get the following error:
undefined reference to `_WinMain@16'
Any ideas what is going on?

This error indicates that you don't have a "main" function in your program.
Looking at your command line, it looks like the "-c" option is missing --
check the "compiler" --> "misc" --> "other flags" box in the build
properties. By default it should contain "-c".
