How to add “graphics.h” C/C++ library to gcc compiler in Linux

While trying c graphic programming on Ubuntu, I figured out that graphic.h is not a standard C library and it is not supported by gcc compiler. So I am writing this article to explain the process.

If you want to use graphics.h on Ubuntu platform you need to compile and install libgraph. It is the implementation of turbo c graphics API on Linux using SDL.
You can download it from here libgraph

Step by Step Instructions:

STEP 1: First install build-essential by typing
```
sudo apt-get install build-essential
```

STEP 2: Install some additional packages by typing

sudo apt-get install libsdl-image1.2 libsdl-image1.2-dev guile-1.8 
guile-1.8-dev libsdl1.2debian 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 extract the downloaded libgraph-1.0.2.tar.gz file.

STEP 4: Goto extracted folder and run following command

./configure
make
sudo make install
sudo cp /usr/local/lib/libgraph.* /usr/lib

Now you can use graphics.h lib using following lines:

int gd = DETECT,gm; 
initgraph (& gd,& gm,NULL);

Example code:

// C code to illustrate using 
// graphics in linux enviornment 
#include<stdio.h> 
#include<stdlib.h> 
#include<graphics.h> 
int main() 
{ 
    int gd = DETECT, gm; 
    initgraph(&gd, &gm, NULL); 
  
    circle(50, 50, 30); 
  
    delay(500000); 
    closegraph(); 
    return 0; 
}
