MinGW can't find my windows API libraries [message #557878]

The below little test project demonstrates my problem. MinGW/cdt/Eclipse... well the linker, can't find the windows API libraries for *most* windows API functions (see CreateFontIndirect and DeleteObject below) whereas some function calls work fine (see MessageBox below)

I looked up CreateFontIndirect and DeleteObject functions in the MSDN library where it say the library needed is gdi32.lib. But if I search my eclipse\mingw directory I only find C:\devtools\eclipse\mingw\lib\libgdi32.a I'm not sure if that is the problem - - if I need to install more windows API libraries than what came with mingw wascana installation?

Any suggestions or comments would be very much appreciated. thanks

Well, you need to tell the linker to link to the needed libraries. From the screenshot I suppose you are using the Makefiles createy by Eclipse. Then have a look here http://wiki.eclipse.org/CDT/User/FAQ#Adding_C.2FC.2B.2B_Exte rnal_Libraries how to do this.
