The solution for doing graphics programming in ubuntu is:
libgraph - library providing the TurboC graphics API ( graphics.h) in Linux using SDL.
For using this , you need to follow some simple steps as mentioned below:
First of all, you need to install the dependencies so that all the required compiler tools gets installed. For that you need to run the given command on the terminal:
sudo apt-get install build-essential
Next you need to install some packages. They are: libsdl-image1.2, libsdl-image1.2-dev, guile-1.8 and guile-1.8-dev. For that run the given command at the terminal:
sudo apt-get install libsdl-image1.2 libsdl-image1.2-dev guile-1.8 guile-1.8-dev
Now, download and install libgraph-1.0.2.tar.gz from the link :
Download this file in any folder and extract it in the home folder or on the desktop wherever you want.
Open the terminal and navigate to the folder where you have extracted libgraph-1.0.2 with the help of cd command. Install this using the commands given below:
./configure (Return)
sudo make (Return)
sudo make install (Return)
After this you can start your C graphics programming in linux. Now try writing a simple C graphics program by including the header file "graphics.h". You can do the programs as you in TURBO C.
For writing the programs you can use the "gedit" tool in ubuntu. For compiling the programs, navigate to the source program folder and use the following command:
gcc filename.c -lgraph
For executing the program, use the command ./a.out
The error “./a.out: error while loading shared libraries: libgraph.so.1: cannot open shared object file: No such file or directory” can be solved by
sudo cp /usr/local/lib/libgraph.* /usr/lib
If you still have some furthur issues related to this post, post it here.
some error occurring while installing .....so I am unable to use it.

I get this message and the graph closes. Please help!
email:whisperingwind.sanjay@gmail.com
In turbo c++, i use :
ReplyDeleteint gdriver=detect,gmode,errorcode;
initgraph(&gdriver,&gmode,"C:\\tcplus\\BGI");
so whats the equivalent code here??
libgraph is so much equivalent to Turbo C++. It had been introduced keeping in view the users comfortable with Turbo C++.
ReplyDeleteSimply use:
int gd=DETECT,gm;
initgraph(&gd,&gm,"");
U don't need to specify any path in initgraph. Even in Turbo C++,u can avoid writing the path in initgraph() by copying the file EGAVGA.bgi from BGI folder and pasting it in Bin folder.
The message u gave here flashes on the terminal due to initialization of the graph while u r receiving inputs. Just initialize the graph after u have entered the inputs.
ReplyDeleteJust consider ur example.Perhaps u were drawing line by bresenham algorithm.....Take the inputs from the user (in this case the end points of the line) before initializing the graph(or calling initgraph()).
If still anything happens....make me know....
One more thing...use the kbhit() function and closegraph() at the end for closing the graph.
thanks a lot! I got it working...
ReplyDeletethanks buddy its wotking
ReplyDeletehi shekhar,after entering the values a flash screen pops up and closes immediately ,so how can i be able to see the out put????no error mesgs are being displayed.
ReplyDeleteone more thing,,when i used conio.h its showing me error ---->no such file or directory<----
plzz help me get out of this ,,,chetan
conio.h is not available under libgraph...so just don't use it....
ReplyDeleteuse kbhit() or getch() function to see the output screen and then use closegraph() to close the graph.
write the following at the end of the program before return:
while(!kbhit());
closegraph();
This will do...if still u r unable to see the output, let me know..
Here a sample program for u. Try it..
#include
#include
int main()
{
int gd=DETECT,gm;
initgraph(&gd,&gm,"");
circle(100,100,50);
while(!kbhit());
closegraph();
return 0;
}
first include is stdio.h and the 2nd one is graphics.h...
ReplyDeletethank u shekar its working fine. i didn't expect such a quick repl from u,really thank u man.
ReplyDeletewhy should we use gcc filename.c -lgraph for compiling
ReplyDeleteisn't cc filename.c enough???(of course i did not get output using that command)
just clarify me, thanks in advance
gcc filename.c -lgraph is used to link the program with libgraph which contains graphics.h .
ReplyDeletecc instead of gcc will do but u need to append -lgraph at the end.
If u want a short command u can use
grc filename
For viewing the manual entry on libgraph, use the command " man libgraph ".

ReplyDeleteSDl window is small sized. How to get 640*480 graphics mode
ReplyDeleteFor 640*480 graphics mode, use the program statement:
ReplyDeleteint gd=DETECT,gm;
initgraph(&gd,&gm,"");
For further details on the enumerations used for graphics driver, see the documentation of libgraph. You can use 0 to 10 instead of DEFAULT. 0 gives the default enumeration.
When I am trying to compile file I got these errors
ReplyDelete/tmp/ccJKVMEj.o: In function `main':

collect2: ld returned 1 exit status
@Jayendra... Please post your program here. There's no problem related to the installation.
ReplyDeletethanks for grate blog
ReplyDeletecan we change then name of a.out
like if program is for circle then we can call circle.out
somthing
@GURU ... For that, you need to compile the program using the command:
ReplyDeletegcc filename.c -lgraph -o filename
And run it using "./filename". Quotes are not included in the command.
Consdering your example, the command for compilation would be "gcc circle.c -lgraph -o circle" and it can be executed using "./circle".
One more thing, the executable file can be generated with a name different from the source file using the command:
gcc filename.c -lgraph -o newfilename
and the program can be executed using the command:
./newfilename
One point to be noted in this case is that the .obj filename will be the same as the source file name.

Good Job Shekhar !!!
ReplyDelete@Situkangsayur..
ReplyDeleteI have tried this on Ubuntu 10.10 and it works fine. Try compiling it again. If the error persists , mail me the program so that i can have a look at it.
used your sample code:

ReplyDeleteHow to fill the rectangle with a color?
ReplyDeleteand how to make delay's in gcc for graphics programs?
how to draw rectangles of different line-widths?
ReplyDeleteRefer the documentation provided for graphics programming on the internet or some nice books. You will find everything there.
ReplyDeleteAs for filling a polygon flood filling method(recursive or non-recursive one) will do or you can make use of the others methods. C provides a built-in function for filling polygons (refer the documentation).
For making delay in gcc for graphics programs, make use of the delay() function. You can use any integral parameter for the delay function. Don't forget to include the necessary header files.
If still you have some problems send me your email id, i will mail you the programs for the same.
gcc doesn't include the DOS.H file which is neccessary for the DELAY function. What to do now?
ReplyDeletethanks a million sir , it worked for me too

i have cleared the input output buffer prior to initialising the graph using getchar(). i would really appreciate it if you could tell me how this can be solved.
@Soham - Initialize the graph after u have received the inputs.
ReplyDeletefantastic post buddy.... helped a lot... thank you so much..

ReplyDeletebut how to include "dos.h".
its not available in the packages.
do u have any way ???
dos.h provides functions for interrupts and system-level implementations in C under windows. Equivalent implementations can be achieved with the header file "signal.h" and various other header files present in the "/usr/include/sys" directory. Just check for the headers you need.
ReplyDeleteDelay and sleep functions can be used by including the "graphics.h" header file.

@Rats These errors occurs due to presence of some non-ASCII characters in the code. These might have crept in accidently while copying it from some where. Check your program for non-ASCII characters by creating dump of the file using the command
ReplyDeleteod -c filename.c (return)
Non-ASCII characters are displayed as escape sequences in the dump file. You can redirect the dump output from the terminal to a file using the command
od -c filename.c>filename (return)
I tried to install libgraph-1.0.2 on ubuntu.the package guile-1.8-dev couldnt get installed.so i tried the command apt-get update.but it doesnt work at all.can you suggest any solution?
ReplyDelete@Ketaki : Did you try the "sudo apt-get update" command or just the "apt-get update". Use sudo command to execute a command as a superuser if you didn't do so.
ReplyDeleteIf it doesn't work, post the messages displayed on the terminal while trying the apt-get update command and during installing the package guile-1.8-dev.
You can also install the packages or update the system using the "Synaptic Package Manager". Just type "guile" in the search box and it will display the list of packages. Mark the required packages for installation and click on apply. After that, follow the on-screen instructions.

$ sudo dpkg --configure -a
After running these commands try running the sudo apt-get update command.
Else you can try finding what's holding the lock by using the command:
sudo lsof | grep /var/lib/dpkg/lock
and kill it by using the "kill" command.
If it doesn't work, post the details here.

Configure the dpkg using the command:
$ sudo dpkg --configure -a
and then install the restricted sources using the command:
$ sudo apt-get install ubuntu-restricted-extras
Try updating the package repositories:
$ sudo apt-get update
If the above steps don't work, try re-configuring the dpkg:
$ sudo dpkg-reconfigure -a
This will take some time. After this try update manager or update the repositories using the "sudo apt-get update" command.
As for kill, it is a command which requires options and parameters as you can see in its man page. It requires the signal number and the process id of the process to be killed. For details, view its man page.

NTVDM allows a 16-bit DOS program to execute on Windows. It is basically a DOS emulator.
DeleteWhat version of Win XP are you using: 32-bit or 64-bit? Try using a emulator (such as dosbox) to run your program. This might help.
You can also try replacing the ntvdm.exe file in system32 directory by the one on the windows CD. Or repair Windows using the Win Xp CD.

You can delete the extracted folder.
ReplyDeleteAll built-in functions in C will work here. Only the compiler is different. If you are asking whether all built-in functions available under Turbo C or Windows will work here, the answer is No. Some built-in functions won't work like clrscr() and some more.
Could you give me alternatives to the following functions?
Deletegetch()
clrscr()
Also, i am getting an error while compiling-
undefined reference to 'initgraph' or any graphics library function.
thanks
Instead of clrscr(), use the system call- system("clear") or system("tput clear") in your program.
Deletegetch() works after you install libgraph. If you want, you can use a function (Source: Google Search):
#include
#include
#include
int getch(void)
{
struct termios oldattr, newattr;
int ch;
tcgetattr( STDIN_FILENO, &oldattr );
newattr = oldattr;
newattr.c_lflag &= ~( ICANON | ECHO );
tcsetattr( STDIN_FILENO, TCSANOW, &newattr );
ch = getchar();
tcsetattr( STDIN_FILENO, TCSANOW, &oldattr );
return ch;
}
Also you can use the "ncurses" library.
Regarding your error "undefined reference to libgraph" while compiling, just make sure you are using the command:
Delete$ gcc pgm.c -lgraph
while you compile you program.
Hope this helps.
The includes in the above comment are:
Deletetermios.h
unistd.h
stdio.h

ReplyDeleteHi Shekhar,

while typing the command ./configure, shows an error : permission denied.. is any solution for this ? plz rply.. thanx in adv...
ReplyDeleteJust check for the permission using the chmod command. You might not have the privilege to run this command on the system.

Check whether SDL is installed on your system or not. If it's installed, try updating it or go for re-installation of the same.
