build on PowerPC window.c build error

First off thank you so much for making my favorite file browser for xwindows , open source!
I know you don't support Linux PowerPC and am thankful for any time you give to this question.

I'm on PowerBook G41.5ghz 32bit Ubuntu 12.04 and trying to build marlin from this bzr clone.
I've only had very basic programming classes in college and didn't persue a career in the field and this was long ago.

PowerPC is not supported by various developers for obvious reasons but any ways here is the error that I get when trying to build marlin.

Marlin source code I cloned into /opt/marlin

I did
sudo mkdir build
cd build
sudo cmake .. -DCMAKE_INSTALL_PREFIX=/opt

and
sudo make

and upon doing "sudo make"

I get the folowing error:
