libc: re-export libc properly #288
Conversation

That is confusing. We just added the We need to figure out how to properly reexport a library in bea/nightly. |
|
Agreed. |

There was a problem hiding this comment.
can you not do
extern crate libc;
pub use libc;
? I think I've done that before...

Ok, I believe what is present now should result in the correct behavior prior to the recent changes coming out of rust-lang/rust#26775 and should also have the same behavior for beta/nightly. |

Looks good here, assuming it works. I'll let @fiveop take another look though. |

☔ The latest upstream changes (presumably #294) made this pull request unmergeable. Please resolve the merge conflicts. |
With rust 1.7, the following warning was being emitted by the compiler:
warning: `pub extern crate` does not work as expected and should
not be used. Likely to become an error. Prefer `extern crate` and
`pub use`.
Based on rust-lang/rust#26775 it appears that
the warning in 1.7 which was to be escalated to an error is going away
but in older versions of rust it is still the case that `pub extern crate`
will not work as expected. Instead, we use a somewhat creative hack to
export the libc root as a module in nix. Down the line, it may make
sense to either eliminate the need to export libc (by chaning the ioctl
macros) or to move toward deprecated older versions of rustc.

Based on rust-lang/rust#26775 it appears that
this change is the current best approach for properly exporting the
libc dependency so it may be used outside of nix.
