Compilation failure on OpenBSD-current

[ron-at-swgy]

Summary

When attempting to build the v5.0 tag, I encounter compilation errors for implicit instantiation of undefined template zmm_vector<unsigned long>. I first encountered this issue while trying to pip install numpy for numpy >= 2.0.0. The trail has led me here :)

Environment information

    (.venv) host$ uname -a
    OpenBSD host 7.5 GENERIC.MP#95 amd64
    (.venv) host$ for suff in vendor id feature; do sysctl machdep.cpu${suff} ; done
    machdep.cpuvendor=GenuineIntel
    machdep.cpuid=0x306c3
    machdep.cpufeature=0xbffbfbff
    (.venv) host$ meson --version
    1.4.1
    (.venv) host$ which cc
    /usr/bin/cc
    (.venv) host$ cc --version
    OpenBSD clang version 16.0.6
    Target: amd64-unknown-openbsd7.5

Steps to reproduce

  $ git clone --depth=1 --branch v5.0 https://github.com/intel/x86-simd-sort.git
  $ cd x86-simd-sort/
  
  $  meson setup --buildtype release builddir && cd builddir

Thanks for reporting this @ron-at-swgy. I don't see this build error when building with clang++-16 locally on ubuntu though. Is there a specific docker container for openBSD I can use to reproduce this? Also, could you try this on main branch and let me know if you see the same error?

[ron-at-swgy]

I suspect the problem is related to types used on the platform. I recently had to submit a PR to a project using SWIG to generate python bindings that corrected the assumptions about type sizes. I’ll look into getting you access to a test environment.

that's my suspicion too. It might need a fix like this:

x86-simd-sort/src/avx2-64bit-qsort.hpp

Line 416 in 33a4a1d

struct avx2_vector<size_t> : public avx2_vector<uint64_t> {

Merged into numpy, closing this.
