Making a python package and cross-platform compatible
Hi Ive been trying for days now and i just cannot work this out.

Can someone please tell me if im doing this right.

I've written some python3.3 code and now i want to transfer it to an embedded computer to execute.

My OS is a : Debian GNU/Linux 6.0.7 (squeezez) 32-bit kernel
Compiler gcc 4.4.4 and gcc 4.4.5


The target computer is : Linux 2.6.9 32bit cpu.
Compiler gcc 3.3.2

So i have the .py files. I install cx_freeze with python3.3.

I then use cxfreese file.py, which create a folder called dist with a bunch of files and a executable.

Now from my understanding everything it needs to run is inside that folder?
So how come when i transfer over to the target computer it says " cannot execute binary file"

is this todo with them haveing diffrent compilers? how do i update the target computers compiler when there is no apt-get or dpkg facility?

Please someone save Smilie

LEARN ABOUT DEBIAN

dh_python

DH_PYTHON(1)							     Debhelper							      DH_PYTHON(1)

NAME

       dh_python - calculates Python dependencies and adds postinst and prerm Python scripts (deprecated)

SYNOPSIS

       dh_python [debhelperoptions] [-n] [-V version] [moduledirs...]

DESCRIPTION

       Note: This program is deprecated. You should use dh_python2 instead.  This program will do nothing if debian/pycompat or a Python-Version
       control file field exists.

       dh_python is a debhelper program that is responsible for generating the ${python:Depends} substitutions and adding them to substvars files.
       It will also add a postinst and a prerm script if required.

       The program will look at Python scripts and modules in your package, and will use this information to generate a dependency on python, with
       the current major version, or on pythonX.Y if your scripts or modules need a specific python version. The dependency will be substituted
       into your package's control file wherever you place the token ${python:Depends}.

       If some modules need to be byte-compiled at install time, appropriate postinst and prerm scripts will be generated. If already byte-
       compiled modules are found, they are removed.

       If you use this program, your package should build-depend on python.

OPTIONS

       module dirs
	   If your package installs Python modules in non-standard directories, you can make dh_python check those directories by passing their
	   names on the command line. By default, it will check /usr/lib/site-python, /usr/lib/$PACKAGE, /usr/share/$PACKAGE,
	   /usr/lib/games/$PACKAGE, /usr/share/games/$PACKAGE and /usr/lib/python?.?/site-packages.

	   Note: only /usr/lib/site-python, /usr/lib/python?.?/site-packages and the extra names on the command line are searched for binary (.so)
	   modules.

       -V version
	   If the .py files your package ships are meant to be used by a specific pythonX.Y version, you can use this option to specify the
	   desired version, such as 2.3. Do not use if you ship modules in /usr/lib/site-python.

       -n, --noscripts
	   Do not modify postinst/prerm scripts.
