Hi,
I got Geany to build on Windows XP using the latest SVN. There were some things I needed to change to make the build work. I've attached a patch to show what I changed.
This patch isn't meant to be applied directly, just to show what I needed to do to make Geany build. The main problems were using make escape character \ as a path separator and missing gdk-pixbuf-2.0 include in GTK_INCLUDES.
Now I just need to figure out how to install it :)
Cheers, Matthew Brush
