Question about building RPMs
 

Say i already have compiled the source and i want to make an rpm. What do i do with it? Can i utilize the make file?

http://www.rpm.org/max-rpm/index.html provides good information on creating RPMs. The short answer is, yes, you can use the make file. You'll need to create a spec file for your RPM, that tells rpmbuild which make targets to execute to build, test, install, clean, etc.
