Install libgraph in Linux

Install libgraph library in GCC

Step #0. Go to Super User Mode in Terminal
Use sudo for Ubuntu, Zorin, Uber Student, Ultimate...
su for others.

Step #1.Install the following in Synaptic Package Manager

• build-essential
• libsdl-image1.2
• libsdl-image1.2-dev
• libsdl-ttf2.0
• guile-1.8-dev
• guile-1.8 

In Debian based linux It can be done by running following command line in terminal:

sudo apt-get install  build-essential 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 #2. Download and Extract libgraph then run inside libgraph... directory in Super User Mode 

• ./configure
• make
• make install

Step #3  Include graphics.h in your C program . Initialize the graphics system by

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

Step #4 you need to copy all the libgraph shared files from /usr/local/lib to /usr/lib

• cp /usr/local/lib/libgraph.* /usr/lib

Compile : gcc filename.c -lgraph

Example:

#include<stdio.h>

#include<graphics.h>

int main()

{

 int gd=DETECT,gm;

 initgraph(&gd,&gm,NULL);

 int i,x=10;

 char str[3]="0"; 

 setbkcolor(WHITE);

 setcolor(12);            //outline heart

 circle(50,50,40);

 circle(110,50,40);

 line(22,80,80,140);

 line(80,140,138,80);

    

 floodfill(50,50,12);     //fill heart 

 floodfill(110,50,12);

 floodfill(80,50,12);

 floodfill(80,100,12);

 getch();

 closegraph();

 return 0;

}
