What's up with "GetStockObject" ?

Question

I've created a program in Eclipse / MinGW / C (project type: C) which should just present an empty window. It also has the folowing line:

wndclassex.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);

The call to GetStockObject() produces a compiler error:

Z:/mtsts_workspace/MTSTS/Debug/../WinMain.c:29: undefined reference to `GetStockObject@4'

Has anyone an idea what's wrong ?

Answer 1

Check the documentation, and make sure you link to the required libraries (gdi32).

Answer 2

Best guess: you need to link Gdi32.lib.
