I am using FC 5 and still have much to learn about Linux. One issue that confuses me relates to the "proper" locations of application files. As a specific example, I am using the latest Eclipse package, Ver 3.1.2. However, I am also experimenting with Eclipse on a Windows machine, and its version is 3.2. So for comparison purposes, I downloaded Eclipse Ver 3.2 to my home directory on my Linux machine. Thus, I now have two versions of Eclipse on my Linux machine. (Both seem to work correctly with the corresponding CDT plugins.) Nevertheless, this raises lots of questions in my mind: Is this a sane thing to do? Should I try to relocate the files into more appropriate directories? Will this mess up yum? Please note that I am not too concerned with this specific example. The problem arises every time I build new applications from the original source files. I am not sure what to do with the created files. Are there standard procedures to follow? How will this affect yum-related installations? Thanks, Bob
