How To Update Your PCLinuxOS Repository Using Synaptics

It's been quite easy and simple to add an application onto Linux distribution these days. Since most of Linux distribution has what they call repository to provide support for its distribution. It's even more easier with the graphical package manager included in its distribution.

Some of them even have mirrored their repository to local website on certain region. And some of them provide a limited repository during their distribution release in a form of DVD or extra CD companion.

In this post, I'd like to share my experience on updating repository in PCLinuxOS. Let's get started step-by-step.

  1. Make sure you are connected to the internet before going on to the next step. Otherwise, it won't work.
  2. Open your Synaptics package manager. Click KMenu (or press Windows logo on your keyboard), point to System, Configuration, Packaging, then click on Synaptics Package Manager.






  3. Type in your root password. I'll assume you're the administrator on your Linux machine.
  4. After the Synaptic window popped out, click Settings on the menu bar, then click Repositories.
  5. Another window will pop up showing you the list of repository mirrors available. Check on the box to enable it. Make sure it is the site closest enough to your local region.
  6. A little note. Do not remove the link on the last list, since it is for openoffice related packages.
  7. When you finish, click OK to close the window.
  8. Then on the main window, click Reload to get any changes you made loaded. Synaptic will download the package lists from the site you've checked before. it might takes several minutes depending on your internet speed.
That's all you need to do. You can install an application as usual, with the latest version of course. :)

    General Requirements for Solving Dependency Issue Before Installing Player/Stage

    There are always several packages required before installing an application on Linux operating system or at least, one. Since an application in Linux environment almost always never embed the dependency packages required upon its release. Take for example, installing Player/Stage. Visit this website for more information about Player/Stage.

    Depending on the distribution, each Linux distribution require different packages installed before installing the same application.

    I've been wandering the internet to solve the dependency issues while installing Player/Stage on my Linux machine. I've tried installing in onto Mandriva 2008 and 2009, OpenSuSE 9.3 and 10.0, and lastly onto PCLinuxOS.

    I couldn't install Player/Stage on Ubuntu, since my machine cannot boot Debian-based Linux distribution. Although, most of the information available on the internet are about installing Player/Stage on Ubuntu.

    Hence, I thought I need to write a more general information regarding requirements before installing Player/Stage, regardless of the distribution.
    Once again, depending on your distribution, the name of the packages might differ.

    gcc42-fortran, gcc-fortran, libgfortran42 (or g77 or any fortran compiler)
    gcc, g++
    opencv
    libusb, -devel
    libconfig (install the most recent version)
    imagemagick, -devel, (or libmagick10, libmagick++10, libmagick10-devel)
    libopenssl, -devel, openssl, -certs
    libjpeg, -devel, libpng, -devel, libjasper, -devel, zlib, -devel, libtiff, -devel
    libdc1394, -devel, libraw1394, -devel
    sed
    gsl
    libtool (or libltdl3, -devel)
    boost, -devel (might be one of these:
        libboost-dev
        libboost-thread1.33.1
        libboost-thread-dev
        libboost-signals1.33.1
        libboost-signals-dev)
    swig
    gawk
    pkg-config
    python
    gtk, gtk2, -devel and gdk (the gtk is a must before installing stage)
    freeglut, -devel (this is the OpenGL library)
    cmake
    fltk, -devel
    geos or libgeos
    statgrab
    gnomecanvas (or libgnomecanvas)
    xmms-config
    gtk, -devel, (or gtk+2, -devel, gtk2, -devel)
    howl
    ffmpeg
    ode (this package is a must before installing gazebo)

    I've wrote them on a file and uploaded it to my Google Docs. You can read it there.

    Write to me if you find an error or there is something needs correction. Happy installing Player/Stage.

    Have You Try to Google Your Name?


    Have you try to google your name? Wha..., google my name!?

    I google my web-name (I don't think pen name is correct for internet) today and I returned a lots of result. More than 1000 entries! Yay! For someone like me, that's a lot.

    Althought, since it's just a web-name a.k.a. short nickname, it did return some unrelated web-name from someone else.

    But, above all, I found it useful to remind you of what you have done over the internet. I remember again the forum where I have posted replies or comment; thus, forums which I actually have registered with.

    And also, I found my previous domains subbed under free domain service website. Even my old email account!

    It's kinda nostalgic. But to think that there are other persons out there to have the same web-name, I feel kinda cautious. He or she might have account to certain websites that people find disturbing.

    I also afraid that if my friends searched my web-name and found it within those websites, they might think I was not as they know I was and I've been lying to them.

    Anyway, it was just for fun to google your name, if you friend ask you just tell them the truth. It's always good to be honest toward for friendship, isn't it?
