-===== C++ with Qt 5.8 (Cross-Compiling) =====
-__NOTE:__ COMFILE Technology is no longer maintaining the Qt SDK for cross-compiling from Windows to the ComfilePi.  Qt can still be installed onto the ComfilePi from the Raspbian packages using the following procedure:
-==== Buster ====
-<code>
-sudo apt-get update
-sudo apt-get install qt5-default qtbase5-examples qt5-doc qt5-doc-html qtbase5-doc-html
-</code>
-==== Bullseye ====
-<code>
-sudo apt-get update
-sudo apt-get install qtbase5-dev qtbase5-examples qtbase5-doc qtbase5-doc-html
-</code>
-__NOTE:__ COMFILE Technology does not provide technical support for Qt; please [[https://www.qt.io|contact The Qt Company]] for support.
-This procedure makes use of Qt's open source distribution.  Please see Qt's [[https://www.qt.io/licensing/|Licensing]], [[https://www.qt.io/faq/|FAQ]], and [[https://www.qt.io/licensing-comparison/|Licensing Comparison]] for more information about Qt licensing.
-{{ :comfilepi:qt_creator.png |}}
-  - [[.:Install Qt Creator:]] - Qt Creator is the IDE that will be used for developing Qt software.
-  - [[.:Install the ComfilePi SDK:]] - COMFILE Technology has created an SDK that contains all necessary components for compiling and debugging ComfilePi a Qt project with a Windows PC.
-  - [[.:Test an Example Project:|Test a Qt Quick Example Project]] - After Qt Creator and the ComfilePi SDK have been installed, open a sample project, deploy it to the Comfile Pi, and debug it from within Qt Creator
-  - [[.:Create a New Project:|Create a New Qt Quick Project]] - Start from scratch:  Create a new project, deploy it to the Comfile Pi, and debug it from within Qt Creator
-  * [[.:Modbus with Qt:]] - The [[http://doc.qt.io/qt-5/qtmodbus-backends.html|Qt Modbus]] component supports both Modbus RTU and Modbus TCP.  Examples with Qt Widgets and Qt Quick.
-For more information about software development with Qt, see the [[http://doc.qt.io/|Qt documentation]].
-__NOTE__: The build of Qt used in this demonstration uses the EGLFS backend.  Be sure to set the ComfilePi's GPU memory to 256MB or you may experience errors or display anomalies.
-===== Uninstalling Qt5.8 =====
-I you do not wish to use Qt5.8 or you wish to revert to the version of Qt from the original Raspbian distribution, run the following commands to remove Qt5.8:<code>
-sudo rm -rf /opt/Qt5.8
-sudo rm /etc/ld.so.conf.d/01-Qt5.8.conf
-sudo ldconfig
-sudo rm /etc/profile.d/qt5.8-environment.sh
-sudo reboot now
