Building from sources
In the absence of prebuilt binaries, LLVM and Clang can be built from scratch by obtaining the source code first. Building the project from the source is a good way to start understanding more about the LLVM structure. Additionally, you will be able to fine-tune the configuration parameters to obtain a customized compiler.
System requirements
An updated list of the LLVM-supported platforms can be found at http://llvm.org/docs/GettingStarted.html#hardware. Also, a comprehensive and updated set of software prerequisites to compile LLVM is described at http://llvm.org/docs/GettingStarted.html#software. In Ubuntu systems, for example, the software dependencies can be resolved with the following command:
$ sudo apt-get install build-essential ...Get Getting Started with LLVM Core Libraries now with the O’Reilly learning platform.
