ubuntu安装符号执行引擎KLEE

背景：ubuntu20.04上安装klee2.2

官网安装教程：KLEE2-2安装教程（不是很详细，仅参考）

本文的安装环境全部放在/opt/klee_env下，root用户下执行命令

1.安装必备工具和依赖

sudo apt-get install build-essential curl libcap-dev git cmake libncurses5-dev python-minimal python-pip unzip libtcmalloc-minimal4 libgoogle-perftools-dev libsqlite3-dev doxygen
sudo apt-get install python3 python3-pip gcc-multilib g++-multilib
sudo pip3 install lit tabulate wllvm
sudo apt-get install zlib1g-dev

2.安装LLVM9

对于版本在18.04以上的Ubuntu，可以直接使用包管理器安装LLVM套件 
sudo apt-get install clang-9 llvm-9 llvm-9-dev llvm-9-tools

3.安装约束求解器z3（时间有点长）

git clone https://github.com/Z3Prover/z3.git 
cd z3/ 
python scripts/mk_make.py 
sudo make install

4.安装uClibc 和 POSIX 环境（建议安装）

如果想使用 KLEE 来运行实际程序，将需要启用 KLEE POSIX 运行时，它构建在uClibc C 库之上。毕竟针对实际程序还是有用的

git clone https://github.com/klee/klee-uclibc.git 
cd klee-uclibc /configure --make-llvm-lib --with-llvm-config /usr/bin/llvm-config-9 
make

5.获取谷歌测试集（可选）

curl -OL https://github.com/google/googletest/archive/release-1.7.0.zip 
unzip release-1.7.0.zip

6.下载klee2-2的代码

下载地址：Releases · klee/klee · GitHub

下载后，解压到/opt/klee_env的路径下

构建 libc++，为了支持C++代码的运行，需要打开对C++标准库的支持

cd klee-2.2
LLVM_VERSION=9 SANITIZER_BUILD= BASE=/opt/klee_env(自己的路径） REQUIRES_RTTI=1 DISABLE_ASSERTIONS=1 ENABLE_DEBUG=0 ENABLE_OPTIMIZED=1 ./scripts/build/build.sh libcxx

7.编译构建klee

安装gcc9（可选）

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update 
sudo apt-get install gcc-9 g++-9

编译

cd klee2-2 
mkdir build
sudo cmake -DENABLE_SOLVER_STP=NO -DENABLE_SOLVER_Z3=ON -DENABLE_POSIX_RUNTIME=ON -DENABLE_KLEE_UCLIBC=ON -DKLEE_LIBCXX_DIR=/opt/klee_env/libc++-install-90/ DKLEE_LIBCXX_INCLUDE_DIR=/opt/klee_env/libc++-install-90/include/c++/v1/ -DENABLE_KLEE_EH_CXX=ON -DKLEE_LIBCXXABI_SRC_DIR=/opt/klee_env/llvm-90/libcxxabi/ -DKLEE_UCLIBC_PATH=/opt/klee_env/klee-uclibc/ -DENABLE_UNIT_TESTS=ON -DENABLE_SYSTEM_TESTS=ON -DGTEST_SRC_DIR=/opt/klee_env/googletest-release-1.7.0/ -DLLVM_CONFIG_BINARY=/usr/bin/llvm-config-9 -DLLVMCC=/usr/bin/clang-9 -DLLVMCXX=/usr/bin/clang++-9 -DCMAKE_C_COMPILER=/usr/bin/gcc -DCMAKE_CXX_COMPILER=/usr/bin/g++ .. 
#没有报错进行最后几步 
make 
sudo make install
 #成功了！！！

8.成功的编译全过程，参考一下，报错什么就比对一下

CMake Deprecation Warning at test/CMakeLists.txt:143 (cmake_policy):
  The OLD behavior for policy CMP0026 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.
