Building Source Code

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

Method 1: using hb for compilation (install compilation tools first)

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

1. Set the build path.

   hb set
   

2. Select the current path.

   .
   

3. 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.

4. 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
   

5. 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
   

6. 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.

Method 2: using the build.sh script for compilation
