Target x86-64-v2 to allow Hapi to run on older HW

[viblo]

What feature would you like to see?

I have a home server, with a quite old CPU. Hapi cant start on it since it seems to be compiled with a too new CPU architecture as target.

The binary refuse to start with "Illegal instruction (core dumped)" on this machine.

I suspect it might be because Hapi targets x86-64-v3, but my server only supports x86-64-v2 (which basically is the various SSE versions but no AVX or later instructions).

Does it need to target these, or would it work equally good to target x86-64-v2?

I realize that it would make it somewhat less optimized for those with a more modern CPU, but I would have thought that Hapi wouldnt be very performance sensitive since much of the work is by OpenCode/Codex/Claude and ultimately the LLMs?

Repo build script only selects platform+arch (bun-<platform>-<arch>). No x86-64-v2/v3 CPU feature target found in repo build scripts. So no repo-level switch for v2/v3 in current code.

Relevant code:

• cli/scripts/build-executable.ts:5 - default targets include bun-linux-x64 only (platform+arch)
• cli/scripts/build-executable.ts:12 - supported arches limited to x64 and arm64
• cli/scripts/build-executable.ts:182 - build uses bun build --compile --target=...

Need more info:

• HAPI version or release tag used
• Exact artifact name (single-exe vs CLI package)
• OS distro + kernel version
• CPU model + lscpu flags

After sleeping on this Im not sure if you want to retarget the main distribution. Maybe its enough that its possible to recompile with the bun version that supports the v2 target.
