\title Qt for HarmonyOS Prerequisites
\brief Provides instructions to install the tools required to develop Qt
applications for HarmonyOS.
\previouspage Qt for HarmonyOS
\nextpage harmonyos-building.html
\note Qt for HarmonyOS is in technology preview and may change in future
releases.
To develop Qt applications for HarmonyOS, you need to set up your development
host with the OpenHarmony SDK and the related command-line tools.
The same prerequisites apply whether you build \l{Qt for HarmonyOS} from source
or use a pre-built Qt for HarmonyOS to build and deploy your own applications.
\section1 Prerequisites
\list
\li The OpenHarmony SDK command-line tools, which provide the compiler
toolchain, the system libraries, and the \c hvigor build tool used to
assemble a HarmonyOS Ability Package (HAP).
{DevEco Studio}, the official IDE for HarmonyOS, which is convenient for
running and debugging applications on a device or the emulator.
\endlist
\section1 Supported development hosts
The Qt for HarmonyOS toolchain is currently developed and tested on Linux.
\section1 Setting up the SDK
After installing the OpenHarmony SDK command-line tools, point Qt at the SDK so
that the build system can locate the toolchain and system libraries. This is
required both when configuring a Qt for HarmonyOS build from source and when
building applications against a pre-built Qt. You can do this in two ways:
\list
\li Set the \c OHOS_SDK_ROOT environment variable to the SDK root path.
\li Pass the path to \l{Qt for HarmonyOS - Building from Source}{configure}
using the \c -ohos-sdk option.
\endlist
