Build fails with version 3.9.x/3.10.x on OpenBSD

[lcheylus]

How are you using the lua-language-server?

NeoVim

Which OS are you using?

OpenBSD current/amd64 (future version 7.6)

What is the issue affecting?

Compilation of luamake

Expected Behaviour

Build of lua-language-server OK with luamake on OpenBSD current/amd64

Actual Behaviour

On OpenBSD current/amd64, build of lua-language-server v3.9.3 KO => unable to build luamake

In version 3.9.3, luamake version/commit = c086f35. This version uses bee.lua version/commit 038aef6. In this version, symbol EVFILT_USER for bee.epoll is unknown on OpenBSD, see actboy168/luamake#41

Reproduction steps

1. Git clone sources for lua-language-server v3.9.3
2. cd 3rd/luamake
3. Build luamake via ./compile/build.sh

=> error: use of undeclared identifier EVFILT_USER

Additional Notes

Please, update version of luamake and bee.lua in third-party modules to remove EVFILT_USER in bee.epoll.

Hey @lcheylus I'm having the exact same issue, but using updated versions of luamake and bee.lua as mentioned in actboy168/luamake#41 didn't help :/

It seems that an attempt to fix this problem was made with 84c18c3, but unfortunately it didn't work out.

Since you managed to build lua-language-server on openbsd, could you please give us some guidance on how to do it as well ?

Hi @IcaroPablo
you could try to build lua-language-server version 3.9.0 on OpenBSD. See my WIP port here => https://github.com/jasperla/openbsd-wip/tree/master/devel/lua-language-server

@lcheylus thank you very much :D I'm gonna check it out right now

@actboy168 Please could you update luamake / bee.lua version to remove use of EVFILT_USER symbols? See actboy168/luamake#41

[CppCXY]

I have created a Rust-based luals port, which might meet your requirements. see https://github.com/LuaLS/lua-language-server-rust

[lcheylus]

@CppCXY Thanks for this info, I will try your LuaLS project based on Rust 👍

After the updates to bee.lua and make.lua, there are significant interface incompatibilities. I currently don't have the time to address these compatibility issues.

Problem fixed with lua-language-server version 3.14.0 on OpenBSD current/amd64 (kernel GENERIC.MP#663 18/05/2025) => EVFILT_USER mandatory to compile luamake (see actboy168/luamake#41) is now supported => see openbsd/src@8f25c06

Build OK for lua-language-server version 3.14.0 on OpenBSD current/amd64

$ sysctl kern.version
