Hello, I'm trying to make binding for LightGBM through their c_api.h (inspired by lightgbm3-rs which have the same issue).
Building the bindings works as expected, but building the tests results in a linking error (see below).
This is only an issue for stable rustc (I'm using 1.78.0), and NOT for 1.80.0-nightly.
Reproduced the issue on ubuntu, debian, pop-os and the rust docker image (debian) with Dockerfile.
I'm using bindgen version 0.69.4 (I've tried older versions back to 0.51)
$ cargo build --tests # cargo test give same error
error: linking with `cc` failed: exit status: 1

Hello, I'm trying to make binding for LightGBM through their c_api.h (inspired by lightgbm3-rs which have the same issue). Building the bindings works as expected, but building the tests results in a linking error (see below).
This is only an issue for stable rustc (I'm using 1.78.0), and NOT for 1.80.0-nightly.
Reproduced the issue on ubuntu, debian, pop-os and the rust docker image (debian) with Dockerfile. I'm using
bindgenversion0.69.4(I've tried older versions back to0.51)My
build.rs:Anyone able can point me in the right direction?
