1.添加clang源
deb http://llvm.org/apt/precise/ llvm-toolchain-precise main deb-src http://llvm.org/apt/precise/ llvm-toolchain-precise main # 3.4 deb http://llvm.org/apt/precise/ llvm-toolchain-precise-3.4 main deb-src http://llvm.org/apt/precise/ llvm-toolchain-precise-3.4 main # 3.5 deb http://llvm.org/apt/precise/ llvm-toolchain-precise-3.5 main deb-src http://llvm.org/apt/precise/ llvm-toolchain-precise-3.5 main # Common deb http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu precise main
2.添加共钥
gpg --keyserver wwwkeys.pgp.net --recv-keys 1E9377A2BA9EF27F gpg --export -a 1E9377A2BA9EF27F > /tmp/key sudo apt-key add /tmp/key
3.更新源
sudo apt-get update
4.安装
apt-get install clang-3.4 lldb-3.4 apt-get install clang-3.4 clang-3.4-doc libclang-common-3.4-dev libclang-3.4-devlibclang1-3.4 libclang1-3.4-dbg libllvm-3.4-ocaml-dev libllvm3.4 libllvm3.4-dbg lldb-3.4 llvm-3.4 llvm-3.4-dev llvm-3.4-doc llvm-3.4-examples llvm-3.4-runtime clang-modernize-3.4 clang-format-3.4 python-clang-3.4 lldb-3.4-dev
5.完成
