5 These instructions describe how to build and install Clang.
7 //===----------------------------------------------------------------------===//
8 // Step 1: Organization
9 //===----------------------------------------------------------------------===//
11 Clang is designed to be built as part of an LLVM build. Assuming that the LLVM
12 source code is located at $LLVM_SRC_ROOT, then the clang source code should be
15 $LLVM_SRC_ROOT/tools/clang
17 The directory is not required to be called clang, but doing so will allow the
18 LLVM build system to automatically recognize it and build it along with LLVM.
20 //===----------------------------------------------------------------------===//
21 // Step 2: Configure and Build LLVM
22 //===----------------------------------------------------------------------===//
24 Configure and build your copy of LLVM (see $LLVM_SRC_ROOT/GettingStarted.html
25 for more information).
27 Assuming you installed clang at $LLVM_SRC_ROOT/tools/clang then Clang will
28 automatically be built with LLVM. Otherwise, run 'make' in the Clang source
29 directory to build Clang.
31 //===----------------------------------------------------------------------===//
32 // Step 3: (Optional) Verify Your Build
33 //===----------------------------------------------------------------------===//
35 It is a good idea to run the Clang tests to make sure your build works
36 correctly. From inside the Clang build directory, run 'make test' to run the

40 // Step 4: Install Clang
41 //===----------------------------------------------------------------------===//
43 From inside the Clang build directory, run 'make install' to install the Clang
44 compiler and header files into the prefix directory selected when LLVM was
47 The Clang compiler is available as 'clang' and supports a gcc like command line
48 interface. See the man page for clang (installed into $prefix/share/man/man1)
