A quick howto on RPM rebuilding from source:
yum groupinstall "Development Tools" yum install rpmdevtools # unpack old tar.gz
tar zxvf my-package-0.0.0.tar.gz mv my-package-0.0.0.tar.gz orig.my-package-0.0.0.tar.gz
[change interested files]
# create a new tar.gz file, preserving privileges
tar -pzcvf my-package-0.0.0.tar.gz my-package-0.0.0/
Create RPM from tar.gz
rpmbuild -tb my-package-0.0.0.tar.gz
The “-p” stays for “preserve privileges”
You got something like:
Wrote: /usr/src/redhat/RPMS/i386/my-package-0.0.0.i386.rpm cd ~ cp /usr/src/redhat/RPMS/i386/my-package-0.0.0.i386.rpm ./ rpm -i my-package-0.0.0.i386.rpm
