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
|
|
|
13 installed as:
|
|
|
14
|
|
|
15 $LLVM_SRC_ROOT/tools/clang
|
|
|
16
|
|
|
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.

|
22 //===----------------------------------------------------------------------===//
|
|
|
23
|
|
|
24 Configure and build your copy of LLVM (see $LLVM_SRC_ROOT/GettingStarted.html
|
|
|
25 for more information).
|
|
|
26
|
|
|
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.

|
|
|
34
|
|
|
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
|
|
|
37 tests.

|
|
|
41 //===----------------------------------------------------------------------===//
|
|
|
42
|
|
|
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
|
|
|
45 configured.
|
|
|
46
|
|
|
47 The Clang compiler is available as 'clang' and 'clang++'. It supports a gcc like
|
|
|
48 command line interface. See the man page for clang for more information.
