1# Full SDK Compilation Guide 2 3The full SDK provides a full set of APIs available in OpenHarmony, including system APIs required by system applications. Vendors can leverage this SDK to develop applications. 4 5Since OpenHarmony 3.2 Beta5, the full SDK is not provided with the version. If necessary, you can compile the SDK using the full source code. 6 7## Compiling the Full SDK 8 9**Preparation** 10 111. Register an SSH public key for access to Gitee. 122. Configure the server environment. For details, see [Setting Up the Ubuntu Environment](../../device-dev/quick-start/quickstart-ide-env-ubuntu.md). 13 14**Procedure** 15 161. Download and initialize the manifest repository: **repo init -u https://gitee.com/openharmony/manifest.git -b $manifest_branch --no-repo-verify --repo-url=https://gitee.com/oschina/repo --no-clone-bundle** 17 182. Download source code based on the downloaded manifest repository: **repo sync -c -d --force-sync** 19 203. Perform precompilation: **yes y | apt install libxinerama-dev libxcursor-dev libxrandr-dev libxi-dev && rm -rf prebuilts/clang/ohos/darwin-x86_64/clang-480513 && rm -rf prebuilts/clang/ohos/windows-x86_64/clang-480513 && rm -rf prebuilts/clang/ohos/linux-x86_64/clang-480513 && bash build/prebuilts_download.sh -ndk && apt-get update -qqy && apt-get install doxygen -y --force-yes** 21 224. Perform compilation: **./build.sh --product-name ohos-sdk** 23 24 25If the compilation is successful, export the files in the **out/sdk/packages/ohos-sdk/** directory. 26 27## Replacing the SDK 28 29After the full SDK is compiled, switch to it in DevEco Studio. For details, see [Guide to Switching to Full SDK](full-sdk-switch-guide.md). 30
