Ive read and pondered upon lots of blogs and posts regarding the topics "20xx is the year of the linux desktop" , "linux is not yet ready for the desktop" etc etc.I guess the answer to all such questions is personal in nature. I mean id say "try and find out". I started using a GNU/Linux distribution about 8 months ago. Since then my aim was to do whatever stuff i was doing on XP, on GNU/Linux and maybe find stuff i couldnt do on XP. Thats how i approached/read about GNU/Linux though i later found out that, that approach isn't exactly right, as i was merely "reducing" GNU/Linux to a windows replacement, while its actually a whole another approach to computing.
Anyways, since i joined engineering if there was one thing i didnt like at all, then it was the "Blue Screen Of Death" or the Turbo C interface. Since s3 i never used Turbo C at home. I've always preferred Visual Studio or Dev C++ over Turbo C. I just didnt like the interface. This dislike of turbo C didnt however hamper my coding functionalities in other IDE's as they always had what i wanted. After moving to GNU/Linux i was able to do the same programs and compile them using G++. But s7 is were the problem starts. Now i gotta "computer graphics" lab which makes extensive use of the "graphics.h" library. I had heard rumours earlier that it wasnt available in all IDE's and to my dismay i found out that it wasnt there in GNU/Linux either. Another problem was that since the functions it included involved direct access to the hardware merely copying the graphics.h header to the library folders wouldnt help. As always google helped. Stumbled upon the blog of a
person who was in the same situation as I am and he had found a solution. The answer to my problem was a set of libraries called libgraph which wraps around the
SDL API.His blog did contain steps to install in debian but it didnt work for me coz of minor hiccups. SO i spent sometime and finally succeeded in getting it to work on my ubuntu feisty install. I just thought i'd post it here so that google drops this in front of another seeker :)
Step 1: Installing dependencies
run
sudo apt-get install build-essential to make sure you have installed all necessary compiler tools
Now comes the real achy part. Open synaptic and install the following packages
libsdl-image1.2
libsdl-image1.2-dev
guile-1.8
guile-1.8-dev
libsdl1.2debian-arts
libartsc0-dev
libaudiofile-dev
libesd0-dev
libdirectfb-dev
libdirectfb-extra
libfreetype6-dev
libxext-dev
x11proto-xext-dev
libfreetype6(upgrade)
libaa1
libaa1-dev
libslang2-dev
libasound2
libasound-dev
You can install them in a single go by adding all the above package names(separated by a black space) to the end of
sudo apt-get install Even if it asks you to uninstall some already installed stuff, tell it to proceed. After all this is over. Download this file onto your home folder:
libgraph-1.0.1Right click on the file u just downloaded and click "Extract here"
open terminal and navigate into the folder u just extracted the file contents into by running
cd libgraph-1.0.1
Now run the following commands one after the another. Proceed to the next command only if the preceding command executes without any errors.
./configuresudo makemake install
If you get any errors during the "sudo make" step, paste it in the comments section of this post.
Now technically install is over. Try writing a simple program including graphics.h. Declare the values of gd and gm and call initgraph as follows
int gd,gm=VGAMAX; gd=DETECT; initgraph(&gd,&gm,NULL);
and when compiling using g++ add an extra paramter
-lgraph
i.e if you are compiling a program dda.cpp in the terminal u type in
g++ dda.cpp -o dda.o -lgraph
And execute the program by runnung ./dda.o
If on compile it gives u an error that says "could not load shared libraries" or something like that just run the following command and it should fix it
sudo cp /usr/local/lib/libgraph.* /usr/lib
I also read somewhere that graphics.h dosen't have ANY practical use in today's world and that its only "use" now is to help students learn to apply different algorithm's they have to study in a paper called "Computer Graphics"
