Unlocking the Power of Linux Debuggers for Optimal Software Development

Debugging is a crucial aspect of software development; it helps identify and resolve errors in code before compilation. In the open-source world of Linux, a variety of debuggers are available, providing solutions for various programming languages and architectures. This guide delves into the standout Linux debuggers programmers should consider to enhance their debugging workflow.

The Power of GNU Debugger (GDB)

The GNU Debugger, commonly known as GDB, is a highly effective tool for modern programmers. It supports popular programming languages, including C, C++, Go, and Rust, while operating on various CPU architectures such as x86 and ARM.

To install GDB, use the following commands:

For Ubuntu/Debian users:

For Fedora/RHEL users:

For Arch-based users:

With a project compiled using GCC and debug symbols, you can begin debugging by running gdb followed by your program’s path. Use s to step through your program’s instructions and r to run it.

Simply type help in GDB to access a comprehensive guide to its features.

Harnessing Data Display Debugger (DDD)

The Data Display Debugger (DDD) provides a graphical interface for GDB, allowing simpler navigation of debugging features. Although the interface may appear minimalistic, the functionality remains robust.
