How can one do a quick check to find if ogre is installed? For example querying the current version of ogre like OpenSceneGraph allows osgversion. A command will be preferred like this. Solution for Ubuntu will be preferred but Windows will also be good to know.
I am interested in finding all versions of ogre on my computer and remove only the versions that i don't want. What is the exact command to remove ogre? Something like:
sudo apt-get remove --purge <something>
I am not familiar with ogre but there is a simple test to see if any ogre packages are installed:
andrew@athens:~$ sudo dpkg -l *ogre*
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Architecture Description
+++-===========================-==================-==================-===========================================================
un libogre-1.8.0 <none> <none> (no description available)
un libogre-1.9.0 <none> <none> (no description available)
ii libogre-1.9.0v5:amd64 1.9.0+dfsg1-7 amd64 3D Object-Oriented Graphics Rendering Engine (libraries)
This indicates the name of the ogre package and also gives the version number that you are after. You can see that I have installed: libogre-1.9.0v5, there is a nice explanation of these codes here... but suffice it to say that that it demonstrates versions 1.8.0 and 1.9.0 not installed while 1.9.0v5 is installed.
To remove this package is then a simple process of running:
sudo apt-get remove libogre-1.9.0v5
And this will safely remove your ogre package...
