Configuration method for using Qt Creator for embedded development on Linux systems

Introduction:
The development of embedded systems requires a powerful integrated development environment (IDE) to facilitate writing, debugging and Deploy the application. Qt Creator is a very popular cross-platform IDE that provides a wealth of functions and tools to make embedded development more efficient. This article will introduce the configuration method of using Qt Creator for embedded development on Linux systems and provide some code examples.

1. Install Qt Creator
Before we start, we need to install Qt Creator first. You can download the latest QtCreator version from the Qt official website (https://www.qt.io). Select the binary package suitable for Linux systems and install it according to the official instructions. After the installation is complete, Qt Creator can be found in the application menu.

2. Set the Qt version

1. After opening Qt Creator, click "Tools" - "Options" - "Build and Run" - "Kits".
2. Click the "Add" button and select the Qt version you are using. If you have installed the Qt development framework, you can click the "Detect" button to automatically detect the installed Qt version.
3. Select the Qt version suitable for your embedded platform, and set up the relevant build tools and debugger.

3. Create a new project

1. Select "New File or Project" in the "File" menu, or use the shortcut key Ctrl N.
2. Select "Other Projects" - "Empty Project" in the "Project" tab.
3. Fill in the project name and save path, and click "Next".
4. Select the Qt version set previously in the "Build Configuration" tab and click "Finish".

4. Configure build options

1. In the project navigation pane on the left, right-click the project name and select "Properties".
2. In the "Build Steps" tab, make sure the "qmake" option is checked. This will automatically generate the Makefile.
3. In the "Build Steps" tab, click "Add Build Step" and select "Custom Build Step".

4. In the "Step" field, enter the following command line:

    make -j$(nproc)

   This will use all CPU cores for parallel compilation, speeding up compilation.

5. Select the relevant build configuration and build directory, and click "OK".

5. Add source code files

1. In the project navigation pane on the left, right-click the project name and select "Add New File".
2. Select "C Source File" or "C Source File" in the "File" tab and click "Next".
3. Fill in the file name and save path, and click "Finish".
4. Write the code for the embedded application in the editor pane.

6. Configure the debugger

1. Click "Tools" - "Options" - "Debugging" - "General".
2. Select the debugger suitable for your embedded platform and set the relevant debugger path and parameters.

7. Build and run the project

1. Click the green triangle button on the toolbar or use the shortcut key Ctrl R to build and run the project.
2. If everything is set up correctly, the application will be compiled and run on the embedded device.

Conclusion:
Through the above steps, we can successfully configure Qt Creator on the Linux system for embedded development. Qt Creator provides a wealth of functions and tools to improve development efficiency from creating projects to building, debugging and deploying applications. At the same time, this article also provides some code examples to help readers better understand and use Qt Creator for embedded development.

The above is the configuration method for using Qt Creator for embedded development on Linux systems. I hope this article can provide help and guidance to developers who are doing embedded development.
