I will provide more details about what I need to achieve

I need to create a package for a tool that I create. Actually the tool that I created is a wrapper over ovftool which is provided by VMWare. ovftool install binary is provided as a bundle hence there is no package installed in the system ( `dpkg -l` will not list ovftool package ). ovftool will be installed in /usr/bin/ location.

While creating the package I need to check if ovftool is available in the system and the version is 4.1.0. If it is not compatible, I need to fail the package installation with proper message. So how do I write setup.py for achieving the same.

you can put arbitrary python code in setup.py. so before you call setup() in the file, put something like: import subprocess try: version = subprocess.check_output(['/usr/bin/ovftool','--version']) except subprocess.CalledProcessError: print "ovftool is not properly installed" raise if not is_this_the_right_version(version): raise ValueError("ovftool is not the right version") of course, you'd probably want better error messages, etc, but hopefully you get the idea. -CHB

Thanks Salil

Hello

I was trying to create my package for distribution. I have a requirement that I need to check if one particular command is available in the system ( this command is not installed through a package - but a bundle is installed to get the command in the system ). I am using Ubuntu 14.04

Thanks in advance Salil
