Introduction:
GDB stands for "GNU Debugger." It is a powerful and popular debugger tool used primarily for debugging programs written in various programming languages.
The main purpose of GDB is to help developers find and fix bugs in their programs. It allows them to inspect the running state of a program, control its execution, and examine variables and memory.
Installation of GDB
You can easily install GDB on Ubuntu by running the following command on terminal:
1. Updating Package Listing:
sudo apt update
2. Installing "GBD"
sudo apt install gdb
3. Installation Confirmation:
gdb --version
That's it! You have now installed GDB on your Ubuntu system. To use it, simply run it followed by the executable you want to debug, like this:
gdb your_executable
Key Feature Of GDB
Designers can set breakpoints at explicit lines or works in the source code to end the program's execution and assess its state at that point.
GDB gives different commands to step through the program's execution, including stepping line by line, stepping into functions, and stepping out of functions.
It allows developers to obtain a backtrace of the program's call stack by identify the sequence of function calls leading to an issue.
Developers can set breakpoints that trigger just when certain conditions are met, allowing for more fine-grained debugging.
GDB helps developers to examine the values of variables and data stored in memory during program execution.
GDB can be used to analyses core dumps generated when a program crashes, aiding in post-mortem debugging.
GDB package Information:
Conclusion: GDB is a powerful tool used for debugging, and you should have a good understanding of debugging concepts to use it effectively.
