本文解释了编译警告LNK4089的原因，即程序中声明了使用GDI库但并未实际调用相关函数导致链接器移除所有对GDI32.dll的引用。

LINK : warning LNK4089: all references to "GDI32.dll" discarded by /OPT:REF

The warning means that your program contains functions that call GDI, but the functions are never called, so the link to GDI is never actually used. For exmaple, this program will raise the
warning:

void CallGDI()
{
GetStockObject(WHITE_BRUSH);
}

int main(int argc, char**argv)
{
// notice that this function never calls the CallGDI function
return 1;
}

The linker is saying, "Um, you wrote some functions that use GDI, but you never called those functions, so I'm not sure what you're trying to do here."
