RoboWare Please install [clang](http://clang.llvm.org/) or check configuration `clang.executable`

This error message is shown every time when I click on my cpp source file. And I have already installed clang3.8 using apt-get, but the problem is still there.

@nickhuan , which version of roboware are you using? When execute "clang -v" in terminal, what is the output?

The version I'm using is 0.4.2: "Version 0.4.2 Commit 71c238851d88c4aaa2853cc7768678ead4b1a96c Date 2017-02-28T01:50:02.302Z Shell 1.4.6 Renderer 53.0.2785.143 Node 6.5.0" in About

I get following when I execute "clang -v": The program 'clang' can be found in the following packages:

clang-3.3
clang-3.4
clang-3.5 Try: sudo apt-get install

@nickhuan , clang is not installed properly, try "sudo apt-get install clang" to install clang. After installation, execute "clang -v'', the following outputs indicate that clang is successfully installed:

clang version 3.9.0 (tags/RELEASE_390/final) Target: x86_64-unknown-linux-gnu ...

The system requires me to install clang-3.4 and I think it works fine now. Thanks!
