Editor's Note: The preferred method for building RPM's is from source. These instructions are for situations where this is not possible or practical.
The trick to building rpms from binaries directly:
- Create a spec file for your rpm, but leave the %prep, %setup, %build, and %install sections blank. Put the spec in /usr/src/redhat/SPECS.
- In the %files section of your specfile, list all the binary files you'd like included in the RPM, with full path information.
- Create an empty tarfile for your project... If you've set your Source: field in the spec file to be something like "project.tgz", make sure that your "empty" tar file contains only a "project" directory. Place this tarfile in /usr/src/redhat/SOURCES.
- cd /usr/src/redhat/SPECS and issue the command "rpm -bb specfile.spec"
RPM should now go and build the RPM directly from binaries.
Note: I got caught on the %files section in the specfile - I kept seeing the error "filename xyz listed twice". The problem was that my list of files was created from the output of the find command and looked something like this:
RPM was seeing the directory1 and directory2 as files, and considered the entries following them to be duplicates. I should have used the ``find -type f'' option to specify files only.
