是否可以禁用外部库的 MISRA 检查？我已经尝试过了，但它似乎不起作用（此标头使用 C++ 样式注释和不兼容的 @ 标记）。

#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

解决方案#pragma diag_suppress=tag[,tag,...]还可用于抑制来自 MISRA C 检查器的消息。

为避免您必须为每个 #include 编写一长串 MISRA C 标记，您可以使用以下两个宏：

#define MISRAC_DISABLE _Pragma ("diag_suppress= \

要禁用 MISRA C 检查头文件，您可以编写...

MISRAC_DISABLE
#include "myincludes.h"
MISRAC_ENABLE

--misra_2004=none您可以通过添加（或--misra_2012=none）到相关项目文件来禁用每个库单元或每个文件的 MISRA 检查，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.

简单的答案是：这取决于您的工具链——但我希望如此。

通常，您可以配置它将检查哪些头文件 - 例如，可以将 LDRA ToolSuite 配置为检查项目头文件 ( #include "xxx.h")，但不能在系统头文件中 ( #include <xxx.h>)

静态分析选项 --> 包括搜索 --> 不展开

更新：注意到 GreenHills 标签...我相信会有类似的东西

注意：请参阅从属关系的简介！
