I am trying to link an object file that uses two methods declared in winuser.h and defined in User32.dll: GetMonitorInfo and WindowFromMonitor. The source compiles to the object file just fine, but when I try to link, I get the following error output:
D3dCtx.obj : error LNK2001: unresolved external symbol xGetMonitorInfo
D3dCtx.obj : error LNK2001: unresolved external symbol xMonitorFromWindow
The fact is that I do not call "xGetMonitorInfo" or "xMonitorFromWindow". Running grep on all source files shows that only "GetMonitorInfo" and "WindowFromMonitor" are called. I correctly enable windows.h, which includes winuser.h. I also set LIBPATH correctly in the linker settings, as evidenced by the detailed output of the links.
My verbose link output also shows the following:
