从下面的地址下载文件:
http://llvm.org/releases/3.3/llvm-3.3.src.tar.gz
http://llvm.org/releases/3.3/cfe-3.3.src.tar.gz
http://llvm.org/releases/3.3/clang-tools-extra-3.3.src.tar.gz
http://llvm.org/releases/3.3/compiler-rt-3.3.src.tar.gz
http://llvm.org/releases/3.3/libcxx-3.3.src.tar.gz
解压这几个文件,获得:
llvm-3.3.src
cfe-3.3.src
clang-tools-extra-3.3.src
compiler-rt-3.3.src
libcxx-3.3.src
然后在解压内执行
mv cfe-3.3.src clang
mv clang/ llvm-3.3.src/tools/
mv clang-tools-extra-3.3.src extra
mv extra/ llvm-3.3.src/tools/clang/
mv compiler-rt-3.3.src compiler-rt
mv compiler-rt llvm-3.3.src/projects/
然后在建一个目录:
mkdir build-3.3
cd build-3.3
然后编译即可:
../llvm-3.3.src/configure --enable-optimized --enable-targets=host-only
make
sudo make install
完成后用clang++ -v 查看版本即可
