Both a GCC-compatible compiler driver ( clang ) and an MSVC-compatible compiler driver ( clang-cl.exe ) are provided. You can get and build the source today. Features and Goals Some of the goals for the project include the following: End-User Features : Fast compiles and low memory use Expressive diagnostics ( examples ) GCC compatibility Utility and Applications : Modular library based architecture Support diverse clients (refactoring, static analysis, code generation, etc.) Allow tight integration with IDEs Use the LLVM 'Apache 2' License Internal Design and Implementation : A real-world, production quality compiler A simple and hackable code base A single unified parser for C, Objective C, C++, and Objective C++ Conformance with C/C++/ObjC and their variants Of course this is only a rough outline of the goals and features of Clang. To get a true sense of what it is all about, see the Features section, which breaks each of these down and explains them in more detail. Why? Development of the new front-end was started out of a need for a compiler that allows better diagnostics, better integration with IDEs, a license that is compatible with commercial products, and a nimble compiler that is easy to develop and maintain. All of these were motivations for starting work on a new front-end that could meet these needs. Current Status Clang is considered to be a production quality C, Objective-C, C++ and Objective-C++ compiler when targeting X86-32, X86-64, and ARM (other targets may have caveats, but are usually easy to fix). As example, Clang is used in production to build performance-critical software like Chrome or Firefox. If you are looking for source analysis or source-to-source transformation tools, Clang is probably a great solution for you. Clang supports C++11, C++14 and C++17, please see the C++ status page for more information. Get it and get involved! Start by getting the code, building it, and playing with it . This will show you the sorts of things we can do today and will let you have the "Clang experience" first hand: hopefully it will "resonate" with you. :) Once you've done that, please consider getting involved in the Clang community . The Clang developers include numerous volunteer contributors with a variety of backgrounds. If you're interested in following the development of Clang, signing up for a mailing list is a good way to learn about how the project works....
