Unable to use native netlink library from libc crate? #61

Closed donkey-hotei closed 5 years ago

donkey-hotei commented 5 years ago

Attempting to a compile a crate that has a dependency on the netstat library which uses the native netlink API causes a bunch of errors like:

error[E0412]: cannot find type `nlmsghdr` in this scope
error[E0425]: cannot find value `NETLINK_INET_DIAG` in this scope                                                                             
error[E0063]: missing fields `__pad1`, `__pad2` in initializer of `libc::msghdr`

Which leads me to believe that parts of the libc crate are not being linked in correctly? Trying to understand this issue.

As it turns out, musl-libc doesn't define the NETLINK_INET_DIAG and other constants used in the netstat-rs library. This isn't an issue with the builder here but with the crate itself. Closing!
