Now that things have begun to settle down, it appears that the autobuilds are beginning to work once again.
The cross-compiler and gtk2.4/gtkmm2.4 libs here: http://troi.titan-aeu.com/~rjamison/inkscape appear to be compiling Inkscape and linking it properly.
You may notice the larger .zip file sizes. This is a result of the unstripped gtkmm .dll files in the distro. I experimented with linking the dll with the static gtkmm libs, then dynlinking the .exe's with that.
The static libs for gtkmm/glibmm, unstripped, are > 120MB!!! So that is not an option for now. Maybe we can think of something else. Stripping is not an option, either. Why cripple the testers' ability to use GDB, the very reason to supply these binaries? However, this -is- development work, so hopefully our testing compatriots can bear with us for a while.
