//===----------------------------------------------------------------------===// // Clang Installation Instructions //===----------------------------------------------------------------------===// These instructions describe how to build and install Clang. //===----------------------------------------------------------------------===// // Step 1: Organization //===----------------------------------------------------------------------===// Clang is designed to be built as part of an LLVM build. Assuming that the LLVM source code is located at $LLVM_SRC_ROOT, then the clang source code should be installed as: $LLVM_SRC_ROOT/tools/clang The directory is not required to be called clang, but doing so will allow the LLVM build system to automatically recognize it and build it along with LLVM. //===----------------------------------------------------------------------===// // Step 2: Configure and Build LLVM //===----------------------------------------------------------------------===// Configure and build your copy of LLVM (see $LLVM_SRC_ROOT/GettingStarted.html for more information). Assuming you installed clang at $LLVM_SRC_ROOT/tools/clang then Clang will automatically be built with LLVM. Otherwise, run 'make' in the Clang source directory to build Clang. //===----------------------------------------------------------------------===// // Step 3: (Optional) Verify Your Build //===----------------------------------------------------------------------===// It is a good idea to run the Clang tests to make sure your build works correctly. From inside the Clang build directory, run 'make test' to run the tests. //===----------------------------------------------------------------------===// // Step 4: Install Clang //===----------------------------------------------------------------------===// From inside the Clang build directory, run 'make install' to install the Clang compiler and header files into the prefix directory selected when LLVM was configured. The Clang compiler is available as 'clang' and supports a gcc like command line interface. See the man page for clang (installed into $prefix/share/man/man1) for more information.
