I finally managed to build a 64-bit version of Inkscape 0.48.4 on Windows. I am pretty excited about the build. :)

My build environment is Windows 7 64-bit, mingw-gcc 4.8.1 building x86_64-w64-mingw32 packages.  

One big problem I am having is that some of the icons on the application are missing! I checked all the bug reports and only see a similar issue with Ubuntu Unity.

I am convinced the problem is with the path that Inkscape is seeing. When I divert all stdout to file, I see the following:

was not found either, perhaps you need to install it.

Clearly something with the path where Inkscape is looking for its bits is messed up.

Can anyone help? If you need more information, please let me know.

Everything is working otherwise!

Thanks in advance,
