Building for OpenHarmony

Support for OpenHarmony is currently in-progress and these instructions might change from time to time and might also be incomplete.

Get the OpenHarmony tools

Building for OpenHarmony requires the following:

The OpenHarmony SDK. This is sufficient to compile servo as a shared library for OpenHarmony.
The hvigorw build tool to compile apps into an app bundle and sign it.

Setting up the OpenHarmony SDK

The OpenHarmony SDK is required to compile applications for OpenHarmony.

DevEco Studio is an IDE for developing applications for HarmonyOS NEXT and OpenHarmony. It supports Windows and MacOS. You can manage installed OpenHarmony SDKs by clicking File->Settings and selecting "OpenHarmony SDK". After setting a suitable installation path, you can select the components you want to install for each available API version. DevEco Studio will automatically download and install the components for you.

Manual installation of the OpenHarmony SDK (e.g. on Linux)

Before rushing and downloading the OH SDK from gitee as described here, please note that you will also need hvigor to compile applications. hvigor is currently recommended to be downloaded via the HarmonyOS NEXT commandline tools package, which also contains a copy of the OpenHarmony SDK.

Go to the OpenHarmony release notes and select the version you want to compile for. Scroll down to the section "Acquiring Source Code from Mirrors" and click the download link for the version of "Public SDK package for the standard system" matching your host system. Extract the archive to a suitable location. Then switch into the SDK folder with cd <sdk_folder>/<your_operating_system> and unzip the zip files of the individual components. Preferably use the unzip command on the command-line, or manually ensure that the unzipped bundles are called e.g. native and not native-linux-x64-5.x.y.z. On windows, it is recommended to use 7zip to unzip the archives, since the windows explorer unzip tool is extremely slow.

Manual installation of the HarmonyOS NEXT commandline tools

The HarmonyOS NEXT commandline tools contain the OpenHarmony SDK and the following additional tools:

codelinter (linter)
hstack (crash dump stack analysis tool)
hvigor / hvigorw (build tool)
ohpm (package manager)

Currently, the commandline tools package is not publicly available and requires a chinese Huawei account to download.

Manual installation of hvigor without the commandline tools

This section is not fully tested and may change based on user feedback. It's recommended to install the commandline-tools bundle. If you decide to install manually, you need to take care to install the hvigor version matching the requirements of your project.

hvigor (not the wrapper hvigorw) is also available via npm.

Install the same nodejs version as the commandline-tools ship. For HarmonyOS NEXT Node 18 is shipped.

Edit your .npmrc to contain the following line:

@ohos:registry=https://repo.harmonyos.com/npm/

Install hvigor and the hvigor-ohos-plugin

npm install @ohos/hvigor
npm install @ohos/hvigor-ohos-plugin

Set the following environment variables

# Note: The openharmony sdk is under ${DEVECO_SDK_HOME}/HarmonyOS-NEXT-${HOS_VERSION}/openharmony
# Presumably you would need to replicate this directory structure
export DEVECO_SDK_HOME=/path/to/commandline-tools/sdk
export NODE_HOME=/path/to/node
export PATH=${NODE_HOME}/bin:$PATH

Now you should be able to run hvigor.js in your OpenHarmony project to build a hap bundle:
```
/path/to/hvigor.js assembleHap
```

Configuring hdc on Linux

hdc is the equivalent to adb for OpenHarmony devices. You can find it in the toolchains directory of your SDK. For convenience purposes, you might want to add toolchains to your PATH. Among others, hdc can be used to open a shell or send/receive files from a device hdc needs to connect to a physical device via usb, which requires the user has permissions to access the device.

It's recommended to add a udev rule to allow hdc to access the corresponding device without needing to run hdc as root. This stackoverflow answer also applies to hdc. Run lsusb and check the vendor id of your device, and then create the corresponding udev rule. Please note that your user should be a member of the group you specify with GROUP="xxx". Depending on your Linux distributions you may want to use a different group.

To check if hdc is now working, you can run hdc list targets and it should show your device serial number. If it doesn't work, try rebooting.

Please note, that your phone needs to be in "Developer mode" with USB debugging enabled. The process here is exactly the same as one android:

Tap the build number multiple times to enable developer mode.
Then navigate to the developer options and enable USB debugging.
When you connect your device for the first time, confirm the pop-up asking you if you want to trust the computer you are connecting to.

Installing and running on-device
