Well, this approach, as installing in /opt (or whatever directory
without the package manager to know), is really error prone on the mid
term, I think. For on or two programs, this works ok. But still, you
have no ways to remove software this way, most of the time, because
you have no information on what files and modifications to the system
was done by the software you've installed (except if an uninstall
target was done in the source of the programs). And then comes the problem of libraries. In that case,
it quickly
become a big mess if you do not know exactly what you are doing. Let's
say for example you installed a library from source, and then it
become available for your package manager: you still may use the
version installed from source, wihtout you knowing it, and it may
cause some random crash because of some version differences.
Basically, installing from sources without the help of the package
manager is ok if nothing depends on what you are installing. It
quickly become unmanageable if other softwares depend on it. I found
checkinstall much more robust.
yeah, but installing into /opt/package-version works on pretty much
all unix(like) OSs regardless of what package system you use. You're
right that it's not a good general solution but it's pretty handy for
small-scale installations (few programs and/or libs). Plus since
everything goes into one directory you're pretty sure that the rest of
the system is not affected (not sure how good is checkinstall in this
area, it tries to check what the install did but I'd rather have install
NOT touch the rest of the system, whether under supervision or not).
