In this tutorial, we will be discussing a program to understand how to add “graphics.h” C/C++ library to gcc compiler in Linux.
To do this we are required to compile and install the libgraph package.
This includes install build-essential and some external packages
>>sudo apt-get install build-essential >>sudo apt-get install libsdl-image1.2 libsdl-image1.2-dev guile-2.0 guile-2.0-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
Then setting the path in the extracted files
>>sudo make install >>sudo cp /usr/local/lib/libgraph.* /usr/lib
Example
#include<stdio.h>
#include<stdlib.h>
#include<graphics.h>
int main(){
int gd = DETECT, gm;
initgraph(&gd, &gm, NULL);
circle(40, 40, 30);
delay(40000);
closegraph();
return 0;
}Output
