是否可以禁用外部库的misra检查?

greenhills misra c

Minor Threat · 技术社区 · 7 年前

是否可以禁用外部库的misra检查?我已经尝试过了,但是它似乎不起作用(这个头使用C++风格的注释和不兼容的@标签)。

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

更新10/4/18: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这些行与包含在pragma中的include相关

您可以通过添加 --misra_2004=none (或) --misra_2012=none )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 .

解决方案这个 #pragma diag_suppress=tag[,tag,...] 也可用于抑制来自misra c检查器的消息。

为了避免这种情况,您必须为每个包括的内容编写一长串misra c标记,您可以使用以下两个宏:

#define MISRAC_DISABLE _Pragma ("diag_suppress= \

要禁用对头文件的misra c检查,可以写入…

MISRAC_DISABLE
#include "myincludes.h"
MISRAC_ENABLE

简单的答案是:这取决于你的工具链——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" )但不在系统标题中( #include <xxx.h> )

静态分析选项-->包含搜索-->不展开

更新:注意到格林希尔标签…我肯定会有类似的东西
