Update notes about static linking and MUSL #224
Conversation
People often use the edition guide as general documentation of capabilities, not just for Rust 2018. There is extensive information on the web suggesting that Rust *only* supports static linking with MUSL. Add a note documenting current capabilities, so that people know they have a choice of libc implementations even if they need static linking.

Thanks @joshtriplett ! Just so you know, the current state of the edition RFC would be to remove the vast majority of the edition guide, and until that RFC is merged, I've effectively stopped work here entirely. |

@steveklabnik That's fair, but until that change happens, I've seen people use and cite the edition guide as a reference for the capabilities of Rust. I don't mind if this text ends up deleted later to make way for something else. Would you consider merging it in the interim? |
|
I think we shouldn't just remove the information -- I would like to see it put elsewhere (maybe something like a "Feature List" or whatever, not sure on naming), but regardless I agree that merging this in the interim makes sense to me. The reason we are thinking of dropping it from the Edition Guide in particular is that people were confused about whether the features were tied to a particular edition or not, I believe. |

There was a problem hiding this comment.
Are you sure it is 1.48? I thought static support is in 1.49 (rust-lang/rust#77386).
I would suggest being a little clearer here, and providing an example:

| [crt-static]: ../../../reference/linkage.html#static-and-dynamic-c-runtimes |
I would also put this at the bottom of this section (just before ## Installing MUSL support).

I'm fine with minor updates until the fate of the guide is determined. Also, in the future I would like to see platform-specific documentation added to the |

Ping @joshtriplett Are you still interested in this? |
