  • 1. RPM Building © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> All Rights Reserved.
  • 2. What to Expect? System Setup to build an RPM Steps to build an RPM Testing the built RPM © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 2 All Rights Reserved.
  • 3. Master Steps Setting up the build system Collating the package source Writing the .spec file Actually building the rpm Testing the built rpm © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 3 All Rights Reserved.
  • 4. System Setup Creating a separate login, say rpmbuild To avoid security hazards Create a package directory mkdir <pkg_dir> Create the following subdirectories BUILD: Place for building by rpmbuild RPMS with i386, i686, noarch: For built binary package SOURCES: For the original software sources SPECS: For .spec file SRPMS: For built source rpm tmp: For temporary files (Optional) Install the following commands rpmbuild: Typically part of rpm-build package Other Optionals: rpmlint, gpg © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 4 All Rights Reserved.
  • 5. Steps to Build an RPM Collating the package sources Typically as a .tgz file Writing a spec file Basic structure Building the package Cleaning the package Installing the package Uninstalling the package Building using rpmbuild © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 5 All Rights Reserved.
  • 6. Locate your Templates Create the .tgz of sources View the 'sources' target in the makefile Output: SOURCES/pkg_cmd-1.0.tgz Spec file & the macros Example: SPECS/pkg_cmd-1.0.spec Building the rpm View the 'build' target in the makefile Output: RPMS/pkg_cmd-1.0-1.i386.rpm © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 6 All Rights Reserved.
  • 7. Spec Sections Introduction Defines, Keywords, %description %prep – Unpack source code %build – Compile code % install – Install code onto build machine %clean – Clean up code %files – List of files to use %changelog – Change log of the code © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 7 All Rights Reserved.
  • 8. %file specific Macros %defattr – Default attributes file attributes, owner, group, dir attributes %doc – Documentation files %exclude – Exclude these files Useful Path Macros %{_prefix} %{_bindir}, %{_sbindir}, %{_libdir} %{_datadir}, %{_sysconfdir} %{_mandir}, %{_infodir} %{_gamesbindir}, %{_gamesdatadir} © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 8 All Rights Reserved.
  • 9. Additional Spec Sections %pre – Execute before install %post – Execute after install %preun – Execute before uninstall %postun – Execute after uninstall Option to these: -p <interpreter> © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 9 All Rights Reserved.
  • 10. Signing an RPM Assuming that a GPG key is there Add the following macros in the .spec file %_signature gpg %_gpg_path /path/to/.gnupg %_gpg_name name lastname (comment) <email> 'gpg --list-keys' to get the value %_gpgbin /usr/bin/gpg Build with --sign option to rpmbuild Alternatively, an RPM can be signed as follows rpm --addsign <rpm_package> After putting the above macros in ~/.rpmmacros © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 10 All Rights Reserved.
  • 11. Interesting Spec Macros Triggers on operation with other packages %triggerin <pkg> – On installing <pkg> %triggerun <pkg> – On uninstalling <pkg> %triggerin <pkg> – After uninstalling <pkg> Details about all /usr/lib/rpm/macros Place for repeated macros ~/.rpmmacros © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 11 All Rights Reserved.
  • 12. Building the RPM Using rpmbuild rpmbuild <build_options> [options] <spec_file> <build_options> -bs, bb, -ba -bp (%prep), -bc (%build), -bi (%install) -bl (list check from %files) A very clean way rpmbuild -ba --rmspec --rmsource rpmbuild --rebuild © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 12 All Rights Reserved.
  • 13. Testing the RPM Build(ing) Are rpms created in their directories? Are the rpms with the correct names? Is the rpm info correct? Issued by rpm -qlivp --changelog <rpm_package> Linting the rpms or even the spec files rpmlint [-i] <rpm_package | spec_file> Install Tests Expected files at expected places & privileges Binaries executable, Documentation accessible Various installs, uninstalls On different machines Without required packages © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 13 All Rights Reserved.
  • 14. Backup © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 14 All Rights Reserved.
  • 15. Options to setup -c – Create upper directory first Useful for archive without a parent directory -D – Does not delete the directory Useful in later setups, if multiple -T – Override the default behaviour Rather specified by -a 0, -b 0, etc -n <name> - <name> what source unpacks to Useful if different from the source name © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 15 All Rights Reserved.
  • 16. Generating a GPG key Generate a key using gpg --gen-key Listings (provides <UID>) gpg --list-sigs gpg --list-keys Generating a public key gpg --armor --export "<UID>" > my.key.file.asc Publishing the public key gpg --keyserver pgp.mit.edu --send-key "<UID>" © 2010 Anil Kumar Pugalia <email@sarika-pugs.com> 16 All Rights Reserved.
