Cross compiling a python script on windows into linux executable
Tendou,
Since I usually develop on a Linux machine, when I need a windows version I often use cx_freeze to make windows binaries, but I also used it to make Linux binaries and it works pretty well (it is multiplatform, something py2exe is not). Like Eli said above, it doesn't really compile, but just bundles the interpreter, byte compiled code and needed libraries into an executable, but you'll get what you want (running on a machine without python pre-installed).
After having installed cx_freeze on a Linux machine, you can try it out with something simple, like this dummy code, which i saved as test.py:
import time
for i in range(10):
print i
time.sleep(1)
Then run cxfreeze to make the binary. The output will look like this:
$ cxfreeze test.py

Note that with bigger projects you might get "Missing modules" errors. If you are sure they are installed, you can manually point them to cx_freeze using the --include-modules switch. See cxfreeze --help for the full help.
You can also make a setup.py file which makes "cxfreezing" resemble the way we usually install python packages, instead of doing it directly from the command line. This article even does that for a wxPython project, which might be similar to yours:

Cross-compiling in Python in Windows TO Linux/OSX
Code obfuscation is really not 'pythonic'. Even when packed into an .exe file, it's basically just the python interpreter and you source code (well, the .pyc files) zipped into one file. It is not as much as cross-compiling as it is about using a python package which does the thing you want (e.g, pack you code in a specific way) on linux.
Freeze will do this for you.Most linux dists come with python built-in.
Get your linux box running! It's fun, useful, and you can always say 'On My Machine It Works!'. You can compile your code there / test your exe on Wine.
If for some reason you still can't get it to run, post a question!
Packaging a Python script on Linux into a Windows executable
Did you look at PyInstaller?
It seems that versions through 1.4 support cross-compilation (support was removed in 1.5+). See this answer for how to do it with PyInstaller 1.5+ under Wine.
Documentation says:
Add support for cross-compilation: PyInstaller is now able to build Windows executables when running under Linux. See documentation for more details.
I didn't try it myself.
I hope it helps
