Hello Lie,
Thanks for your advices.
To have correct updates from ITs is really a true pain. The network
is worldwide in our company. I found issues having decent version.
On my local workstation I have Python v1.5, on compute farm LSF
machines sometimes 2.2 , 2.3, 2.6. That's why I don't want to rely
on machine installation and provide a unique version with my
application installation. I know we did the same for TCL to be sure
to have 8.4 version. I just wanted to know if there is some tutos about
this topic.
Regards
Karim

Hello Alan,
In fact, I want to be sure the users can run it on every machine in our
network.
Especially, I want to be able to run it on Solaris 5.8 with python 1.5
(Unix machine).
I wanted to know if I could make some custom executable like in C when
you want
to build a executable with a static library to be sure if the system
does not have
the correct shares libraries.
If you know that the machine contains `python` (whatever the version is)
you can use sys.version to check the system python's version. It can be
as simple as:
import sys
if int(sys.version[0]) > 1 or
(int(sys.version[0]) == 1 and int(sys.version[2] >= 5)):
# or you can start a subprocess instead,
# abusing import makes "if __name__ == '__main__':" magic not work
import MyMainProgram
else:
# parentheses guards for python 3
print ('script is only compatible with python version 1.5 and above')
Otherwise, if you cannot even rely on python being available, you may
need to use shell script.
Perhaps the better is to build a python version embedded in my
application installation.
Do you have any examples or tutorial on how integrate python inside a
pplication to be
sure that we have all in one and not depand on any local machine
installation environment.
I need as to embed gtk python library for graphical use.
That is indeed possible, however is there any reason why the server
don't upgrade its python version? CPython makes it easy to do parallel
installation of two different python version. If you can persuade the
machine administrator to install python2.6 as an altinstall; you can
simply change the hashbang line of your script to "#!/usr/bin/env
python2.6" and all is well.
