Hi there,
maybe for many of you this is an easy task, but I still don't know
a way of disinstalling programs installed by src (that is not using
deb packages, as I'm on Ubuntu). Of course they don't appear
in synaptic and, even looking around the web, I didn't find any
working solution.
I recommend using 'stow' when you install.
Compile with prefix=/opt/name-and-version (say /opt/ardour-3.0.1) and
after installing run 'stow -d /opt -t /usr/local ardour-3.0.1' to
create symlinks in /usr/local.
If you later decide the program is buggy as hell and want to remove it
you run 'stow -D -d /opt -t /usr/local ardour-3.0.1 ; rm -rf
/opt/ardour-3.0.1' to remove the symlinks and the program.
