Build fails on CentOS 7

[robertdebock]

Building on CentOS 7 (with EPEL (Extra Packages for Enterprise Linux) enabled) fails:

   Compiling sudo_plugin-sys v1.1.0 (file:///builddir/build/BUILD/sudo_pair-sudo_pair-v0.9.2/sudo_plugin-sys)

A complete build log for debugging.

I'm not sure how difficult it is to make the build work on CentOS 7, but do think it's worth offering sudo-pair to CentOS-7.

Please let me know if more details are required.

RHEL7 and CentOS 7 have an absolutely ancient version of clang that's not supported by bindgen, one of this project's dependencies. I've already reported this regression upstream, but until I have a chance to fix it upstream this will remain the case.

For reference, clang 6.0 is out, and to get it to build on CentOS 7, you need to install at least clang 3.9.

[robertdebock]

Okay, understood.

[stouset]

Leaving open since it's something I'd eventually like to fix.

[stouset]

Fixed upstream in rust-lang/rust-bindgen#1321. When that gets merged and a new release is cut, this should build cleanly on CentOS 7.

[stouset]

Merged upstream.

[stouset]

This should work now, rust-bindgen has been released. Please let me know!
