[Plib-users] Linking problems with opengl under cygwin

[peter_poulsen <pet...@st...>]

Hi

I'm trying to port my application from Linux to Windows, using Cygwin. =
Unfortunately I get some undefined references I don't understand. Hope =
that some you guys can help me out here.


(the onw*.o and libopen_neverwinter* files are all from my application)
