<p>Insert your Ubuntu 9.10 Live CD</p>
<p>Click &#8220;Try Ubuntu without any changes to your computer&#8221;</p>
<p>Once loaded click Applications &gt; Accessories &gt; Terminal</p>
<p><code>sudo fdisk -l</code> That&#8217;s an L (not caps)</p>
<p><img class="aligncenter size-large wp-image-606" title="Screenshot-alex@Icarus-Desktop: ~" src="http://www.alexsleat.com/wp-content/uploads/2010/03/Screenshot-alex@Icarus-Desktop--560x371.png" alt="" width="560" height="371" /></p>
<p>This displays all partitions on your system, in my case the installation of my Ubuntu system was /dev/sda5 so replace this for yours in the rest of the code.</p>
<p><code> sudo mount /dev/sda5 /mnt<br />
sudo grub-install --root-directory=/mnt/ /dev/sda</code></p>
<p>If all goes successfully you should be done, try rebooting and see if your Ubuntu shows up.</p>

&#8220;When faced with two choices, simply toss a coin.
It works not because it settles the question for you,

			<content:encoded><![CDATA[<p>While installing opencv on an older version of debian for work I kept getting an error while loading shared libraries which turned out to be a pretty easy fix, just finding the libraries and adding them to the dynamic linker.</p>
<p>The libraries I was having trouble with below:<br />
<code>./blobtrack: error while loading shared libraries: libcxcore.so.1: cannot open shared object file: No such file or directory</code></p>
<p><code>ffmpeg<br />
ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory</code></p>
<p>I used the &#8216;locate&#8217; command to find where the libraries were eg:<br />
<code>locate libcxcore.so.1</code><br />
This outputted a few locations of where the library was, I decided to use the /usr/local/lib version as both libraries I needed were in there and did the following command to add them to ld.so.conf and reload the dynamic linker:<br />
<code>sh -c 'echo "/usr/local/lib" >> /etc/ld.so.conf &#038;&#038; ldconfig'</code></p>

<p>I know I&#8217;m a bit late in posting this but before playing this Uncharted 2 would have been top spot maybe followed by Batman: Arkham Asylum but after grabbing a copy of this game less than 48 hours ago I&#8217;m pretty sure Dragon Age is the one. It brings back memories of games like Neverwinter Nights mixed with Baldurs Gate and maybe a hint of Mass Effect; all very distinctly BioWare games. The only thing letting it down at the moment for me is the lack of camera zoom and keyboard/mouse support for the PS3 version (all of which wouldn&#8217;t be an issue if I had brought the PC version of the game as the sales dude advised.)</p>

			<content:encoded><![CDATA[<p>You will need to have cmake and build-essentials installed:</p>
<p><code>sudo apt-get install cmake build-essential</code></p>
<p>How To Install Player:</p>
<blockquote><p>Player provides a network interface to a variety of robot and sensor hardware. Player&#8217;s client/server model allows robot control programs to be written in any programming language and to run on any computer with a network connection to the robot. Player supports multiple concurrent client connections to devices, creating new possibilities for distributed and collaborative sensing and control.</p></blockquote>
<p>Download the latest tar (I used player-3.0.0.tar.gz in this guide, if those numbers come up just change them with the version you are using)<br />
<a href="http://sourceforge.net/projects/playerstage/files/">http://sourceforge.net/projects/playerstage/files/</a><br />
Extract<br />
<code>tar zxvf player-3.0.0.tar.gz<br />
cd player-3.0.0</code><br />
Make a folder to store the build files<br />
<code>mkdir build<br />
cd build</code><br />
Configure using<br />
<code> cmake ../ </code><br />
Now make and install<br />
<code>make<br />
sudo make install</code></p>
<p>How To Install Stage:</p>
<blockquote><p>Stage simulates a population of mobile robots moving in and sensing a two-dimensional bitmapped environment. Various sensor models are provided, including sonar, scanning laser rangefinder, pan-tilt-zoom camera with color blob detection and odometry.</p></blockquote>
<p>Install some needed libraries:<br />
<code>sudo apt-get install libfltk1.1 pkg-config libtool </code></p>
<p>You will also need to install openGl:<br />
<code>sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev</code></p>
<p>You will need to download and install fltk-1.1.x and do the usual:<br />
(I used fltk-1.1.10rc3 found <a href="http://www.fltk.org/software.php">here</a>)<br />
<code>tar zxvf fltk-1.1.10rc3-source.tar.gz<br />
cd fltk-1.1.10rc3/<br />
./configure --enable-gl<br />
make<br />
sudo make install </code></p>
<p>Download and extract Stage (as you can see I used 3.2.2)<br />
<a href="http://sourceforge.net/projects/playerstage/files/">http://sourceforge.net/projects/playerstage/files/</a><br />
<code>tar zxvf Stage-3.2.2-Source.tar.gz<br />
cd Stage-3.2.2</code><br />
Make somewhere to store the build files<br />
<code> mkdir build<br />
cd build</code><br />
Configure:<br />
<code> cmake ../ </code><br />
Make and install:<br />
<code> make<br />
sudo make install</code></p>
<p>Currently this will output the following error:<br />
<code> collect2: ld returned 1 exit status<br />
make[2]: *** [libstage/stage] Error 1<br />
make[1]: *** [libstage/CMakeFiles/stagebinary.dir/all] Error 2<br />
make: *** [all] Error 2</code><br />
I will make an update on this post when I find out how to fix this, comment if you know how!</p>
