Building Source Code

You can build source code with hb or the build.sh script. This topic describes how to build source code with hb. For details about how to use the build.sh script, see Building Source Code Using the build.sh Script.

For details about the functions of the OpenHarmony compilation and building module, see Compilation and Building Guide.

Prerequisites

The required libraries and tools have been installed.
The compilation tools have been installed.
The Hello World program is ready for use.
The access to the Ubuntu environment is normal.

Procedure

Go to the root directory of the source code in the Ubuntu environment and perform the following steps:

Set the build path.

   hb set

Select the current path.

Select rk3568 under hihope and press Enter. > NOTE > > When adapting the development board to a specific use case, select an appropriate build form factor, that is, product settings. For details, see Build Form Factors.

If you are building the source code into a 32-bit system, skip this step.

If you are building the source code into a 64-bit system, run the following command:

   hb build --target-cpu arm64

Start building. > NOTE > - To build a component (for example, hello), run the hb build -T *targetName* command. > > - To build a product incrementally, run the hb build command. > > - To build a product from the scratch, run the hb build -f command. > > This example builds a product from the scratch.

   hb build -f

Check the build result. If “rk3568 build success” is displayed, the building is successful. > NOTICE > > The build result and log files are stored in out/rk3568.
