How to install Libgraph on UBUNTU

●This project is not part of the GNU Project. libgraph is an implementation of the TurboC graphics API (graphics.h) on GNU/Linux using SDL. The library requires SDL for primitive graphics and SDL_image (to blit fonts). Functions for text display are based heavily on code "borrowed" from Karl Bartel's SFont library.

● The library is not very powerful or flexible. It is probably not suitable for use in production-quality applications. I see it more as a simple, easy-to-use 2D graphics interface - could be used for simple prototyping, visualization or studying graphics algorithms. It is simplified library to run graphics programs in C.

It works efficiently with open source C compiler gcc. It is required to add the sdl-libgraph library to current existing gcc

Prerequisite: Internet Connection

You need to install some basic packages. Open terminal and exicute the following commands on terminal.

1) sudo apt-get update 

                 To update your basic packages

2) sudo apt-get install build-essential

                 For installing essential packages.

3) sudo apt-get install libsdl-image1.2 libsdl-image1.2-dev guile-1.8 guile-1.8-dev 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

                 For installing lib packages

4) Now, download libgraph from: 

(http://download.savannah.gnu.org/releases/libgraph/libgraph-1.0.2.tar.gz). Then copy the file libgraph-1.0.2.tar.gz to our home folder. Right click on the file and select Extract here.

5) 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+

Now you are ready to compile your program!

● Write your program using any editor and save.

● Open the terminal for the specified folder and then run with:

gcc MyProg.c -lgraph (for C program)

g++ MyProg.cpp -lgraph (for C++ program)

./a.out

● Once all this installation process is done, you don't need to follow this process again and again. Just

compile and execute the program.
