Uninstall the EMC2

Uninstall the EMC2 seems to be a headache, but i still want to do so. in the wiki, it follows this steps:

Uninstalling EMC2 from source
If you wish to remove a package, a simple `sudo apt-get remove emc2` will suffice. However, if you've installed emc2 from source with `make install` then there will be files left around everywhere. You can not then install emc2 from a package, as the files will conflict. This is an attempt to document all of them. The following script assumes that you still have the compiled emc2 source tree.

export SRCPATH=<path to your emc build>

#remove the python modules
cd /usr/lib/python2.4/site-packages/
ls $SRCPATH/lib/python | xargs sudo rm -r

sudo rm -r /usr/local/etc/emc2/ /usr/realtime*/modules/emc2/ /usr/local/share/emc/ /usr/local/share/axis/
sudo rm /etc/init.d/realtime

cd /usr/local/bin/
ls $SRCPATH/bin/ | xargs sudo rm
sudo rm emc emcmkdesktop halrun

cd /usr/local/lib
ls $SRCPATH/lib/ | xargs sudo rm

um, i guess that's everything. You may need to apt-get remove --purge emc2 if you installed it "over" the existing install, otherwise you will get the wrong /etc/init.d/realtime script (or no script!)

One way to avoid this predicament is instead of "make install", to use the "checkinstall" program, which monitors the install process and creates a package for you that can easily be uninstalled.



but i want to know: i install the EMC2 with the LIVECD, so i do not know if i should follow the way of uninstall the package, or the way of uninstall the source???

yep, i think i have solved this problem. Installing the EMC2 with the liveCD means nothing but a EMC2 package. So when I want to remove this package, just "remove EMC2" makes it done~~and when I want to get this back, just "install EMC2". But I do not know if I could make a patch file to this EMC2?? Something like "patch ./###*****" to patch a file into EMC2??? anybody knows?
