Build requirements

[rhn]

What are the necessary development tools?

Naively building on Fedora 24 with just libappindicator-gtk3-devel results in error:

$ rustc --version
rustc 1.17.0 (56124baa9 2017-04-24)

$ cargo run
   Compiling libappindicator-sys v0.1.1

I am getting the same error on Xubuntu 18.04

Sorry, I forgot what I did to solve it. I don't remember being angry over it, so it's definitely some package in the standard repos.

FYI, I bumped into it as well.
Problem was I installed libclang*.
sudo apt-get install clang solved it for me.
