Cannot test dylib

[MarkSwanson]

Cargo will create DSOs and compile src/bin/*rs files just fine (which also run fine).

However, Cargo is unable to compile/run test programs for crates that have [lib] crate-type = ["dylib"].

I can not add rlib - if I do then any dependent crates will only link statically - and they MUST link this crate dynamically.

I tried to craft my own rustc, but it seems the thing blocking me is '--test'.

Is there any way at all to write tests against crates with crate-type = ["dylib"] ?

Thanks.

I think this may actually be a bug in the compiler right now. To be clear, you're talking about a tests/*.rs test and a crate which is a dylib?

[MarkSwanson]

Yes, exactly.

Would it help if I logged a bug with rustc and referenced this issue?

Oh sure yeah, I opened up an issue here -- rust-lang/rust#34909

Sounds like this issue has been replaced by the rust-lang/rust issue rust-lang/rust#34909 so I'm closing this one. Please reopen if there's a cargo component that needs to be changed once that issue is fixed that I'm missing. Thanks!
