Software LLVM Requires

This document provides a list of the software packages that LLVM depends on + in order to be built successfully from CVS sources. The requirements for + building from a distribution are fewer. Items only needed for building from a + distribution are noted with an asterisk (*).

The table below shows the required software packages. Package is the usual + name for a given software package that LLVM depends on. Version is a list of + "known to work" versions of the package. Usage describes how LLVM uses the + package.
