• 准备

  • 1）安装python

    sudo apt install python3
    curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py   # 下载安装脚本
    sudo python get-pip.py
    pip3 --version
    pip3 install regex
    pip3 install pyyaml
    

  • 2）下载 PC-lint plus

    git clone https://hub.fastgit.org/shinyathena/PCLint_Plus.git
    cp -rf ./pclintplus1.2.1/ /home/my/tools
    

  • 3. 在linux下设置环境变量PATH，将可执行文件pclp64_linux添加到环境变量PATH中。

    vi ?/.bashrc
    export PATH=$PATH:/home/my/tools/pclintplus1.2.1  // 添加这一行，其中 /home/my/tools/pclintplus1.2.1 是你自己的路径
    

• 步骤

  // 生成 co-gcc.lnt
  cd /home/my/tools/pclintplus1.2.1/config
  python3 pclp_config.py --compiler=gcc --config-output-lnt-file=co-gcc.lnt --config-output-header-file=co-gcc.h --generate-compiler-config
  
  // 编译 imposter
  cd /home/my/tools/pclintplus1.2.1/config
  gcc -o imposter imposter.c
  
  // 生成 hello.commands
  export IMPOSTER_LOG=hello.commands
  cd /mnt/d/work/src // Makefile 所在目录
  make -e CC=/home/my/tools/pclintplus1.2.1/config/imposter  AR=/home/my/tools/pclintplus1.2.1/config/imposter
  
  // 生成 hello.lnt 
  cd /mnt/d/work/src/main
  python3 /home/my/tools/pclintplus1.2.1/config/pclp_config.py --compiler=gcc --imposter-file=hello.commands --config-output-lnt-file=hello.lnt --generate-project-config
  
  // 修改 hello.lnt, 添加 arm-linux-gnueabihf-gcc 头文件目录
  cp hello.lnt hello.lnt.backup
  vim hello.lnt
  
  -env_push
  -i"//usr/local/arm-linux-compiler/arm-linux-gnueabihf/libc/usr/include"
  -i"//usr/local/arm-linux-compiler/arm-linux-gnueabihf/libc/usr/lib/include"
  -i"//usr/local/arm-linux-compiler/arm-linux-gnueabihf/include/c++/4.9.3"
  -i"//usr/local/arm-linux-compiler/arm-linux-gnueabihf/include/c++/4.9.3/arm-linux-gnueabihf"
  -i"//usr/local/arm-linux-compiler/lib/gcc/arm-linux-gnueabihf/4.9.3/include"
  -i"/mnt/d/work/work/system/inc"
  -fcu
  "src/*.c"  // 这里修改为 lint 所有 .c 文件
  -env_pop
  
  // 静态代码检查
  cp /home/my/tools/pclintplus1.2.1/config/co-* ./
  pclp64_linux co-gcc.lnt hello.lnt  > warning-out.c
