QGroundControl builds are supported for OSX, Linux, Windows, iOS and Android. QGroundControl uses [Qt](http://www.qt.io) as its cross-platform support library and uses [QtCreator](http://doc.qt.io/qtcreator/index.html) as its default build environment.

###### Install QT
You need to install Qt as described below instead of using pre-built packages from say, a Linux distribution, because QGroundControl needs access to private Qt headers.

* Download the [Qt installer](http://www.qt.io/download-open-source)
* Make sure to install Qt version **5.9.2**. You will also need to install the Qt Speech package.
* Make sure to install Qt version **5.9.3**. You will also need to install the Qt Speech package.
* Ubuntu: Set the downloaded file to executable using:`chmod +x`. Install to default location for use with ./qgroundcontrol-start.sh. If you install Qt to a non-default location you will need to modify qgroundcontrol-start.sh in order to run downloaded builds.
* Windows: Make sure to install VS 2015 32 bit package.
