Qt for HarmonyOS Prerequisites

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 Qt for HarmonyOS from source or use a pre-built Qt for HarmonyOS to build and deploy your own applications.

Prerequisites

• The OpenHarmony SDK command-line tools, which provide the compiler toolchain, the system libraries, and the hvigor build tool used to assemble a HarmonyOS Ability Package (HAP).
• Optionally, DevEco Studio, the official IDE for HarmonyOS, which is convenient for running and debugging applications on a device or the emulator.

Supported development hosts

The Qt for HarmonyOS toolchain is currently developed and tested on Linux.

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:

• Set the OHOS_SDK_ROOT environment variable to the SDK root path.
• Pass the path to configure using the -ohos-sdk option.
