Is koji the right build tool for me? and some newbie questions

[Zubin Sethna]

Hi all

 

Hope this is the correct mailing list to ask these questions.

 

I've being looking at using koji for our in house project. After
perusing the docs I have managed to set up a koji server with the web,
xml-rpc, kojira and command line client components working. So now I
want to do the client side configuration. Our software project is
distributed as RPMs (which is what made me look at koji in the first
place) and we build three site specific versions from three different
branches in CVS.

 

Reading the ServerBootstrap document on the Fedora wiki has me confused.
How do I set up koji to build a set of RPMs from CVS? Our build target
is RHEL 4 but so far I have not found any installable RPMs to run
kojibuilder on this platform. Does anyone know where I could get a
suitable RPM?

 

To build our project we need to install a set of RPMs into the build
environment that setup the libraries and header files used during the
build process. How does koji handle this? 

 

 

Thanks

Well, it doesn't require anything special, if you have a working
instance of koji. You have to add an entry in the kojibuilder config
file under "allowedSCMs", to allow the CVS checkout. and you can run a
build as "koji build <Tag-name> <CVS-SCM>"

You can also check out the chain builds feature. I have a feeling it
might be of help to you :)

Koji is a noarch pacakge. You can pick the fedora RPMs.

Koji will build a SRPM from the CVS checkout. Make sure you have the
right entries in BuildRequires and Requires in the spec file and koji
will do the rest. (Also, make sure that those RPMs are built and tagged
appropriately so that koji can make a repo which can be of use to you)

Thanks for the response Jitesh.

 

When I look to see what koji requires for install I get:

 

[zsethna@einstein koji-packages]$ rpm -q --requires -p
koji-1.2.0-3.fc7.noarch.rpm

warning: koji-1.2.0-3.fc7.noarch.rpm: V3 DSA signature: NOKEY, key ID
4f2a6fd2

/bin/bash

/usr/bin/python

config(koji) = 1.2.0-3.fc7

pyOpenSSL

python(abi) = 2.5

python-krbV >= 1.0.13

rpm-python

rpmlib(CompressedFileNames) <= 3.0.4-1

rpmlib(PayloadFilesHavePrefix) <= 4.0-1

 

 

The problem here is python 2.5 since my build machine runs on RedHat
Enterprise Linux 4 (ES) which uses an older version of python and I
can't seem to find a python 2.5 RPM that will install on this OS.

 

Also what is python(abi)? Do I have to install a full python 2.5 RPM to
satisfy this dependency?

Well, take the git head of koji and run a "make rpm" in your
environment. I am running a koji's version on python 2.4 (and it is
working fine).

You can do a --nodeps as soon as your dependency reduces to only
python(abi). It is provided on fedora's python RPMs.

You will need to rebuild koji under RHEL4 (or at least something more 
RHEL4-ish) if you want to run it on RHEL4. However....

1) There are some build deps that are missing from RHEL4, you will need 
to provide them yourself (some may be in epel, others can be rebuilt for 
RHEL4). I know it is possible to build koji for RHEL4. But...

2) Once built, there are some additional runtime dependencies for koji, 
some of them indirect (koji-builder requires a recent mock, and mock 
requires lots of things). I think you can probably get koji-hub and 
kojira to run under RHEL4 without too much pain. Getting koji-builder on 
a RHEL4 box is going to be a world of pain (mainly because of mock and 
yum) -- save yourself the time and use RHEL5 for that.

Deps you'll probably need:
createrepo
git
mock
python-cheetah
python-elementtree
python-krbV
python-sqlite
python-urlgrabber
sqlite
yum

Yes, it seems too painful to setup kojibuilder on a RHEL 4 box, mainly
due to the different version of python required and all the deps for
createrepo and mock. It is possible but as you say too much work. My
approach is to setup a 'build proxy' build host and modify my build
scripts to log into the appropriate RHEL 4 box to do the actual
compilation.
