c - 是否可以禁用外部库的 MISRA 检查？

Question

是否可以禁用外部库的 MISRA 检查？我已经尝试过这个，但它似乎不起作用(此 header 使用 C++ 风格的注释和不兼容的 @ 标签)。

#pragma ghs startnomisra
#include <qcarcam.h>
#pragma ghs endnomisra

2018 年 10 月 4 日更新:最小示例

#pragma ghs startnomisra
#include <INTEGRITY.h>
#include <unistd.h>
#include <stdlib.h>
#pragma ghs endnomisra


int main(void)
{
    const char* msg = "Hello world";
    write(1, msg, strlen(msg));
    Exit(0);
}

编译器输出:AFAIU 这些行与 #pragmas 包含的包含相关

Answer 1

您可以通过将 --misra_2004=none(或 --misra_2012=none)添加到相关项目文件(例如， :

图书馆:

#!gbuild
[Library]
    -object_dir=$__OUT_DIR
    -o $__OUT_DIR/lib/libfoo.a
    --misra_2004=none

程序中的单个文件:

#!gbuild
[Program]
:
src/foo/bar.c
    --misra_2004=none

我不知道为什么，但这对于包括 INTEGRITY.h 在内的所有内容都是必要的。
