缺少头文件包含:如果led_init函数定义在一个头文件中,而该头文件没有被包含在主文件main.c中,编译器就会发出隐式声明警告。 函数声明位置不正确:在函数被调用之前,需要有一个相应的函数声明。如果声明在调用之后,编译器在解析调用时无法找到相应的声明。 拼写或命名错误:可能是函数声明或调用时拼写错误,导致编译器...

Then, change your definition of placement new and delete to use this type as the second argument instead of size_t. You'll also need to update the calls to placement new to pass the new type (for example, by using static_cast<my_type> to convert from the integer value) and update th...
C# compiling error: 'System.Array' does not contain a definition for 'Select' and no extension method 'Select' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?) C# Console App - Can't retrieve SOAP 1.2 response...
class.copy.ctor paragraph 6, which says: "If the class definition does not explicitly declare a copy constructor, a nonexplicit one is declared implicitly. If the class definition declares a move constructor or move assignment operator, the implicitly declared copy constructor is defined as deleted...
该函数没有在本文件包含的头文件中定义,而只在其他c文件的头文件中有定义,也就是间接地有定义。 我遇到的: .c文件里调用一个宏EEPROM_ERROR 而宏定义在头文件.h里,使用了printf函数,使用这个函数时需要include <stdio.h> 文件。如果没有包含,就会报上面的错。 解决: 在头文件里include <stdio.h>;发布...
用IAR打开一个之前建立的工程,程序是可以正常工作的,但是现在想在main.c之外的.c文件(如LED.c)里建立新的函数,也在同名的.h文件里声名了该函数,但是在main主函数里调用就会出现declared implicitly,除非在main.c文件里再次声明;为什么会这样? 然后试了下把LED.c的旧的函数改了一下名字,也是会出现declared implic...
If you double click the error/warning message, it will take you to the file and line where the problem is (super handy)!Note that if you see a message that looks like this:Then what you actually have is a linker error. The relevant parts are The message The files causing it (change ...
