cppcheck静态扫描代码是否符合MISRA-C 2012规范
1 下载安装cppcheck
1.1 下载安装包
下载地址:http://cppcheck.net/
同时把 Source code (.zip) 也下载下来,后面会用到。
1.2 安装及配置
双击安装文件,保持默认配置安装即可,默认安装的路径为:C:\Program Files\Cppcheck 。
将步骤一下载的 source code.zip解压,将根目录下的 addons 目录拷贝到安装目录。
然后将安装路径添加到系统路径 path 中,方便命令行直接使用命令。
2 创建配置文件
在存放安装包的目录下(其他路径也可以)创建一个misra.json 的文件,内容如下:
{
"script": "misra.py",
"args": [
"--rule-texts=D:/Software/Package/cppcheck/MISRA_C_2012.txt",
"--suppress-rules 17.3,21.12"
]
}
同时准备一个misra-c 2012的规则文件 MISRA_C_2012.txt :

3 运行cppcheck命令
当前目录下准备一个测试用的.c文件main.c:
#include <stdio.h>
int main(void)
{
int buf[5] = {0, 1};
buf[5] = 9;
return 0;
}
执行命令:
注意: --enable=all 参数不能省略。
cppcheck --enable=all --addon=D:/Software/Package/cppcheck/misra.json main.c
将扫描结果输出到xml文件中:
cppcheck --enable=all --addon=D:/Software/Package/cppcheck/misra.json main.c --output-file=test_report.xml --output-format=xml
