I had been searching for compilation and debugging of the VLC source code in eclipse IDE for a long long time. I could not get much success though. But, finally I got it by myself. And now, I want to share my experience with others, so that guys like me can take the advantage and explore further.
Here is the step by step process of how to compile and debug the source code of VLC media player in eclipse IDE on Ubuntu 10.04.
Prerequisites:
1. eclipse IDE for C/C++
[can be downloaded from: http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/helios/SR2/eclipse-cpp-helios-SR2-linux-gtk.tar.gz ]
2. source code for VLC media player
[can be downloaded from: http://sourceforge.net/projects/vlc/files/1.1.9/vlc-1.1.9.tar.bz2/download ]
3. Working Internet connection.[probably you may have to download some libraries/packages]
Steps:
Step 1: Download and extraction of code:
1.1: Download the source code of vlc and save it somewhere [e.g /home/<username>/Downloads]. I am using the latest one [i.e vlc-1.1.9.tar.bz2 ].
1.2: Extract it. To extract...
-open terminal: Applications-> Accessories-> Terminal
-go to that directory in which source code is kept.-and run the command: $tar -xvf vlc-1.1.9.tar.bz2
-this will extract the contents into folder vlc-1.1.9
Step 2: Configure the source code: this step may take several iterations while configuring. Why?, because you may have to resolve some errors while configuring
2.1: to configure...
-go to the folder vlc-1.1.9
-run the command: $./configure
-if no errors appear, then you are done with configuring the code. Move on to the next step.
-if there are errors, then resolve those error by some means and again run $./configure command.
Error examples: In my case one of the errors was...
To resolve this error, I downloaded and installed libdbus-dev library. For that I did the following...
-open Synaptic Package Manager [System-> Administration-> Synaptic Package Manager]. It will need root/admin password. And enter the library name which needs to be installed.
-right click on the selected library and select 'Mark for Installation'.
-After that click on Apply button[green tick].
-A summary dialog box will open. Click on apply.
-After change have been applied. Run the $./configure command. If still errors appear. Do repeat the same process until no errors appear and configuration is successful.
Note: if that doesn't solve the purpose, you may try disabling that library/package by running $./configure –disable-<pack/lib name1> –disable-<pack/lib name2> –disable-<pack/lib name3> ... .
Step 3: Creating and compiling vlc project in eclipse.
3.1: Download and extract the eclipse file [eclipse-cpp-helios-SR2-linux-gtk.tar.gz] to a folder. Go to eclipse folder and run eclipse executable to run the eclipse IDE.
-Select C/C++ -> C Project, and click Next.
-Select project type as Makefile Project-> Empty Project
-Select tool chain as Linux GCC and click on Finish button.
3.4: Importing source code:
-Right click on the project name [vlc-1.1.9] in Project Explorer [left pane] and select Import... . A wizard will open.
-Select General->File System and click on Next button.
-Select from directory of configured source code.
-Check the check-box to select all the files inside source folder.
-Click Finish button.
3.5: Building the source code: Once the indexing is done...
-Go to Project-> Build All. And the code will start building...
3.6: Running the vlc after build.
-Right click on the project name [vlc-1.1.9] in Project Explorer [left pane] and select Run As->Run Configurations... . A wizard will open.
-Click on Search Project... button and select vlc as below...
This will run the vlc player.
And now, as you have vlc-1.1.9 source code configured on your eclipse IDE on Ubuntu 10.04(lucid), you can go through the code, explore it, play with it, and debug it accordingly.
Enjoy!!
Please write your comments, suggestions, inputs as they are always welcome.
Thanks, this was very helpful for a relatively complete newbie with Eclipse and VLC

Thanks for the nice guide.
ReplyDeleteI followed the steps you suggested but I get this error when I try to run build all:
Description Resource Path Location Type
fatal error: libavutil/audioconvert.h: No such file or directory vlc line 44 C/C++ Problem
Do you know what is the reason?
I checked the libavutil is installed.
Thanks,
TJ
thanks nice guide
ReplyDeleteSo far correct but in project properties you have to set c/c++ to
ReplyDelete../vlc/build
that's good. i hope it suite with my open source software assignment at the university. iaa
ReplyDeletethanks alot for that explination
ReplyDeletea question
where is the main code ( int main() )
thanks
Thanks alot
