cc me

See also #17192 which proposes one fix but needs adjustment.

Seeing the same problem on Mavericks (10.9.4)

FWIW, it's possible to work around this by installing gcc and making sure that gcc and cc are aliased to it.

[pnkfelix]

This should be fixed now that PR #17192 has landed.

Feel free to reopen if this is still an issue though!

I ran rustup an hour ago:

rustc 0.12.0-pre-nightly (21d1f4d7c 2014-09-14 10:36:08 +0000)

And I still get:

error: linking with `cc` failed: exit code: 1

clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

error: aborting due to previous error

Possibly the nightly build hasn't got this fix yet?

[thestinger]

It's fixed on master and will be in the next nightly.
