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.
