I'm trying to understand the rational behind installing from software from source in Ubuntu 12.04.
Obviously, I know I can download what I need from repos, but I want to develop a deeper understanding of Linux, hence the question.
I've search all over the place but I can't quite get my head around it. Here's why;
As a windows users, when I download a program I double click it, and it installs into the "program files" directory unless I specify otherwise. When I want to uninstall it, Windows has a tools that does that for me.
When I install a program in Linux, where does it install to? How do I uninstall it afterwards? Are there residual files left over? How would I tell if it's been fully removed?
For instance, I'm going to install LMMS (Linux Multimedia Studio) from source. I download and decompress the tar ball, and have a folder name lmms_XXX.tar (whatever).
The folder is now on my desktop with an install file. If I run the install file from that location, does it install into that folder? If so, can I move that folder to where ever i want? I want thinking about putting it in /opt/lmms
Thank in advance for your help.
