clang is a great compiler, with a boatload of extremely helpful tools, including static analysis, run-time memory and data race analysis, and many others. And it’s apparently pretty easy to get those benefits on one of the supported platforms – basically Ubuntu and Mac (via XCode).
That’s fine, but if you get paid to write software, there’s a good chance it’s going to be deployed on RedHat, or one of its variants. And, getting clang working on RedHat is a huge pain in the neck. The good news is that I did the dirty work for you (ouch!), so you don’t have to.
