1 driver package, or patch the current npu_compiler_elf CMake path instead of the removed vpux_elf path.

Notes

The v1.32.1 release PR changed compiler/submodule-related paths, but flake.nix does not appear to have been updated in the same PR:

• Release PR: NPU Driver 1.32.1 release unified 2026WW12.1 #132
• Current flake still references third_party/cmake/vpux_elf.cmake

The repository tree at v1.32.1 contains:

third_party/cmake/npu_compiler_elf.cmake
third_party/npu_compiler_elf

and not third_party/cmake/vpux_elf.cmake.

Environment

• OS: NixOS x86_64-linux
• Kernel: 6.18.28
• Nix: 2.34.7
• Flake ref: github:intel/linux-npu-driver/v1.32.1

@izelnakri , can you help with it? Or provide any feedback?

[izelnakri]

Yes, I've been having the same issue and avoided using this flake.nix, since it wasn't getting updated. I highly suggest Intel developers/maintainers to use nix and integrate it to the CI process so nix install keeps working with changes within releases and software produced becomes even higher quality.

I'm willing to contribute to this repo and more nix integration across Intel projects, if Intel is willing to hire me on contractual basis.

My team main focus is driver. I am unable to find or hire developer to support nix today
