Install Clang in CentOS

Install Clang in CentOS

I. Preparations for environment before installing Clang in CentOS for Minimal

1. install gcc: yum install gcc

2. install g ++: yum install gcc-c ++

3. Install cmake in source code:

The reason for using the source code installation is that the yum default installation version is too low, and Clang has requirements for the cmake version.

Source code: https://cmake.org/download/

Decompress the package and run it in the cmake directory.

1)./bootstrap

2) gmake

3) make install

4) cmake -- version

4. install perl: yum install perl

Since the pod2html command is required during Clang script installation, perl must be installed.

Ii. Clang installation (3.6.0)

1, source code download,: http://llvm.org/releases/download.html

Download the following four files:

2. decompress the four files after the download is complete.

1)clang-tools-extra-3.6.0.src.tar. Unzip the tool and rename it as extra.

2)cfe-3.6.0.src.tar. Unzip the file and rename it clang.

32.16llvm-3.6.0.src.tar. decompress the package and rename it llvm.

4)compiler-rt-3.6.0.src.tar. decompress the package and name it compiler-rt.

Store the four files in the following directory structure:

Compiler-rt is placed under the projects directory under the llvm directory. And so on

3. Clang Installation

1)

1 ./configure--enable-optimized--enable-targets=host-only--prefix=/home/YouPathToInstall/llvm

2) make

3) make install

4) clang -- version

Note: Clang has version requirements for gcc, g ++, cmake, and so on. Try not to install the version too low.
