## Using the build.sh Script to Build Source Code


1. Go to the root directory of the source code and run the build command.
   
   ```
   ./build.sh --product-name name --ccache
   ```

   > ![icon-note.gif](public_sys-resources/icon-note.gif) **NOTE**
   > _name_ indicates the product name, for example, **hispark_taurus_standard** and **rk3568**.

2. Check the build result. After the build is complete, the following information is displayed in the log:
   
   ```
   post_process
   =====build name successful.
   ```

     Files generated during the build are stored in the **out/{device_name}/** directory, and the generated image is stored in the **out/{device_name}/packages/phone/images/** directory.
