I'm attempting to make some RPM packages, but I'm not sure how to go about writing the %file list.

The programs that I'm trying to install have makefiles, so I'll be using .configure/make/make install, but I don't know how to determine what all files need to be associated with the RPM. I've googled, but I can't seem to find a solution, anywhere.

Any help would be greatly appreciated!

Ok, I'm trying to package rpm files myself with mixed success (I have packaged a few and I'm still cursing on others ...), so I can't say for sure that I'm doing the right thing here but generally I leave the %files section empty and only put someting in there when I get an error message complaining about installed but unpackaged files, I then include these files under the %file section.

Does that mean that all installed files are then put on the list? Else it would render the RPM un-uninstallable.

As I understand it the %files section lists all the files that need ot be packaged for the rpm to install.
When you run rpmbuild -ba package.spec it generates a directory /var/tmp/package_name-buildroot

If you cd to /var/tmp/package_name-buildroot and do
$ find
it will produce a list.
Make sure that the files listed are present in your %files section.

But as I said I proceed by elimination (until I learn about a better way) so I leave the %files section blank and when at the end of the process I get the list of "installed but unpackaged files" I copy that list in the %files section and it works all the time.

There's probably a much "cleaner" or "more correct" way of doing this but I don't know about it yet.
I packaged a bunch of files and they install without any problem on various systems.
