Question

I am trying to compile the following code but I am getting linker errors. Thankyou to tell what I am missing.

#include <Windows.h>
#pragma comment(lib,"user32.dll")

int main()
{
    return MessageBoxA(0,"Message","Warn",0x01);
}

fatal error LNK1104: cannot open file 'user32.dll'

Answer 1

Since LIB file is used to link against a DLL at compile-time, MessageBoxA resides in user32.dll and requires user32.lib for proper linking.
So change user32.dll to user32.lib in #pragma comment like

#pragma comment(lib,"user32.lib")
