Guess I just had to know. 🙂
Initial VPS setup
– Add normal user account
– adduser <username>
– Generate ssh keys
– Add other ssh keys to ~/.ssh/authorized_keys
– change permissions chmod go-rw authorized_keys
– Disable root login
– PermitRootLogin no
– Add the bzr ppa to /etc/apt/sources.list
– deb http://ppa.launchpad.net/bzr/ubuntu hardy main
– deb-src http://ppa.launchpad.net/bzr/ubuntu hardy main
– In order to install the latest and greatest bzr 1.9 at the time of writing the updates repo needs to be added also.
– deb http://archive.ubuntu.com/ubuntu hardy-updates main
– Install bzr
– mkdir vc
– cd vc
– bzr init-repo bzr
– To give bzr a little more room to breath create another swapfile and activate it
– dd if=/dev/zero of=/swapfile bs=1024 count=196608
– mkswap /swapfile
– swapon /swapfile
– Add the following to the fstab file so that the swapfile will be available after a reboot
– /swapfile none swap sw 0 0
– Fix the locale problem (i386)
– apt-get install language-pack-en
– Edit the sudoers file by adding the following line
– <username> ALL=(ALL) ALL
unpack it to your working directory
Before trying to build the lsm toolbox you need to check that you have access to the gcc4 compiler from within your working environment, you can check this by:
Which should return something similar to this
Using built-in specs.
Configured with: ../configure –prefix=/usr –mandir=/usr/share/man –infodir=/usr/share/info –enable-shared –enable-threads=posix –enable-checking=release –with-system-zlib –enable-__cxa_atexit –disable-libunwind-exceptions –with-gxx-include-dir=/usr/include/c++/3.4.3 –enable-libgcj-multifile –enable-languages=c,c++,java,f95 –enable-java-awt=gtk –disable-dssi –with-java-home=/usr/lib/jvm/java-1.4.2-gcj-188.8.131.52/jre –with-cpu=generic –host=x86_64-redhat-linux
Thread model: posix
gcc version 4.1.2 20070626 (Red Hat 4.1.2-14)
Should you not have the gcc4 complier installed you need to install the package gcc4-4.1.2-14.EL4 and usually create a sim link in your ~/bin folder to ensure that the version 4 compiler will be picked up first.
ln -s /usr/bin/gcc4 gcc
Now that the build environment is sorted out its onto the actual process of building the lsm toolbox. So, edit the Makefile in lsm/csim/src change the default build rule to
default: version.i filepermissions csim.mexga64 install.m
The default build rule should be around line 135 in the Makefile. Depending on where matlab is installed the file paths which are hardcoded in the build file may need to be changed. In this example using the vim regular_expression to change the path from /usr/local/matlab to /opt/matlab/ins
Now move to the csim directory and run the make command as normal.
Should an error similiar to the quote below occur,
Invalid MEX-file ‘/home/<username>/<working directory>/lsm/csim/csim.mexa64′: /opt/matlab_sp3_64/ins/bin/glnxa64/../../sys/os/glnxa64/libgcc_s.so.1: version `GCC_4.2.0’ not found (required by /usr/lib64/libstdc++.so.6).
The solution to seems to be to move the libgcc_s.so.1 file out of the way so that matlab will use the system one first. The file can be moved via the normal unix command ‘mv’ as shown below.
mv libgcc_s.so.1 libgcc_s.so.1.orig

In order to use the bzr distributed version control system on Redhat Enterprise Linux 4 (RHEL) you first have to build python 2.4+ (and some additional modules) as RHEL shipped with 2.3.* of python which isn’t supported by bzr. In this article I will be building python 2.4.5 and the addional modules required for bzr 1.6.1 into a folder in my home directory so as not upset any of the applications that rely on the RHEL supported version of python. So lets get started;
First get python 2.4.5 using wget as the downloader
patrickd tmp $ wget -c http://www.python.org/ftp/python/2.4.5/Python-2.4.5.tar.bz2
Now lets use tar to decompress it.
patrickd tmp $ tar xfjv Python-2.4.5.tar.bz2
[ ……………. ]
Enter the directory that tar just decompressed it to and configure it, so that it will be installed into the directory ‘/home/patrickd/apps/python’
patrickd Python-2.4.5 $ cd Python-2.4.5
patrickd Python-2.4.5 $ ./configure –prefix=/home/patrickd/apps/python
checking MACHDEP… linux2
checking for –without-gcc… no
[ ……… ]
Once, python is configured. It is time to build it using the ‘make’ command, then create the directory that we intend to install python to and then finally install python into the preconfigured directory.
patrickd Python-2.4.5 $ mkdir -p /home/patrickd/apps/python
patrickd Python-2.4.5 $ make
[ …… ]
patrickd Python-2.4.5 $ make install
[ …… ]
After python has been installed, it now time to setup some environment variables. That will enable the new 2.4 version of python to be used as the default python rather than the redhat compilied version of python.
patrickd Python-2.4.5 $ export PATH=$HOME/apps/python/bin:$PATH
patrickd Python-2.4.5 $ export PYTHONPATH=/home/patrickd/apps/python/lib/python;
Check to make sure that the environment variables are correctly set by calling python and checking the version number.
patrickd Python-2.4.5 $ python -V
Now we need to get some additional python modules that are used by bzr.
patrickd tmp $ wget http://www.cosc.canterbury.ac.nz/greg.ewing/python/Pyrex/Pyrex-0.9.8.5.tar.gz
patrickd tmp $ wget http://effbot.org/media/downloads/cElementTree-1.0.5-20051216.tar.gz
patrickd tmp $ wget http://www.lag.net/paramiko/download/paramiko-1.7.4.tar.gz
As before decompress them,
patrickd tmp $ tar xfzv Pyrex-0.9.8.5.tar.gz
patrickd tmp $ tar xfzv cElementTree-1.0.5-20051216.tar.gz
patrickd tmp $ tar xfzv paramiko-1.7.4.tar.gz
Now build and install each of them in turn.
patrickd tmp $ cd Pyrex-0.9.8.5/
patrickd Pyrex-0.9.8.5 $ python setup.py install
patrickd Pyrex-0.9.8.5 $ cd ..
patrickd tmp $ cd cElementTree-1.0.5-20051216/
patrickd cElementTree-1.0.5-20051216 $ python setup.py install
[ ………… ]
patrickd cElementTree-1.0.5-20051216 $ cd ..
patrickd tmp $ cd paramiko-1.7.4/
patrickd paramiko-1.7.4 $ python setup.py install
[ ……… ]
patrickd paramiko-1.7.4 $ cd ..
Finally its time to get the bzr source code and install it into the new 2.4.5 python installation.
patrickd tmp $ wget https://launchpadlibrarian.net/17315400/bzr-1.6.1.tar.gz
patrickd tmp $ tar xfzv bzr-1.6.1.tar.gz
patrickd tmp $ cd bzr-1.6.1
patrickd bzr-1.6.1 $ python setup.py install –home /home/patrickd/apps/python/
patrickd bzr-1.6.1 $ cd ~
After building and installing bzr its now time to check that bzr is correctly installed.
patrickd ~ $ bzr version
Bazaar (bzr) 1.6.1
Python interpreter: /home/patrickd/apps/python/bin/python 2.4.5
Python standard library: /home/patrickd/apps/python/lib/python2.4

I’ve been running 8.04 beta for a while now, with kernel 2.6.22-14 the system boots and runs just fine. However, with the recent updates to the kernel 2.6.24-15 and then to 2.6.24-16 the system fails to boot and “hangs” at the “loading” screen with the blue progress bar just moving back and forward. In the trimmed menu.lst only the last option boots.
patrickd@ubuntu:/media$ lsb_release -rd

After some back and forth with the ubuntu developers it using this bug report on launchpad, It appeared that the newer versions of the kernel where unable to mount my root partition. Then after some digging about in one of my old note books I discovered that I’d come across the same problem with another distro and at the time the solution was to add “pci=nomsi” to the kernel boot options and thankfully that seemed to have solved the problem this time to.
This workaround enabled my system to boot with the ubuntu 2.4.26-16-generic kernel.
patrickd@ubuntu:~$ uname -a
Linux ubuntu 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux
The workaround for me was to add “pci=nomsi” to the kernel boot options, so the entry in fstab now looks like;
kernel /boot/vmlinuz-2.6.24-16-generic root=UUID=761e8f2c-dd8d-4042-a5bb-2ead0c26c54e ro quiet pci=nomsi splash
After installing pingus on ubuntu hardy (8.04) I discovered that the sound only worked when no other applications where using the sound card, which is a bit of a pain. When trying to start pingus from a gnome terminal the following message appeared;
Welcome to Pingus 0.7.2!
data path: /usr/games/../share/games/pingus/data/
language: English (en)
font encoding: iso-8859-1
sound support: enabled
music support: enabled
Unable to initialize SDL_Mixer: No available audio device
Pingus: Unknown throw caught!
The interesting thing about this error is that it doesn’t appear to be pingus specific instead a generic SDL type problem. So, once again after some googling the solution that I came up with is shown below, I had tried a couple of other ones like “$ padsp pingus”, padsp appears to be a wrapper for pulseaudio (which is the default backend for hardy) and “export SDL_AUDIODRIVER=esd et” but this didn’t work either. I even found a post which suggested using “export SDL_AUDIODRIVER=pulse” but again this didn’t work for me. In the end I installed the pulseaudio “driver” for libsdl kind of obvious when you think about it 🙂 ;
