# Building Source Code


With DevEco Device Tool, you can easily build source code of the Rockchip RK3568 development board, thanks to its productivity-boosting features, such as the compiler toolchain, detection of the build environment dependencies, and one-click installation of the dependencies.

> The build environment of RK3568 is Ubuntu.


1. Click **Project Settings** on the menu bar to access the RK3568 project configuration page.

2. On the **Tool Chain** tab page, DevEco Device Tool automatically checks whether the dependent compiler toolchain is complete.

   - If any tool is indicated as **uninstalled** (![status_uninstall](figures/status_uninstall.png)), click **Download Uninstalled Tools** to install all the required tools, or click **Download** next to a tool to install the specific tool.
   - If some tool types are missing, click **Add Utility** to add them.
   - If **Download** is not available for a missing tool, it is not cataloged in DevEco Device Tool. In this case, you need to download the tool to the local host and click **Import** to import it.
   - If the status of **OpenHarmony Environment Dependency** is abnormal (![status_uninstall](figures/status_uninstall.png), click **Install**.

   Certain tools may require the root access to install. For these tools, enter the user password in the **TERMINAL** window as prompted.

   > - If APT fails to be installed, [change the APT source](https://device.harmonyos.com/en/docs/documentation/guide/faq-toolchain-install-0000001301623822) and try again.

   After the installation is complete, the status of the tools and environment dependencies is displayed as ![status_install](figures/status_install.png).

3. On the **rk3568** tab page, set **build_type**, whose default value is **debug**.

5. Wait until **SUCCESS** is displayed in the **TERMINAL** window, indicating that the build is complete.

   After the building is complete, go to the **out** directory of the project to view the generated files, which are needed for [burning an image](quickstart-ide-3568-burn.md).
