If you're encountering issues with graphics.h, conio.h, and dos.h not working in GCC on your Ubuntu system, you're not alone. These header files are often associated with graphics and console-based programming in C and C++, but their usage can be platform-dependent. Ubuntu, being a Linux distribution, has some differences from the DOS and Windows environments where these headers are more commonly used. In this guide, we'll explore common challenges and provide solutions for making these headers work on Ubuntu with GCC.

Graphics.h Issues:

Missing Graphics Library:
The graphics.h header is closely tied to the BGI (Borland Graphics Interface) library, which is not available by default on Linux systems. To resolve this, you can install the necessary library using the following commands:

Linking Graphics Library:
After installing the library, you need to link it explicitly while compiling your program. Use the -lgraph option with GCC:

Conio.h Issues:

Non-Standard Header:
Conio.h is a non-standard header that is primarily used in DOS and Windows environments. Unfortunately, it is not available in the standard GCC on Linux. You might need to consider alternative approaches for console-based input/output operations.

Curses Library as an Alternative:
For console-based programming on Linux, the curses library is a popular choice. You can install it using:

And then compile your program with the -lncurses option:

Dos.h Issues:

DOS-Specific Features:
Dos.h contains functions and features specific to DOS environments, making it incompatible with Linux. Consider refactoring your code to use Linux-compatible libraries and functions.

Time Functions Replacement:
If your code uses dos.h for time-related functions, you can replace them with standard C library functions like time.h on Linux.

By addressing these issues, you can make your C and C++ programs compatible with Ubuntu's GCC environment. Keep in mind that Ubuntu encourages the use of standard and cross-platform libraries, so exploring Linux-friendly alternatives is often a good practice.
