I tried running export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu, which changes the error:

This looks like a standard "on a 64-bit platform and forgot 32-bit libraries" kind of error, so I would be wary of calling this a regression from 1.5 to 1.6 without further information.

[skade]

I see this issue when using rustc > 1.6.0 (master) with the rust toolchain for rumpkernel/rumprun-packages. Definitely no 32 bit binaries in path.

triage: P-low

[brson]

@skade Is this still a bug? Looks like OPs issue was resolved.

[skade]

@brson I currently have issues building my rumprun toolchain. I also know of no other users that have this bug. Close it and I will reopen if this persists.

When trying to compile this file (or any other rust program):

fn main() {
    println!("Hello World!");
}

I get:

$ rustc hello.rs
rustc hello.rs --verbose

I'm running 32bit ubuntu:

$ uname -a
Linux tmbb-laptop 3.13.0-98-generic #145-Ubuntu SMP Sat Oct 8 20:13:07 UTC 2016 i686 i686 i686 GNU/Linux

and using rust 1.14:

$ rustc --version
rustc 1.14.0 (e8a012324 2016-12-16)

[tmbb]

For the record, I get the same linking errors with rustc 1.0.0 and some versions I tried between these two.

[tmbb]

It was a problem with my local setup. Consider it fixed.
