[Gtk-sharp-list] Cannot compile Gtk# 2.8.5 source

Hello listers,

This is my first post here.  I'll explain my situation, while trying not to forget any important details.  Then I'll pose my question.

I am on a project that has many GUIs running on Linux boxes written in Motif.  We are switching everything to Windows and C#.  The look and feel of the GUIs must remain the same.  My task is to find a way to recreate these GUIs in C# with a Motif look and feel.  This led me to GTK#.

Here are the following requirements for our development environment.

Visual Studio 2008



I had good success with the latest version running in VS 2010, 32-bit, but our requirements led me to download v2.8.5 and try to compile.  I'm compiling in the current version of Cygwin and the 64-bit version of GTK+ v2.16.  I opened a "VS2008 x64 Cross Tools" command window to do the compile in.  I currently have to alter the makefiles in the source to run the 64-bit toolchain and also cut out the pkg-config calls as they are not working for me for some reason.

I've been successful in creating the objects until I get to the gtk folder.  I basically am getting linker errors with trying to find many methods starting with "_gtk".  I also tried compiling against v2.22 of GTK+ 64-bit with similar results.  I looked at the required libraries and found the method signatures in gtk-win32-2.0, but without the leading underscore.  So, for example, the linker complains about not finding "_gtk_tree_model_get_type", but the library has "gtk_tree_model_get_type" (no leading underscore).  This confuses me greatly as I cannot find any instances of methods in GTK with leading underscores except ones with a prepended "__impl_gtk_".

Here is my output from the linker:

Here is my makefile for the gtk glue directory:

 rm -f gtksharpglue-2.dll *.o libgtksharpglue-2.a


Notice the CC and DLLWRAP are using 64-bit versions.  I must mention that I tried compiling this in MinGW and didn't even get as far as I have now.

Any help on this problem will be greatly appreciated.
