开发环境准备

安装构建环境

• 系统环境：arch

• 安装构建运行环境

sudo pacman -S base-devel cmake jinja clang llvm

准备源码环境

git clone -b llvm-10.x https://github.com/heroims/obfuscator

编写构建脚本

#!/bin/sh

build_llvm=`pwd`/build-llvm
build_clang=`pwd`/build-clang
installprefix=`pwd`/install
llvm=`pwd`/obfuscator
mkdir -p $build_llvm
mkdir -p $installprefix

cmake -G Ninja -S $llvm/llvm -B $build_llvm \
      -DLLVM_INSTALL_UTILS=ON \
      -DLLVM_ENABLE_PROJECTS='clang;clang-tools-extra' \
      -DCLANG_INCLUDE_TESTS=ON \
      -DCMAKE_INSTALL_PREFIX=$installprefix \
      -DCMAKE_BUILD_TYPE=Debug

ninja -C $build_llvm install
