LuaLS
Build fails with version 3.9.x/3.10.x on OpenBSD
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 https://github.com/actboy168/luamake/issues/41
Reproduction steps
- Git clone sources for lua-language-server v3.9.3
cd 3rd/luamake- Build
luamakevia./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 https://github.com/actboy168/luamake/issues/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
Same error with lua-language-server version 3.10.0 :(
Error on OpenBSD current/amd64 when building luamake because of EVFILT_USER used in bee.lua

@actboy168 Please could you update luamake / bee.lua version to remove use of EVFILT_USER symbols? See https://github.com/actboy168/luamake/issues/41
I have created a Rust-based luals port, which might meet your requirements. see https://github.com/LuaLS/lua-language-server-rust
@CppCXY Thanks for this info, I will try your LuaLS project based on Rust :+1:
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 https://github.com/actboy168/luamake/issues/41) is now supported => see https://github.com/openbsd/src/commit/8f25c064c3ea820e7d4347e59ede2a76588208a5
