C程序常见warning处理 [Warning]defined but not used [-Wunused-function] 定义了一个结构体(静态函数或变量),警示没使用。使用 __attribute__((unused)) 告诉编译器忽略此告警 [Warning] passing argument 1 of 'del' makes pointer from integer without a cast 函数的形参是指针时,传入的形参应该是指针,而...
显示:warning: ‘Func’ defined but not used 警告原因:Func 函数你定义了,但是你根本没有使用它。 解决方法:不要的就去掉。 类型16: 显示:warning: suggest parentheses around && within || 警告原因:有人这么用了if(( *p >= 'a' ) && ( *p <= 'z' ) || ( *p >= 'A' ) && ( *p <= '...
类型1:显⽰:warning: implicit declaration of function 'Example()'。警告原因:在你的.c⽂件中调⽤了函数Example(),可是你并没有把声明这个函数的相应的.h⽂件包含进来。有可能你在⼀个.c⽂件中定义了这个函数体,但并没有在.h中进⾏声明。解决⽅法:你可以在调⽤这种函数的.c⽂件的...
The kernel module works fine but in this case I receive the following warning as a static declaration creates a separated copy on every file in which it is included: warning: ‘gpio’ defined but not used [-Wunused-variable]: static volatile uint32_t *gpio; I've tried to declare it ex...
102: Too much global data defined in file — 文件中全局数据太多103: Two consecutive dots — 两个连续的句点104: Type mismatch in parameter xxx — 参数xxx类型不匹配105: Type mismatch in redeclaration of xxx — xxx重定义的类型不匹配106: Unable to create output file xxx — 无法建立输出文件xxx...
1、‘XXX’declare but never used 变量XXX已定义但从未用过。 2、‘XXX’is assigned a value which is never used 变量XXX已赋值但从未用过。 3、 Code has no effect 程序中含有没有实际作用的代码。 4、Non-portable pointer conversion 不适当的指针转换,可能是在应该使用指针的地方用了一个非0的数值。
这个错误提示说明标签(label)被使用了,但是却没有定义(defined)。在 C 语言中,标签可以用于循环语句、跳转语句等,如:for (i = 0; i < 10; i++) { if (i == 5) { goto endloop;} } endloop:如果使用了一个未定义的标签,编译器就会提示这个错误。解决这个错误的方法是,检查代码...

warning: function function1 is used but not defined. Could you please let me know why i am getting such warning? I would like to transfer all the __inline__ function into the .c so that I won't get the warning: warning: function1 is could not be inlined, code size may grow. ...
