Example of use on LinuxCOE (more complex example)

When the project was mature enough to package correctly mondorescue and itself, I then decided it was time to try it on another unrelated project to see how difficult it could be and document that experience so that others could also begin to use pb for their own project.

You first have to edit your .pbrc configuration file in your home directory, which will setup things globally.

Here are my .pbrc LinuxCOE relative entries:

$ grep -E '^#|linuxcoe|default' ~/.pbrc
# Root of the temp file used to store info on the project
# Is also used to determine the root directory of the project
# No default option allowed here as they need to be all different
pbrc linuxcoe = /users/bruno/LinuxCOE/cvs/pbrc

Then you have to go under the directory you planned to store the project you want to package (/users/bruno/LinuxCOE/cvs) and you have to create there a directory pbconf which will contain everything related to project-builder around your own project. The pbrc file you indicated in the configuation file will be managed automatically by pb and you don't have to care of it. Just to reference where it will be, which will in turn give to project-builder the information of the project's directory.

$ cd /users/bruno/LinuxCOE/cvs
$ mkdir pbconf

The main configuration file under pbconf should be named with the name of the project (the one used above in the .pbrc file) with the pb extension. the one created for LinuxCOE looks like that:

$ cat linuxcoe.pb
# Project Builder configuration file
# For project LinuxCOE
# $Id$

# Global version/tag for the project
projver linuxcoe = devel
projtag linuxcoe = 1

# Adapt to your needs:
# Optional if you need to overwrite the global values above
pkgver nil
pkgtag nil

# Hash of default package/package directory
defpkgdir systemdesigner = SystemDesigner

# Hash of additional package/package directory
extpkgdir systemdesigner-docs = docs
extpkgdir systemdesigner-fedora = SystemDesigner-Fedora

# Hash of valid version names
version devel
version stable

# List of additional files on which to apply filters
# Files are mentioned relatively to pbroot
filteredfiles systemdesigner =
filteredfiles systemdesigner-docs = 

I inform pb that I will produce packages with a version-tag of devel-1, that no local package should have a different version than the project version (pkgver/pkgtag), that my default package will be systemdesigner (pb will work on it by default all the time) and that additional packages it may deal with are systemdesigner-docs and systemdesigner-fedora. In addition to standard version with numbers, pb will accpet the version devel and stable. And finally, I give to the name of all files (per package) that it will have to filter to produce the packages - more on that later on.

With that minimal configuration, you may begin to test project-builder. Try to produce a compressed tar file of your project.

$ export PBPROJ=linuxcoe
$ pb -r `pwd` cms2build

The export order will allow you to avoid precising all the time to pb that you work on the linuxcoe project. If you prefer, you can invoke pb as follows:

pb -p linuxcoe -r `pwd` cms2build

or make a shell alias, or whatever is convenient for you.

The -r option is needed at start to create the pbrc file you mentioned in your .pbrc configuration file initially. After that first invocation, you will only need to call it again, if you change the version you want to generate.

cms2build is generally the first action pb will be asked to execute as it will produce a compressed tar ball from your Confoguration Management System repository. pb is CMS agnostic, and can currently handle friendly SVN and CVS, and can be easily adapted to support others.

As a result of your commands you should see something like that:

$ pb -r `pwd` cms2build
Project linuxcoe
Action: cms2build
Packages: systemdesigner

Management of systemdesigner devel-1 (rev CVS)
Exporting /users/bruno/LinuxCOE/cvs/SystemDesigner from CVS... OK
Extracting log info from CVS... OK
Build files generated for
No Build files found for mandriva-2007.1
Creating systemdesigner tar files compressed... OK
Under /users/bruno/LinuxCOE/cvs/delivery/systemdesigner-devel.tar.gz

So it creates for you the right tar file at the right place. But it warns you that no build file was found for your project. Normal we haven't created one yet ;-) It's our next step.

You'll first need to create the infrastructure needed to host the information for building packages:

$ mkdir -p pbconf/systemdesigner/rpm
$ mkdir -p pbconf/systemdesigner/pbfilter

then thanks to the work done by Louis Bouchard to package LinuxCOE, you can take the spec file he created and adapt it to suit pb.

$ cat pbconf/systemdesigner/rpm/systemdesigner.spec
