Configuration tips for using CLion for embedded C/C development on Linux systems

With the continuous development of embedded systems, C/C is still the main language for developing embedded applications. During the development process, a suitable integrated development environment (IDE) is crucial to improving development efficiency. CLion is a cross-platform C/C development environment developed by JetBrains. It provides powerful functions and a friendly user interface, making embedded development easier and more efficient.

This article will introduce how to configure CLion on a Linux system for embedded C/C development, and provide some practical tips and code examples.

1. Installing CLion

First, we need to download the CLion installation package from the JetBrains official website. According to your Linux distribution, select the corresponding installation package to download. Once the installation is complete, open CLion and enter the initial setup.

2. Configuring the compiler and build system

In the initial setup interface, select the "Toolchains" option and click the " " icon to add a new compiler. Choose GCC or Clang as the compiler according to your needs. Then, click "OK" to save the settings.

Next, select the "Build, Execution, Deployment" option, click the "Toolchains" tab, select the compiler just added on the right, and specify the path for it. Click "OK" to save the settings.

3. Create project

In CLion, you can create a project in the following two ways:

Method 1: Import from existing source code
If you already have the source code of an embedded project, you can select "Open Project" and import the source code directory. CLion will automatically identify the project's CMakeLists.txt file and configure it.

Method 2: Create a new project from a template
If there is no ready-made source code, you can select "New Project" to create a new project. Select the embedded tool chain in the project settings, and CLion will automatically generate a CMakeLists.txt file suitable for embedded development for you.

4. Configuring the debugger

Select "Edit Configurations" under the "Run" menu and click the " " icon to add a new configuration. Select "C Remote Debug" as the configuration type and make the following settings:

• Name: The name of the configuration
• Executable: Select the compiled executable file path
• GDB/CDB Debugger: Select the appropriate debugger (for example, GDB for Linux)
• Connection: Set the host and port (for example, localhost:1234)

Click "OK" Save configuration.

5. Running and debugging

In CLion, you can run and debug embedded applications in the following two ways:

Method 1: Run locally
Click the "Run" button (green triangle), CLion will connect to the target device via SSH and then run the application on it.

Method 2: Remote Run
Click "Attach to Local Process" under the "Run" menu and select the previously configured remote debugging configuration. CLion will connect to the debugger of the target device through the GDB server and perform remote debugging.

6. Other common tips

• Auto-completion: CLion provides a powerful code auto-completion function, which can quickly complete the code through shortcut keys (such as Ctrl Space) .
• Code navigation: CLion supports functions such as quickly jumping to definitions and viewing function call levels. Code navigation can be easily performed through shortcut keys (such as Ctrl and left mouse button).
• Code Refactoring: CLion provides a wealth of code refactoring functions, including renaming, extracting functions, extracting variables, etc. Code refactoring can be easily performed through shortcut keys (such as Shift F6).
• Version control: CLion provides integrated support for common version control systems (such as Git), making it easy to submit and pull code.

To sum up, CLion is a powerful and easy-to-use embedded C/C development environment, which is very convenient for embedded development on Linux systems. By correctly configuring and understanding some skills of CLion, you can improve development efficiency and speed up the project development process.

Code example:

include

int main() {

printf("Hello, CLion for Embedded Development!

");

return 0;

}

The above is a simple C language code example for outputting a message on the console. Through CLion's editor, we can easily edit and run such embedded applications, and debug and test.
