`Unable to find libclang` build error with v0.1.2 #154

Closed Danvil closed 4 months ago

Danvil commented 4 months ago

Everything was working fine with v0.1.1, but then cargo decided to upgrade to v0.1.2 and I get the error below. Forcing the version to v.0.1.1 fixes it:

This is because the 0.1.2 release unintentionally had the feature enabled to regenerate the C bindings which runs bindgen which needs libclang.

This has been fixed on main If you use flecs_ecs via a git dependency, then you'd be fine:

[dependencies]
flecs_ecs = { git = "https://github.com/Indra-db/Flecs-Rust.git", rev = "3d41a15",  version = "0.1.2" }

Fixed on main, should submit a new version soon.
