Visual debugging front-end software installation, testing and basic use
Visual debugging of front-end software testing based on gcc and gdb in the back-end
1. Visual front-end Kdbg
Kdbg installation
Installation process reference blog

Based on the above blog, there are several points to note:
Note 1: Pay attention to the directory where the command is entered during the installation of kdbg. After downloading the kdbg, the kdbg file will be generated in the home directory, and you must cd in to execute the installation command cmake.
The problem that may occur after cmake is as follows:
After that, the problem is handled according to the reference blog.
Note 2: After downloading the QT installation package, the installation package will be in the downloads folder. At this time, double-clicking the file cannot be installed. First, enter the chmod +x qt-opensource-linux-x64-5.9.0.runcommand in the terminal cd into the downloads file to obtain the installation permission, and then double-click the file to install QT.
Note 3: When installing the kf5 library, you must return to the home directory (command: cd ~) before entering the series of commands and enter the installation, otherwise cmake will not succeed.
After cmake is successful, basically the last two commands can be executed smoothly.
After the installation is successful, directly call the kdbg command to use kdbg normally.
Kdbg visual code debugging test
That is, you can set breakpoints in the graphical interface, enter test data, and track and debug the code
2. Visual front-end VScode
VScode installation
Directly search for Visual Studio Code in the Ubuntu software store and click to download
VScode visual code debugging test
1. Download the plug-in that supports c/c++ at the prompt, or search for plug-in download by ctrl+p.
2. Use VScode to visually
debug the program 1. Add a debugging program:
2. Select a file for debugging (the fifth icon is where the debugging function is located)
3. After selecting the pop-up debugging method (gdb), select gcc to compile, and the system will automatically generate a suffix After the file is json, click the green arrow to complete the debugging, and display the result and prompt information on the terminal.
