I recently had a need to rebuild a x86_64 rpm from the source rpm on RHEL 6. I needed the Darwin Streaming Server from Apple, but it seems to be neglected. So no rpm at all.
A prerequisite for this is a key to sign the rpm with. If you don’t have one, creating one won’t be covered here.
Download the source rpm into an appropriately rpm src directory and then extract the .spec file with
rpm -Uvh DarwinStreamingServer-6.0.3-2.src.rpm
Here you can edit it if needed. Then to build:
rpmbuild -ba –sign –target x86_64 SPECS/DarwinStreamingServer.spec
This would also build, bypassing the need to extract the spec file, if you don’t need to edit the spec file.
rpmbuild -v –sign –rebuild DarwinStreamingServer-6.0.3-2.src.rpm
I was able to verify the key was used:
rpm -i DarwinStreamingServer-6.0.3-2.src.rpmrpm –checksig RPMS/x86_64/DarwinStreamingServer-6.0.3-2.x86_64.rpm
and compare the output of:
gpg –list-keys
Be sure to read the man page of rpmbuild for the meanings of the -ba, -bb, etc switches.
