I ran cargo test for bindgen and many of tests pass there:

test result: FAILED. 449 passed; 11 failed; 0 ignored; 0 measured; 0 filtered out

from clang-rs.

I think the reason the clang-sys tests work but the clang-rs tests do not is because one is using runtime linking and the other is not. I believe running cargo test --features runtime in clang-sys would produce the same issue as dynamic linking at compiletime instead of at runtime is the default when no features are provided.

That being said, I'm not sure why this error is being thrown. Running Clang::new should validate that the instance of libclang is loaded. I will look into why this is happening (it works on my Windows 10 machine with Clang 7.0).

Hi Kyle,

I tried the runtime feature is this what I get. Seems to still work. I will try clang 7 for clang-rs.

I installed Clang 7. I still get the same error:
