1# Building Source Code 2 3 4For details about the functions of the OpenHarmony compilation and building module, see [Compilation and Building Guide](../subsystems/subsys-build-all.md). 5 6 7## Prerequisites 8 9- The [required libraries and tools](quickstart-pkg-install-package.md) have been installed. 10 11- The [compilation tools](quickstart-pkg-install-tool.md) have been installed. 12 13- The Hello World program is ready for use. 14 15- The access to the Ubuntu environment is normal. 16 17 18## Procedure 19 20Method 1: using hb for compilation (install [compilation tools](quickstart-pkg-install-tool.md) first) 21 22Go to the root directory of the source code and run the build command. 23 241. Set the build path. 25 26 ``` 27 hb set 28 ``` 29 302. Select the current path. 31 32 ``` 33 . 34 ``` 35 363. Select **ipcamera_hispark_taurus** under **hisilicon** and press **Enter**. 37 >  **NOTE** 38 > 39 > 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](quickstart-appendix-compiledform.md). 40 41 **Figure 1** Hi3516 build settings 42 43  44 454. Start building. 46 >  **NOTE** 47 > - To build a component (for example, **hello**), run the **hb build -T *targetName*** command. 48 > 49 > - To build a product incrementally, run the **hb build** command. 50 > 51 > - To build a product from the scratch, run the **hb build -f** command. 52 > 53 > This example builds a product from the scratch. 54 55 56 ``` 57 hb build -f 58 ``` 59 605. Check the build result. If "build success" is displayed, the building is successful. 61 >  **NOTICE** 62 > 63 > Paths to burning-related files: 64 > 65 > - Build result and log files: **out/hispark_taurus/ipcamera_hispark_taurus** 66 > 67 > - U-Boot file: **device/board/hisilicon/hispark_taurus/uboot/out/boot/u-boot-hi3516dv300.bin** 68 69Method 2: using the **build.sh** script for compilation 70 71For details, see [Building Source Code Using the build.sh Script](quickstart-pkg-common-build.md).
