OS X Framework support

[ashgti]

Currently, I do not see any way of linking against a native framework in OS X. For instance, if you wanted to link against OpenGL on OS X, it currently fails to find the native library.

Its possible to just create .o files and link them but it would be nice if there was some way for this to work with the rust compiler.

One possibility could be to add a #[framework_name = "OpenGL"] attribute to the native mod, similar to #[link_name].

You can work around this via #[link_args]. See how rust-cocoa does it: https://github.com/pcwalton/rust-cocoa

(Update from pnkfelix: link above is dead, but I think this is suitable replacement: https://github.com/pcwalton/rust-core-foundation/ e.g. data.rs )

[metajack]

Since framework names are quite platform specific, one suggestion might be to use this syntax:

#[link_name="OpenGL.framework"]

and have rustc do the right thing on OS X and fail on other platforms.

Here's a more specific example of how this is currently done: https://github.com/mozilla-servo/rust-core-foundation/blob/master/base.rs#L151
