Installing graphics.h in Linux Ubuntu

STEP- 1
Make sure you have the basic compilers installed.
You need the build-essential package. For this, run the command:
> sudo apt-get install build-essential
> sudo apt-get install g++
STEP- 2
First we need to install a hand full of packages. You can simply run the following command and get it all done.
> sudo apt-get install libsdl-image1.2
> libsdl-image1.2-dev
> guile-1.8
> guile-1.8-dev
> libsdl1.2debian-all
> libart-2.0-dev
> libaudiofile-dev
> libesd0-dev
> libdirectfb-dev
> libdirectfb-extra
> libfreetype6-dev
> libxext-dev
> x11proto-xext-dev
> libfreetype6
> libaa1
> libaa1-dev
> libslang2-dev
> libasound2
> libasound2-dev
STEP- 3
Now, download libgraph.
Copy the file libgraph-1.0.2.tar.gz to our home folder. Right click on the file and select Extract here.
Open a terminal and run the following commands, one by one.
> cd libgraph-1.0.2
> ./configure
>  sudo make
> sudo make install
> sudo cp /usr/local/lib/libgraph.* /usr/lib

STEP- 4
Now you’re ready to compile your C++ program! 
$ g++ program-name.cpp -o program-name -lgraph
$ ./program-name

Installing eclipse in Linux Ubuntu

First of all, you need to check whether you have java installed on your system. You can check by using the command:
java -version
If java is not installed, then you should install it by doing
sudo apt-get install default-jre
Afterwards, download Eclipse from the download section of the official website (http://www.eclipse.org/downloads/). Remember to choose the correct package for your architecture (32bit or 64 bit). The package will have the name:
eclipse-standard-kepler-SR1-linux-gtk-x86_32.tar.gz
or
eclipse-standard-kepler-SR1-linux-gtk-x86_64.tar.gz
After you have downloaded the correct package, extract the eclipse.XX.YY.tar.gz using

tar -zxvf eclipse.XX.YY.tar.gz

switch to root user:

sudo -i

Copy the extracted folder to /opt

cp -r eclipse.XX.YY /opt

Create a desktop file and install it:

gedit eclipse.desktop

Copy the following to the eclipse.desktop file.

[Desktop Entry]
Name=Eclipse 
Type=Application
Exec=eclipse
Terminal=false
Icon=eclipse
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE;
Name[en]=Eclipse

Run the following command to automatically install it in the unity:

desktop-file-install eclipse.desktop

Create a symlink in /usr/local/bin using

cd /usr/local/bin
ln -s /opt/eclipse/eclipse

For an eclipse icon to be displayed in dash, eclipse icon can be added as

cp /opt/eclipse/icon.xpm /usr/share/pixmaps/eclipse.xpm

How to Install OpenGL/Glut libraries in Ubuntu 12.04

The first step is to install the development libraries of OpenGL/Glut in Ubuntu:-
#  sudo apt-get install freeglut3 freeglut3-dev
For newer versions of Ubuntu (>= 11.10) you have to install another package because the linker does’t link anymore.
#  sudo apt-get install binutils-gold
Now create a test file (test.c) save it :
EXAMPLE:

#include <GL/glut.h>//Drawing funciton
void draw(void)
{
//Background color
glClearColor(0,1,0,1);
glClear(GL_COLOR_BUFFER_BIT );
//Draw order
glFlush();
} //Main program
int main(int argc, char **argv)
{
glutInit(&argc, argv);
//Simple buffer
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB );
glutInitWindowPosition(50,25);
glutInitWindowSize(500,250);
glutCreateWindow(“Green window”);
//Call to the drawing function
glutDisplayFunc(draw);
glutMainLoop();
return 0;
}

Compile the file linking the OpenGL/Glut libraries:-

#  cd /Desktop

#  gcc -lGL -lglut test.c -o test

#  ./test

Finish

How to install and use Eclipse CDT for C/C++ programming

Follow the link.... 

http://www3.ntu.edu.sg/home/ehchua/programming/howto/EclipseCpp_HowTo.html

OR

Step 1: Install Eclipse C/C++ Development Tool (CDT)

1. Two ways to install CDT, depending on whether you have previously installed an Eclipse:
If you have already installed "Eclipse for Java Developers" or other Eclipse packages, you could install the CDT plug-in as follows: Launch Eclipse ⇒ Help ⇒ Install New Software ⇒ In "Work with" field, pull down the drop-down menu and select "Kepler - http://download.eclipse.org/releases/kepler" (or juno for Eclipse 4.2; or helios for Eclipse 3.7).
In "Name" box, expand "Programming Language" node ⇒ Check "C/C++ Development Tools" ⇒ "Next" ⇒ ... ⇒ "Finish".

2. If you have not install any Eclipse package, you could download "Eclipse IDE for C/C++ Developers" from http://www.eclipse.org/downloads, and unzip the downloaded file into a directory of your choice.

Step 2: Configuration 

You do NOT need to do any configuration, as long as the Cygwin or MinGW binaries are included in the PATH environment variable. CDT searches the PATH to discover the C/C++ compilers.

Writing your First C/C++ Program in Eclipse

Step 0: Launch Eclipse

Start Eclipse by running "eclipse.exe" in the Eclipse installed directory.
Choose an appropriate directory for your workspace (i.e., where you would like to save your works).
If the "welcome" screen shows up, close it by clicking the "close" button.

Step 1: Create a new C++ Project

For each C++ application, you need to create a project to keep all the source codes, object files, executable files, and relevant resources.
To create a new C++ project:
Choose "File" menu ⇒ "New" ⇒ Project... ⇒ C/C++ ⇒ C++ project.
The "C++ Project" dialog pops up.

In "Project name" field, enter "FirstProject".
In "Project Types" box, select "Executable" ⇒ "Empty Project".
In "Toolchains" box, choose your compiler, e.g., "Cygwin GCC" or "MinGW GCC" ⇒ Next.

The "Select Configurations" dialog appears. Select both "Debug" and "Release" ⇒ Finish.

Step 2: Write a Hello-world C++ Program

In the "Project Explorer" (leftmost panel) ⇒ Right-click on "FirstProject" (or use the "File" menu) ⇒ New ⇒ Source File.
The "New Source File" dialog pops up.

In "Source file" field, enter "Hello.cpp".
Click "Finish".

The source file "Hello.cpp" opens on the editor panel (double-click on "test.cpp" to open if necessary). Enter the following codes:

#include <iostream>
using namespace std;
 
int main() {
   cout << "Hello, world!" << endl;
   return 0;
}

Step 3: Compile/Build

Right-click on the "FirstProject" (or use the "Project" menu) ⇒ choose "Build Project" to compile and link the program.

Step 4: Run

To run the program, right-click on the "FirstProject" (or anywhere on the source "test.cpp", or select the "Run" menu) ⇒ Run As ⇒ Local C/C++ Application ⇒ (If ask, choose Cygwin's gdb debugger) ⇒ The output "Hello, world!" appears on the "Console" panel.
NOTE: You need to create a new C++ project for EACH of your programming problems. This is messy for writing toy programs!
