# Building Source Code


With DevEco Device Tool, you can easily build source code of the Hi3516DV300 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.

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 **ipcamera_hispark_taurus** tab page, set **build_type**, whose default value is **debug**.

   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-3516-burn.md).
