194.2.148.117: /* Installing OBS tools locally */

OBS stands for [https://build.opensuse.org/ Opensuse Build Service]. You can find out more about it from the OpenSuse webpage.

== Installing OBS tools locally ==

You'll need an [https://secure-www.novell.com/selfreg/jsp/createOpenSuseAccount.jsp?target=http://www.opensuse.org account with Novell]

You must then visit your [https://build.opensuse.org/project/list_my 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 <nowiki>http://download.opensuse.org/repositories/openSUSE:/Tools/Debian_5.0/ /</nowiki>" > /etc/apt/sources.list.d/obs.list

Then
apt-get update
apt-get install osc build qemu

OBS uses 403 redirects which hits a [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=479350 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 <nowiki>http://download.opensuse.org/repositories/openSUSE:/Tools/xUbuntu_9.04/ /</nowiki>
to a new file called:
/etc/apt/sources.list.d/obs.list

Then
apt-get update
apt-get install osc build

Now edit <code>/etc/apt/sources.list.d/obs.list</code> 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 <nowiki>http://download.opensuse.org/repositories/openSUSE:/Tools/Debian_5.0/ /</nowiki>
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:
<code>rm /etc/apt/sources.list.d/debian5_qemu.list</code>

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:

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 [https://build.opensuse.org 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 = <nowiki>https://api.opensuse.org</nowiki>

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.
<nowiki>[https://api.opensuse.org]</nowiki>
user = <username>
pass = <password>

=== Next Steps ===
