Error code E0455

Some linking kinds are target-specific and not supported on all platforms.

Linking with kind=framework is only supported when targeting macOS, as frameworks are specific to that operating system.

Similarly, kind=raw-dylib is only supported when targeting Windows-like platforms.

Erroneous code example:

ⓘ
#[link(name = "FooCoreServices", kind = "framework")] extern "C" {}
// OS used to compile is Linux for example
Run

To solve this error you can use conditional compilation:

#[cfg_attr(target="macos", link(name = "FooCoreServices", kind = "framework"))]
extern "C" {}
Run

Learn more in the Conditional Compilation section of the Reference.
