The following steps explain how to install a development environment onto your core in a chroot environment, so that your running core and its database are not affected. Alternatively, you could build on a separate machine or virtual machine with a clean Kubuntu install. There are notes to this effect at the end of the page.
Setting up a chroot environment
Start with becoming root on your core (or standalone builder). The following steps will need to be done using super user privileges.
sudo su -
Create the environment
Note: these steps must be performed only once, if you are creating a chroot environment to build in (recommended)
apt-get install debootstrap debootstrap --arch i386 precise /opt/builder-ubuntu-precise-i386/
Mount required directories
Note: these steps must be performed after each reboot (or put in /etc/fstab of the root machine), if you are using a chroot environment
mount --bind /dev /opt/builder-ubuntu-precise-i386/dev mount none /opt/builder-ubuntu-precise-i386/proc -t proc mount none /opt/builder-ubuntu-precise-i386/dev/pts -t devpts
Change-root into the environment
Note: these steps must be performed after each reboot to access to build environment (if in a chroot)
Verify apt's list of repositories
Make sure /etc/apt/sources.list (inside the chroot) contains something very similar to:
deb http://archive.ubuntu.com/ubuntu/ precise main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ precise main restricted universe deb http://archive.ubuntu.com/ubuntu/ precise-updates main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ precise-updates main restricted universe deb http://security.ubuntu.com/ubuntu precise-security main restricted universe deb-src http://security.ubuntu.com/ubuntu precise-security main restricted universe deb http://www.e-tobi.net/vdr-experimental/ sid base deb http://deb.linuxmce.org/ubuntu/ precise main
Add the e-tobi.net GPG key
gpg --keyserver pgp.mit.edu --recv-keys F7180D26AEDAA642 gpg --export --armor F7180D26AEDAA642 | sudo apt-key add -
Installing needed packages
Important! Perform these also after chrooting if you are building in a chrooted environment.
If you get messages like /usr/bin/locale: Cannot set LC_MESSAGES to default locale: No such file or directory, that meens that $LANG is set. Either clear the LANG or install the needed language pack (english given example given in the code-snip below).
(Leave the root password for MySQL empty.)
apt-get update # Uncomment either of lines below if needed (see explanation above) #unset LANG #apt-get install language-pack-en-base apt-get dist-upgrade apt-get install aptitude openssh-client mysql-server
If you are installing on a chrooted environment and get an error similar to the following:
invoke-rc.d: initscript mysql, action "start" failed. dpkg: error processing mysql-server-5.5 (--configure): subprocess installed post-installation script returned error exit status 1 No apport report written because MaxReports is reached already
It may because the installer tries to start MySQL and is unable to due to networking so try running the step below (Reconfigure to not open TCP-IP network port) and then running
apt-get install mysql-server
Reconfigure MySQL to not open a TCP-IP network port
(only needed if you are building in a chrooted environment)
sed 's/^[^#]*bind-address[[:space:]]*=.*$/#&\nskip-networking/' -i /etc/mysql/my.cnf
Start MySQL Server
Do not execute the mysql start before doing the sed statement listed above.
Building from source
For a more in detail description of all the steps involved see Building LinuxMCE 0804
Currently the focus is on getting the following to work completely.
You should only have to do this part once initially.
Obtaining the build scripts
apt-get install subversion svn co http://svn.linuxmce.org/svn/trunk/src/Ubuntu_Helpers_NoHardcode
Installing the build scripts
cd Ubuntu_Helpers_NoHardcode ./install.sh
Configuring the build scripts
cat >/etc/lmce-build/builder.custom.conf <<EOF # Avoid DVD build step[s] do_not_build_sl_dvd="yes" do_not_build_dl_dvd="yes" # Create fake win32 binaries win32_create_fake="yes" # Point to the development sqlCVS server for 0810 sqlcvs_host="schema.linuxmce.org" EOF
Preparing for build
The preparation steps one at a time (recommended):
prepare-scripts/install-build-pkgs.sh #prepare-scripts/cd1-prepare.sh #prepare-scripts/cd2-prepare.sh prepare-scripts/create-diskless-debootstrap.sh prepare-scripts/import-external-files.sh prepare-scripts/preseed-build-pkgs.sh
Or, you could do them all in one go with:
Building from source
All the build steps can be executed seperately (recommended at least the first time):
build-scripts/checkout-svn.sh build-scripts/import-win32bins.sh build-scripts/build-replacements.sh build-scripts/build-makerelease.sh build-scripts/import-databases.sh build-scripts/build-maindebs.sh build-scripts/get-closed-source-debs.sh build-scripts/create-repo.sh #build-scripts/cd1-build.sh #build-scripts/cd2-build.sh
Or the following script will run them all:
Using the build's output
The build.sh script puts all created deb-files under /var/www. Setup a web server to point to that directory.
sudo apt-get install apache2
In the machine, where you want to test the build, follow the instructions on using the alpha build. After the step pre-install-from-repo.sh, go into /etc/apt/sources.list, and replace the deb.linuxmce.org line with
deb <ip-address-of-your-builder> ./
and re-run apt-get update
If you want to speed up building on a multi-core machine, create (or append) /etc/lmce-build/builder.custom.conf and add a line such as:
to build using 4 threads. Adjust for you cpu core # +1 for optimal build efficiency.
Without -j 2
23:36:44 Compiling and building packages 01:42:50 *** STEP: Download closed source debs
Total: roughly 2h 6minutes for compiling
With -j 2
13:13:44 Compiling and building packages 14:51:56 *** STEP: Download closed source debs
Total: roughly 1h 38minutes for compiling
Notes for installing on a virgin Kubuntu 1204 installation (no chroot)
- There is no need to run the command below, IF you are not chroot'ing, but it also doesn't hurt unless you expect to access the db from an external system.
sed 's/^[^#]*bind-addressspace:*=.*$/#&\nskip-networking/' -i /etc/mysql/my.cnf
- After you reboot, you will notice that KDE mysteriously vanished, and you will go to a gnome desktop. I'm not sure why this is, but it does not seem to affect the builder any. -- is this still the case??? <phenigma>
- If you want to run this builder headless (or just want to ability to ssh in to it), then you must configure it for ssh access by installing an ssh server
sudo apt-get install openssh-server
