Build fails with musl

[globin]

In make install I get:

How did you configure the build? Also can you gist a full output?

[asaaki]

I guess I have a similar problem. At least I get the same error message.

I tried to follow your instructions at #24777, but stumbled upon an issue:

Clone and build LLVM's libcxxabi library. Only the libunwind.a artifact is needed. I have tried using upstream libunwind's source repo but I have not gotten unwinding to work with it unfortunately. Move libunwind.a adjacent to MUSL's libc.a

I followed the instruction of libcxxabi, but got no libunwind.a at all (tried with trunk and the 3.6.2 release tag from svn).
So I went for the libunwind by pathscale and got the artifact.
But building rust with this in place results in the error mentioned above.

You can find my build steps at https://gist.github.com/asaaki/e15fb009ba4b40611d78

Would be awesome if you could provide more detailed instructions on how to reproduce a successful build.

@asaaki, there are also new instructions at:
https://github.com/rust-lang/rust/blob/master/src/doc/trpl/advanced-linking.md

I've successfully build rust-must using them.

[asaaki]

Okay, will try this. Thanks for the pointer.

[asaaki]

Status update so far:
It seems it is possible to build against the current master branch only right now.
And if I interpret the version string correctly, then this will be later the 1.3.0 release.

Thank you again for the hint, @tailhook!

[tailhook]

@asaaki, well, let me know if you manage to build something using cargo which has "libc" as dependency (many packages depend on libc somewhere in the chain). That's where I currently am :)

[aidanhs]

(the above is possible with libc crate >= 0.1.10 per rust-lang/libc#15)

[alexcrichton]

Ah yeah I believe that this was fixed some time ago on master, so closing.
