Installing from Source (Linux)
Software name : VLC
Homepage : http://www.videolan.org/vlc/
Software version used for this installation : 0.84
Operating System use for this installation : Debian (this process will work on any version of Linux)
Recommended Hardware : 300MHz processor
Downloading
First, get the sources. To do this you should visit the VideoLan website (http://www.videolan.org) and download the sources from the website. At the time of writing the URL for downloading VLC source is this:
http://www.videolan.org/vlc/download-sources.html
Make sure you download the sources to somewhere you can access using a terminal ('shell'). If you do not know how to use a terminal then please also read up on this otherwise the following is going to be very difficult to follow. If you know how to use the terminal then copy the sources to the directory you are currently in or change your current working directory to the directory where the sources are.
The sources, once downloaded, will need to be 'unpacked'. This means that they source code has been compressed and needs to be uncompressed. Most Linux applications have their source code compressed in the tar and gzip formats. You can recognise this type of compression if the file you downloaded ends with the suffix:
.tar.gz
In this case the source code I have downloaded is named vlc-0.8.4a.tar.gz
Before I start the installation I need to check the sources are in the same working directory as my terminal. To do this I type ls and I shoudl see something like this in my termial:
The above is just an example. The information will vary in your window, but it is critical that you see the sources you downloaded in the list of files.
Now we will decompress the files. To do this we need to use the tar application. If your version of Linux doesn't have this then you will need to first download and install it. The best way to find out if it is installed is just to type tar and press return. You should see somehting like this:
The above message is actually an error message, but if you see it ignore the message as we only executed the command to check if tar was installed. If tar is installed then type the following:
tar -zxvf vlc-0.8.4a.tar.gz
Make sure you replace vlc-0.8.4a.tar.gz with the name of your sources file. If all is well you will see a lot of information shoot through the terminal which is simply a list of all the uncompressed files. These files are the source code and you will now need to transform the source code into the VLC program. This process is called compiling. However before you compile VLC from the source code you need to configure VLC. This might seem strange, software should be configured after it has been installed right? Well, yes, but also in Linux you can enable or disable many options to be included into the program when you compile it. This process actually changes the software so that it includes or excludes different functional components. This process is also called configuring.
Configure
The way you install software on Linux is dependanton the type of Linux you may have. There are many types of Linux and each has its own way of installing software using what is known as a Package Manager. A Package Manager is a system dedicated to downloading and installing software on your computer, usually in an semi-automatic way.
This can be really good if you don't care about the way a software is configured. However in Linux you can change the configuration of a software dramatically in the install process. It is possible, for example, to enable and disable many options in VLC when you prepare the software for installation. Generally speaking, automatic install processes don't always give you so much control over the install options. Notably the Gentoo version of Linux gives you a lot of control. However with Debian, Ubuntu and Redhat you will have a default install with default options turned on and off. Most of the time this will probably be ok. However if you need a 'special' function enabled in a software it is often only available if you enable it during installation, otherwise the functionality you require just simply won't exist.
VLC has a lot of options you can include or exclude when you go through the pre-compiling configure process. The configure process is triggered by the configure command. However this command can also give you feedback so you know what the options are before you actually configure the application. To check the configure options of (almost) any source type the following from within the uncompressed source directory:
./configure --help
This will give you an enormous amount of information in the terminal. Probably the information will flow by faster than you can read it and you will be left with the tail of the data. To control this better, try the following command :
./configure --help | less
This command is actually two commands combined. The less command allows you to control the information flowing past on the screen by the use of the page up and page down buttons on your keyboard. The character in between the two commands is called the pipe and it allows commands to be combined. It might be that you do not have less installed which means that the above is quite useless to you. In this case you can try the following:
./configure --help | more
The more command displays a page of text and then waits for you to press the space bar before showing you the next page. If you don't have any luck with the above two suggestions it might be that you don't have either installed, in which case it is a good idea to install them.

The process of installing from source can be a little experimental. You may find that certain libraries are required that you don't have installed on your computer. For example, the following command will disable ffmpeg, libmpeg2, and skins2.
./configure --disable-ffmpeg --disable-libmpeg2 --disable-skins2
The above command should then return alot of information in the terminal and finish with some lines looking like this:
Make
If all is ok then you will need to run the make command and make install. You can do this on one command line in conjunction with the sudo command. sudo gives you the permissions to install software. If you don't have the rights to do this (you get an error or message when using sudo) then you will need to contact your system adminsitrator. If you the system administrator and don't know how to do this then you may need to read up on how to set up sudo or su commands. The following command will compile and install your newly configured VLC:
sudo make;makeinstall;
If, however when you get some errors when installing VLC it is probably due to missing libraries. For example, if the ./configure command gives an error like this:
configure: error: Missing header file ffmpeg/avcodec.h
This means that a header file is missing. Usually this means you need to install the header files, each version of Linux deals with these seperately and you will need to search online to find the right solution. The best method I have found is to copy the error message into a web search and see what postings exist online which discuss the same error.
