Ubuntu 18.04 安装Clang/LLVM 11
从 APT 安装
Install the GPG Key for https://apt.llvm.org/
wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
Add the repo for Clang 11 stable-old for Ubuntu 18.04 Bionic
echo "deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic-11 main" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
Install practically everything (except python-clang-11 which for some reason doesn't work)
sudo apt-get install libllvm-11-ocaml-dev libllvm11 llvm-11 llvm-11-dev llvm-11-doc llvm-11-examples llvm-11-runtime \
clang-11 clang-tools-11 clang-11-doc libclang-common-11-dev libclang-11-dev libclang1-11 clang-format-11 clangd-11 \
libfuzzer-11-dev lldb-11 lld-11 libc++-11-dev libc++abi-11-dev libomp-11-dev -y
Make Clang 11 and everything related to it defaults

Installing CMake
Install Kitware's GPG Key
wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | gpg --dearmor - | sudo tee /etc/apt/trusted.gpg.d/kitware.gpg >/dev/null
Add repository
echo "deb https://apt.kitware.com/ubuntu/ bionic main" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
Install this optional package so you don't have to mess with GPG keys anymore
sudo apt-get install kitware-archive-keyring
sudo rm /etc/apt/trusted.gpg.d/kitware.gpg
Now upgrade cmake if you already have it installed with sudo apt-get upgrade -y or just install it using sudo apt-get install cmake -y
使用源码安装
# 更新软件包列表
sudo apt update
# 安装必要的依赖包
sudo apt install build-essential cmake python3-dev
# 下载 Clang/LLVM 11 的源代码
wget https://github.com/llvm/llvm-project/releases/download/llvmorg-11.0.0/llvm-11.0.0.src.tar.xz
# 解压源代码文件
tar xvf llvm-11.0.0.src.tar.xz
# 进入解压后的目录
cd llvm-11.0.0.src
# 创建一个新的目录，用于存放 Clang/LLVM 编译的结果
mkdir build
cd build
# 使用 cmake 编译 Clang/LLVM
cmake ..
# 编译 Clang/LLVM
make
# 安装 Clang/LLVM
sudo make install
