How to debug C++ Programs using GDB (GNU Debugger) in Linux
Рет қаралды 12,735
Жыл бұрынToday, I will introduce GDB and how you can debug your C++ in Linux. GDB is a GNU Debugger and comes with the installation of gcc/g++ in operating systems such as Linux, MacOS, and Windows. For this tutorial, I will demonstrate under Linux.

Some of you have asked for a C++ debugging tutorial using VS Code extension, I have a video created. please click on this link: kzfaq.info/get/bejne/ospigahoqbWcYmQ.html.

Clear and nice. But I'm wondering if the project is large with unit tests in it. What should I do to debug the unit test?

GDB is usually used for isolating a small area of code that is causing an issue. In general, the unit tests are just a collection of assertions, and so you should have a try/catch block to catch the exceptions. If you have to debug your unit tests, then there are probably other problems. That is just my thoughts.

Usually what is done is, you'll compile a file with its associated unit test file. Then use gdb in a script run/test/ad hoc that small section of code.

I wonder why you dont use the gdb extension for C++ on VSC? I dont know which option may be better, any recomendation?

In this case, GDB is installed under Ubuntu and part of WSL, and so you can use it directly without a VS Code extension. I have not really need to install the VS Code extension since GDB is packaged with GCC compiler.

How can in the same environment and setup by directly applying breakpoints in VSCode and also passing the input arguments in the code

The current video shows the classic way to debug C++ program without VS Code or any GUI/IDE. With VS Code, you can debug C++ program using CodeLLDB as an extension, but unfortunately it's not covered in this video. In addition, you have to setup a configuration in VS Code to build and debug. Once it has been configured, then you can add break points and step through your code. Also, you can use the debug console to review variables, etc. This would be a different video when I have time to create it.
