undefined reference to `TextOutA@20' [duplicate]

Question

I am kind of stuck on this and would appreciate help in solving this please. I am using window GDI, and according to this link, including windows.h is what is needed to work with the TextOut function, among others, but I am still getting some undefined reference error messages and I am stuck.

**undefined reference to `TextOutA@20'|

undefined reference to `CreateDCA@16'|

undefined reference to `Escape@20'|

undefined reference to `DeleteDC@4'|**

    return 0;

Linking to gdi32.lib should solve the problem. :)
