How To Use Geany Debugger

Ubuntu 4

Geany is a lightweight, cross-platform Integrated Development Environment (IDE) that supports a wide range of programming languages. One of its powerful features is the built-in debugger. This article will guide you through the process of installing and using the Geany Debugger.

Quick Answer

To use the Geany Debugger, you need to first install the necessary tools such as gcc and gdb, as well as Geany and the Geany plugins. Then, you can configure Geany and set up the build commands. After that, you can set breakpoints in your code and start the debugging process. While there is no clear documentation available, you can refer to the Geany Debugger plugin page for more information and search for tutorials or walkthroughs for practical examples.

Prerequisites

Before we start, ensure that you have gcc and gdb installed on your system. These are the GNU Compiler Collection and the GNU Debugger, respectively. You can install them using the following command:

sudo apt install gcc gdb

Also, make sure you have Geany and the Geany plugins installed. If not, use the following command:

sudo apt install geany geany-plugins

Configuring Geany

After successfully installing the necessary tools, open Geany and navigate to the Plugin Manager by clicking on menu -> Tools -> Plugin Manager. In the list of plugins, find and check the box next to “Debugger”. This will activate the debugger plugin. If Geany was already open, you might need to restart it for the changes to take effect.

Setting Up Build Commands

Next, you need to set up the build commands. Go to menu -> Build -> Build Commands. Here, you need to set the compile and build commands.

The compile command should be:

gcc -g -Wall -c "%f"

This command tells gcc to compile the file ("%f"), include debugging information (-g), and show all warnings (-Wall). The -c flag tells gcc to only compile and not link.

The build command should be:

gcc -g -Wall -o "%e" "%f"

This command tells gcc to compile the file ("%f"), include debugging information (-g), and show all warnings (-Wall). The -o "%e" tells gcc to output the result to an executable file named after the source file.

Setting Breakpoints

Now, open your code file in Geany. You can set breakpoints by clicking next to the line numbers. A red square will appear, indicating the breakpoint.

Starting the Debugging Process

To start debugging, go to menu -> View -> Show Message Window. In the debug tab of the message window, click the target tab. Choose your target (e.g., if your code file is “example.c” and the output is “example”, choose “example” as the target). On the right side of the window, you can start the debugging process.

Unfortunately, there is no clear documentation available for the Geany debugger plugin. However, you can refer to the Geany Debugger plugin page at plugins.geany.org/debugger.html for more information. Additionally, you can try searching for tutorials or walkthroughs on forums or websites like ubuntuforums.org for practical examples and tips on using the Geany debugger.

Please note that the Geany debugger plugin may not be available in all distributions, and in such cases, you may need to compile it from source.
