[GtkGLExt] DLLs and requirements

[Toby Roworth <webmaster orkyden co uk>]

I've been trying to build my application against GtkGlExtmm , and am 
encountering linker errors when I compile, despite adding the 
-Wl,--enable-runtime-pseudo-reloc option as suggested.

I am using MinGW and MSys on 32bit Vista ( :-( ) and compiling with the 
following command, with the required DLLs in the appropriate directory

g++ -Wl,--enable-runtime-pseudo-reloc source/OpenDisplay.cpp -lsqlite3 
-lgtkg
lextmm -lgdkglextmm -o OpenDisplay.exe `pkg-config gtkmm-2.4 --cflags 
--libs` `
pkg-config --cflags gtkglextmm-1.2`

However, I still get the following errors:

Info: resolving __ZTVN3Gtk2GL11DrawingAreaE by linking to

undefined reference to `OpenDisplayGlArea::~OpenDisplayGlArea()'

Am I putting the extra argument in the wrong place (I've tried many 
permutations), do I need annother DLL or is something else wrong. (Note 
I renamed the DLLs)
