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;
}
