Linux framebuffer qt

Qt is a popular cross-platform framework for developing graphical user interfaces (GUI) and applications. It provides support for Linux framebuffer, which allows you to create GUI applications that can run directly on the Linux framebuffer without the need for an X server.

To use Qt with Linux framebuffer, you can follow these general steps:

1. Install the required dependencies: Make sure you have the necessary libraries and development packages installed on your Linux system. This may include framebuffer-related libraries like `libdrm` and `libgbm`.

2. Configure Qt with framebuffer support: When building Qt from source, you can enable framebuffer support by passing the `-qt-libinput` flag to the `configure` script. For example:

   ./configure -qt-libinput

3. Build your Qt application: Once Qt is configured with framebuffer support, you can build your application using the `qmake` and `make` commands as usual. Make sure to set the appropriate target platform, such as `linuxfb`.

4. Run your Qt application on the Linux framebuffer: After building your application, you can run it directly on the Linux framebuffer by setting the appropriate environment variables. For example:

   export QT_QPA_PLATFORM=linuxfb
   export QT_QPA_FB_TTY=/dev/fb0
   ./your_application

By following these steps, you should be able to develop and run Qt applications using the Linux framebuffer as the target platform. Keep in mind that framebuffer support may vary depending on your specific Linux distribution and hardware setup.
