Installation

Prerequisites

One of the goals of the Clang project is to be compatible with GCC, in dialect and on the command-line (see #Differences from GCC). Occasionally some packages will fail to build correctly with it and some may build successfully but segfault when executed. Some packages also have GCC specific code and will also fail during compiling. In these events, GCC will need to be used as a fallback.

USE flags

Some packages are aware of the clang USE flag.

Create a configuration file with a set of environment variables using Portage's built in /etc/portage/env directory. This will override any defaults for any packages that fail to compile with clang. The name used below is just an example, so feel free to choose whatever name is desired for the fallback environment. Be sure to substitute chosen name with the examples used in this article.

The above is the most basic environmental variable needed. You can change it to suit your needs, such as enabling/disabling link-time optimizations, alternative AR, NM, RANLIB, and so on. Here are two examples below:
