// 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 'clang++'. It supports a gcc like
|
|
command line interface. See the man page for clang (installed into
|
|
$prefix/share/man/man1) for more information.
