Mer/Build/Install OBS
OBS stands for Opensuse Build Service. You can find out more about it from the OpenSuse webpage.

Installing OBS tools locally
You'll need an account with Novell
You must then visit your project list and click : "Let me build my packages!"
Debian
Assuming a Debian Testing development box locally:
To get the OBS tools repository add an entry to the sources.lists:
echo "deb http://download.opensuse.org/repositories/openSUSE:/Tools/Debian_5.0/ /" > /etc/apt/sources.list.d/obs.list
Then
apt-get update apt-get install osc build qemu
OBS uses 403 redirects which hits a bug in apt in Lenny.
You can workaround using:
wget http://download.opensuse.org/repositories/openSUSE:/Tools/Debian_5.0/./all/build_2009.09.23-1_all.deb apt-get -f install
Ubuntu
Assuming an Ubuntu9.04 development box locally:
To get the OBS tools repository add the following line:
deb http://download.opensuse.org/repositories/openSUSE:/Tools/xUbuntu_9.04/ /
to a new file called:
/etc/apt/sources.list.d/obs.list
Then
apt-get update apt-get install osc build
Now edit /etc/apt/sources.list.d/obs.list and comment that line out.
Note there is a problem in Ubuntu9.04 osc as of 25 May '09... to fix it, do this as root:
cd /usr/lib/python2.6/dist-packages/ ln -s ../site-packages/osc* .
Suse don't have an Ubuntu qemu yet so we use the one they make for Debian (bug raised):
Add the following lines:
deb http://download.opensuse.org/repositories/openSUSE:/Tools/Debian_5.0/ /
to a new file called:
/etc/apt/sources.list.d/debian5_qemu.list
Then
apt-get update apt-get install qemu
now remove that file:
rm /etc/apt/sources.list.d/debian5_qemu.list
and run
apt-get update
Troubleshooting
If you get the following error when adding one of these repos
W: GPG error: http://ftp.debian.org stable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY SOMEKEY
Then run the command
gpg --keyserver pgpkeys.mit.edu --recv-key SOMEKEY && gpg -a --export SOMEKEY | sudo apt-key add -
replacing SOMEKEY with the complained about key
RedHat Enterprise Linux 5
Assuming a RHEL 5 box locally:
The M2Crypto package that comes w/ RHEL5 is too old. I retrieved the 0.19.1 source rpm from Fedora 10 and built it for my architecture. But you will need to update this package to at least version 0.19 before installing the OBS packages.
Install the public key for the OBS RPM repository:
rpm --import http://download.opensuse.org/repositories/openSUSE:/Tools/RHEL_5/repodata/repomd.xml.key
To get the OBS tools repository recognized by yum:
echo "[obs]" > /etc/yum.repos.d/obs.repo echo "name=OpenSUSE Build System" >> /etc/yum.repos.d/obs.repo echo "baseurl=http://download.opensuse.org/repositories/openSUSE:/Tools/RHEL_5" >> /etc/yum.repos.d/obs.repo
Then:
yum makecache yum install osc build qemu-svn
This technique is likely to work with RHEL derivatives like CentOS.
Other distributions
You can find openSuse build tools for various distributions at http://download.opensuse.org/repositories/openSUSE:/Tools/
All OSes
NAME=<username> cat <<EOF >> /etc/sudoers $NAME ALL=NOPASSWD: /usr/bin/build $NAME ALL=NOPASSWD: /usr/sbin/chroot EOF
Now, as a normal user, run
osc
and enter novell.com username/passwd when prompted (note these are stored in cleartext in the config file). Note this isn't supposed to do anything (it prints out the osc help) but it stores your name/pw for future use.
Go and login.
Make sure you click the "let me build packages" button.
There is a link to 'Home Project' on the left, follow this and enter a description.
Note that if, in the future, qemu fails to work you may need to setup the associations for arm binaries by running:
qemu-binfmt-conf.sh
Handle OBS using ':' in filenames
To help bash completion etc:
export COMP_WORDBREAKS="
> "\""'><=;|&("
or
COMP_WORDBREAKS=${COMP_WORDBREAKS//:/}
Local osc setup
Create a local build path.
mkdir -p ~/maemo/Mer/obs
All references below with (yourusername) should of course be replaced with the login name on your local machine.
You can now check some settings in your ~/.oscrc :
This is the OBS builder we're using... maybe we'll use a maemo.org instance one day?
apiurl = https://api.opensuse.org
This specifies where all the cached binary packages are held to create a chroot build environment. Around 300MB.
packagecachedir = /home/(yourusername)/maemo/Mer/obs/.pkg-cache/
This specifies the default location where a complete chroot build will be installed. This will be a minimal OS install - allow 400MB minimum. Replace (yourusername) with your current login name
build-root = /home/(yourusername)/maemo/Mer/obs/build-%(repo)s-%(arch)s
The next section is credentials for access control to the builder.
[https://api.opensuse.org] user = <username> pass = <password>
Next Steps
Go back up to Mer/Build and then onto Application Building
