Travis: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.18' not found

First of: Thanks for this great work. It makes it soo much faster to setup cross compiled and general auto-publishing with Rust! Thanks so much.

Coming to the problem. Some of our dependencies, somewhere deeper down depend on the backtrace and that doesn't compile in the travis setup :( . I've already tried installing other libc6 bindings but I can't find any way to fix this.

   Compiling backtrace v0.3.0

Build failed, waiting for other jobs to finish...

error: failed to run custom build command for `backtrace v0.3.0`

process didn't exit successfully: `/target/release/build/backtrace-e882241ff52c7727/build-script-build` (exit code: 1)

--- stderr

/target/release/build/backtrace-e882241ff52c7727/build-script-build: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.18' not found (required by /target/release/build/backtrace-e882241ff52c7727/build-script-build)

Full Travis log and the Travis config file used to come to this. I appreciate any input/hints/ideas!

Try removing dist: trusty from your .travis.yml. Maybe that causes other things to fail, but it's worth a try. :)

@johannhof been there - same issue.

I think I found "the problem". So cross uses docker images internally to build for the targets, right? Well, it looks like x86_64-unknown-linux-gnu only supports libc 2.15.

Which is reported there accordingly, so I'll close this here.
