well you can install stuff thats not in your software manager but here is the problem :
I'm surprised
@KGIII hasn't dome an article about this yet :^)
So in the good old days you might install stuff via:
configure
make
make install
thing is it was decided that it would be nice if your system knew when software was installed and it was done in an organised way so that should there be a newer version, it was easy to update; should you want to remove it cleanly without wrecking things that could also be done . basically to keep it short none of that happens unless you use the systems software manager either via a gui or command line.
Also if its not from the right repo matching your OS release etc etc , you might compromise your system. If you are say a linux from scratch veteran, thats not a problem. If your not then its prudent to stick to your OS software system installer
The other approach is that if your OS does not have what you want, then you might consider going to an OS where you can get it.
On Arch :
Code:
