[Mingw-users] Undefined references, any clues?

[Mark J. <mar...@ie...>]

Hi,
I'm trying to compile a program and I'm getting undefined
references errors, but I can't see why, especially for
InitCommonControls(), SetTextColor() and SetBkColor()
etc, as I've linked in gdi32 and comctl32. If I omit the
gdi32 library altogether, I get lots more GDI related uresolved
errors, so that proves the linker is actually using it.

The only error message that seems to make any sense
to me is the one for InitCommonControls(), so I thought
it would be best to concentrate on that one.

I've tried calling InitCommonControls() in another test
program using devcpp instead of on the command line like
here, and that works OK (using the same libraries). So there
must be something about my code that is a problem.

I'm linking a simple program against my own GUI library
called guiw_d.a.

Does anyone have any ideas? Have you seen this before?
Here's my command line invocation and errors:
