Installing QT6 and PySide6 on Jetson Orin Nano

I looked around a lot and it took me a lot of work to get this working, so I’m posting it here for others.

I’m using QT Designer for HMI application design. I couldn’t find a version of QT Designer that uses QT5, and my layout designed in QT Designer 6 didn’t work with the pre-built-in QT5 on the Orin Nano. I had to build from source for QT6 on ARM.

I ended up building twice (many hours each time) since I inadvertently missed a necessary plugin the first time. I was not able to install PyQt6 unfortunately, even after much trial and error. I finally got it working with PySide6. Here are the steps:

To build and install the Qt 6.6.1 from the source located at /home/{user}/Downloads/qt-everywhere-src-6.6.1.tar.xz, including the xcb platform plugin, follow these steps:

  1. Extract the Source Code:
    First, you need to extract the downloaded tarball. Open a terminal and run:

    tar -xvf /home/{user}/Downloads/qt-everywhere-src-6.6.1.tar.xz -C /home/{user}/Downloads/

    This will extract the contents into a directory, likely named qt-everywhere-src-6.6.1, in your Downloads folder.

  2. Install Required Dependencies:
    Ensure you have all the required dependencies for building Qt, especially those needed for the xcb plugin:

    sudo apt-get install build-essential libfontconfig1-dev libdbus-1-dev libfreetype6-dev libicu-dev libinput-dev libxkbcommon-dev libsqlite3-dev libssl-dev libpng-dev libjpeg-dev libglib2.0-dev libpulse-dev libasound2-dev libcups2-dev libegl1-mesa-dev libxcb1-dev libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev '^libxcb.*-dev'

  3. Configure the Build:
    Navigate to the extracted Qt source directory and run the configuration script. Ensure you include the -xcb option to include the xcb plugin:

    cd /home/{user}/Downloads/qt-everywhere-src-6.6.1
./configure -platform linux-g++ -xcb -opensource -confirm-license

    Adjust the configuration options according to your needs. The -opensource -confirm-license options are for open source development and to confirm acceptance of Qt’s license.

  4. Build and Install:
    Compile and install Qt:

    make
sudo make install

    This will take a significant amount of time depending on your hardware capabilities.

These steps should help you compile and install Qt 6.6.1 from source with the necessary xcb support.

Hi,
Many thanks for your sharing.
