Winter 2009 SBR600 Weekly Schedule

Please note:

• The schedule here is tentative.
• Week-by-week details will be filled in as the course progresses.

Week 1 (January 12) - Introduction

Tuesday

• Welcome
• Introductions
• Intro to Build & Release
  • Brief overview of the process
    • Versioning & repository systems
    • Compilation
    • Testing
    • Packaging
    • Compositing
    • Release
    • Distribution
    • Mirroring
  • These steps vary according to the particular project/product. For example, when distributing software physically, "Release" means performing a RTM, where the final "gold disk" is sent to the duplicating house to be mass-produced; but when distributing software electronically, "Release" means sending the software to the online distribution system. The sequence of steps also varies between projects/products.
• Course Layout
  • Project-based course
  • Working with Open Source
  • Working with the Fedora Project
• Communication Tools
• Course Outline
• Visit the CDOT Area

Thursday

• Makefile Basics
  • Targets, Dependencies, and Commands
  • Implied rules (e.g., .o files)

ToDo:

Communication Lab: By Thursday, January 15, Set up your accounts (wiki, IRC, FAS2).

Lab 1: By Wednesday, January 21:

(Classes cancelled due to professor's illness)

• Complete ToDo items from week 1 if not already done.

Week 3 (January 26) - Creating RPM Packages

  • Data
    • Fonts
    • Icons
    • Sample data
  • Documentation

Creating Packages

• Packaging scenarios
• Setting up a Packaging Environment
  • Needed packages
    • rpm-build
    • rpmdevtools
    • rpmlint
  • Setting up the RPM tree
    • run rpmdev-setuptree
• Taking a look at existing source RPMS (useful as examples)
  • Installing
    • yumdownloader --source nameofpackage
    • rpm -i nameofpackage.src.rpm
    • Source will be in ~/rpmbuild/SOURCES and specfile will be in ~/rpmbuild/SPECS
  • Examine the specfile
  • Rebuild on the local machine
    • rpmbuild --rebuild nameofpackage.src.rpm
  • Building from the spec file
    • cd ~/rpmbuild/SPECS; rpmbuild -ba nameofpackage.spec

Writing a specfile

• Run rpmdev-newspec packagename in ~/rpmbuild/SPECS
• Edit the skeleton specfile.
• Test it: rpmbuild -ba packagename.spec

Layout of a specfile

• Basic Sections

1. preamble - basic metadata
2.  %prep - commands to prepare the package for building
3.  %build - commands to build the package
4.  %install - commands to install the built files
5.  %check - commands to check/test the built files (optional, often not included)
6.  %clean - commands to clean up the disk space
7.  %files - list of files to be included in the pacakge
8.  %changelog - record of the package's change-history

• Scriptlets
  •  %pre
  •  %post
  •  %preun
  •  %postun
• Macros
  •  %{_tmppath}
  •  %{buildroot}
  •  %{_bindir}
  •  %{_datadir}
  •  %{_mandir}
  •  %{_smp_flags}
  •  %setup
  •  %configure
  •  %makeinstall

Creating a Simple Package

• NLED
• Writing the specfile
• Testing the specfile
• Using rpmlint

Resources

• Fedora Package Maintainers page
  • Packaging How-To
