Installation on Ubuntu 9.04
Update package index first
$ sudo aptitude update
Install required packages
$ sudo aptitude install codeblocks codeblocks-contrib
For code development, you'll also need some additional packages. Run
$ sudo aptitude install build-essential gdb subversion
$ sudo aptitude install automake autoconf libtool
$ sudo aptitude install libgtk2.0-dev libxmu-dev libxxf86vm-dev
These package are for programming with the wxWidgets GUI toolkit. Code::blocks itself is a pure wxWidgets product.
$ sudo aptitude install libwxbase2.8-dev wx2.8-headers libwxgtk2.8-dev wx-common
------------------------------
Then start the codeblocks IDE from the Application -> Programming menu or type:
$ codeblocks
The first launch will ask the compiler name. The default c/c++ compiler in Linux is "GNU GCC compiler".
Select it. See picture:
------------------------------
Below are some important notes. Especially read the notes 1- 5.
Use the (glut) freeglut library to develope portable OpenGL applications. Read note 1.
Code::Blocks has a GLUT project wizard. Use it to create your first OpenGL project. Build & run.
Some important notes.
Alguns comentários importantes.[ Note 1 ]
If you want to develope OpenGL (glut...) applications, install FreeGlut first :-)
Click this link... or type the command manually.
$ sudo aptitude install freeglut3 freeglut3-dev
Ceate a new project and select the "GLUT project" in the project wizard.
An important tip: Say: /usr when it asks the "Please, Select GLUT's location:".
See picture
Read also the Note 5) below.
[ Note 2 ]
If you want to develope GLFW applications, install GLFW first ( http://glfw.sourceforge.net/ )
Read also this posting...
The Ubuntu's freeglut library is more up-to-date than GLFW.
[ Note 3 ], c-cpp-reference:
Do not forget to install the "c-cpp-reference" manuals. Run this command:
$ sudo aptitude install c-cpp-reference
OR use your Synaptic Package Manager and get the package. It will put some help files in the /usr/share/doc/c-cpp-reference/ directory.
Start Firefox and point it to /usr/share/doc/c-cpp-reference/index.html

[ Note 6 ], wxWidgets examples !
Define wxWidgets... Homepage...
WxWidgets is a multi platform GUI toolkit.
First, install the wx2.8-examples package
$ sudo aptitude install wx2.8-examples
The package puts the examples into /usr/share/doc/wx2.8-examples/examples/ directory. It's a compressed tar-ball which you have to unpack/untar.
Run the "unpack_examples.sh" script (in the same directory) to unpack the samples to your $HOME directory.
For example, run:
$ /usr/share/doc/wx2.8-examples/examples/unpack_examples.sh $HOME/wxwidgets2.8
And it will unpack & put the samples into your $HOME/wxwidgets2.8/samples/ folder.
You can now compile and run the examples directly from the command line.
The compilaton requires wxWidgets' development headers and libraries. You will need these packages; libwxbase2.8-dev wx2.8-headers libwxgtk2.8-dev
As an example let's compile the /popup sample code. First, move to the samples/popup/ directory
$ cd $HOME/wxwidgets2.8/samples/popup/
Compile the project.
$ make
Run it
$ ./popup
./ means the current directory. Yu must include it, otherwise the shell will not find the program, because by default, the current directory is NOT in the $PATH.
$ echo $PATH
Now, try to compile and run the other wxWidgets examples as well.
Study also the wxWidgets' documentation package wx2.8-doc.
$ aptitude search wx2.8-doc
wx2.8-doc - wxWidgets Cross-platform C++ GUI toolkit (documentation)
Install it and list the documentation (html) files
$ dpkg -L wx2.8-doc
$ dpkg -L wx2.8-doc | grep index
And then open the index.html in Firefox.
Of course, the documentation is available online too...

[ Note 7 ], Necessary packages to develope SDL-applications.
Define SDL... Homepage...
SDL stands for Simple DirectMedia Layer...
It's a framework to greate portable 2D graphics applications. It also supports OpenGL.
First, list all packages that belong to the SDL family.
$ aptitude search libsdl | grep dev
The "-dev" packages contain the header (include) files and dynamic libraries for app development. You'll need them.
Install at least these basic packages. These give you a good start.
$ sudo aptitude install libsdl1.2-dev libsdl-image1.2-dev libsdl-sound1.2-dev libsdl-mixer1.2-dev
However, the most basic apps need only the "libsdl1.2-dev".
Then create a basic SDL-application via the Code::Blocks' project wizard (select SDL project).
Note: The SDL's sound, image and mixer functions have their own libraries and include files which you must add to your project.
And add these includes to your code:
#include
#include
#include
Additional information:
This command will list the installed SDL related packages
$ dpkg -l | grep libsdl
This command will list the installed SDL related libraries
$ ls -l /usr/lib/libSDL*so
This command will list the available include files (most of them are included through the SDL.h)
$ ls -l /usr/include/SDL/*
This command (already in your project's build options) finds the library PATH, library name and the include PATH + possible debug options.
All well done libraries have this xxx-config thing.
$ sdl-config --cflags --libs

What manual pages does Ubuntu (or any other distro) offer?

manpages - Manual pages about using a GNU/Linux system
manpages-dev - Manual pages about using GNU/Linux for development
manpages-posix - Manual pages about using POSIX system
manpages-posix-dev - Manual pages about using a POSIX system for development
Install all manpages*dev packages
$ sudo aptitude install manpages-dev manpages-posix-dev
Note: This command vill tell you what manual sections (1 - 8 ) the package covers.
$ aptitude show manpages-posix-dev

[ Note 18 ],
Learn by studying the existing source code of applications in the Ubuntu distribution.
A real world example: How do I implement a code that can distinguish between real files and file links (symbolic and hard links)?
Answer: Study the source code of the "readlink" command.
But first, what package the readlink belongs to?
$ apt-cache search readlink
coreutils - it is. The GNU core utilities package.
[ Note: You must activate the source code repository in the Software Sources dialog. You will find it in the Administration menu. Activate or add the deb-src lines.
Refresh the package list in your pc (sudo apt-get update) ], then
Apt-get the source.
$ apt-get source coreutils
$ cd coreutils-6.10
Locate the "readlink" function and all places it's been called from
$ grep -R readlink *
And study the code ;-)
I took this example from Ubuntuforums.org, post 5041297...
-------------------
A second example.
I want to make some improvements to the GNOME's Disk-Mounter applet. It's an applet you have on the desktop panel.
Where's the source? Some digging reveals that the package name is "gnome-applets".
Get the source.
$ mkdir -p $HOME/code && cd $HOME/code
$ apt-get source gnome-applets
Use build-dep to install dependencies so we can compile the code.
$ sudo apt-get build-dep gnome-applets
$ cd gnome-applets-2.26*
Configure and compile with the normal mantra; ./configure && make.
Install with sudo make install.
The code of the Disk Mounter is in
$ cd drivemount
Make your changes and type "make" to recompile it.
Type "sudo make install" to install it.
[ Note 19 ], I want to compile program XX from source, but it has too many dependencies.
Study the above note (Note 18).
Use build-dep to install *-dev files and dependencies (if the repo has a package for it).
$ sudo apt-get build-dep XX
Then compile XX from source.

10X alot !
u r my man !
just had a trouble to start sdl with codeblocks..
hope to read and get the help i need..
i'll check it out later.
I have heard about the Visual C++ that People make fewer mistakes in consistent environments, Programmers can go into any code and figure out what's going on, People new to C++ are spared the need to develop a personal style and defend it to the death, People new to C++ are spared making the same mistakes over and over again, Programmers have a common enemy.
@magnesium : what is the joy of programming if u can't read the code of other people. I think thats why FSF and opensource exist. they make programmers happy by giving them eternal joy. by using visual c++, we are restricted to windows platform. i think for code completion, netbeans is the best IDE for windows, macosx, linux. but codeblocks is really nice for programming on linux too.

Rooparam Bhakar
