hi

i tried my hand on a graphics program in c++.But when i compile the program, it says header files like graphics.h, conio.h etc not found.

How do i solve this problem?Is graphics used only for Turbo c++ compiler.
What all shud i know b'fore starting off with c++ programming in Linux??

I have Ubuntu (Hoary)....

g++ 3.3
libstdc++5
libstdc++5-3.3 - dgb and dev
gcc 3.3
libgcc


Please Help!!

conio.h is a DOS specific header, and graphics.h is a TC++ specific header. Graphics programming itself is not limited to TC++, though. TC++ itself is an antiquated compiler that pre-dates the latest ANSI standards, and only produces DOS binaries. I'm always surprised when I find people are still using it, actually. There are so many better compilers available for free in both the Linux and Windows worlds.

A lot of graphics programming today is done in the context of a GUI system, such as Windows and X in the Linux world. You'll probably want to take a look at some windowing API. A good one to start with might be SDL, as I believe that has 2d graphics routines similar to what you would find in the old DOS graphics of TC++. I believe SDL also has a mode that allows for graphics outside of a GUI environment, though I've never actually messed with that aspect of it much. SDL is also cross-platform, meaning there are libraries for it in Windows, Linux, etc.

deiussum is absolutely correct on all counts:

1. "conio.h" and "graphics.h" are old Turbo C/DOS headers you aren't likely to see on any current platform: Linux or Windows.

2. SDL might be a good Linux alternative to the old BGI graphics libraries.

3. You might also wish to explore Qt or GTK+ as "standard", cross-platform (Windows *and* Linux) libraries for graphics (and GUIs). My preference is GTK+ (and I use the raw GTK+ API from my C++ programs, much as you used to call the C-language BGI library functions from your Turbo C++ programs).

thanx guys

for clarifying some of my doubts...
But what if I wish to draw just a plane circle,line or polygon and other shapes.Well all this is crap nowadays but my Graphics Course needs it.

Can i draw these thru GTK+ or SDL?
Well i don't know GTK+ or SDL programming.Are there any good sources from where i can learn these??

Please Help!!

Yes, SDL and GTK+ (and many, many others) are *precisely* for drawing plain circles, lines, polygons, etc.

SDL is oriented more toward games: I haven't tried it; I'm not directly familiar with it. You can learn more here:

http://www.libsdl.org/

GTK+ is oriented more toward GUIs. It started out as the base library for "The Gimp" (an extremely popular Open Source graphics program), but it's become much more than that. I have nothing but high praise for GTK+. It's advantages include:

1. It's very easy to write a "hello world" (and only slightly more difficult
to write a "hello world" to a drawing area that lets you draw circles and polygons...)

2. It's cross-platform

3. It supports the gamut of things you'd want to do: user interface, raster imaging, vector drawing, good integration with the underlying windowing subsystem, etc etc:

thanx dude

U have been great help.....
In which languages can i do GTK+ programming??

Does is it significantly change the way i program??
