Build Affinity

Prerequisites

You have logged in to the Kunpeng DevKit.

• /opt is the default installation directory of the tool. The following uses this directory as an example. Replace it with the actual directory.
• On the WebUI, this feature requires uploading the files or compressed package. In the IDE, the tool plugin can scan local projects. If the source code is included in a compressed package, decompress the package and select the decompressed folder.

Procedure

1. On the left pane of the page, choose Affinity Analyzer > Build Affinity, and click to create a task. See Figure 1.
   Figure 1 Build affinity
   

   Table 1 Parameters for build affinity

   Parameter	Description
   Source File Path	Set this parameter using either of the following methods: If you want to use uploaded source code, click the text box and select a source code path from the drop-down list or manually enter a source code path. Click Upload on the right to upload the package or folder. (The package is automatically decompressed during the upload.) NOTE: Only TAR, TAR.BZ, TAR.BZ2, TAR.GZ, TAR.XZ, TBZ, TBZ2, TGZ, TXZ and ZIP packages can be uploaded. Only one package can be uploaded at a time. The source package cannot exceed 1 GB, and the extracted files cannot take up more than half of the remaining drive space. Only one folder can be uploaded at a time. The size of the folder must be less than or equal to half of the remaining drive space. Before manually uploading a software package, check whether the target directory exists. If it does not exist, create such a directory and grant the read, write, and execute permissions to the devkit user.
   Build Tool	Build tool to be used. The options are: make cmake
   Compile Command	Command to be used to compile the source code. The compile command varies according to the build tool configuration file. For details, see Identifying Compile Commands Using the Build Tool Configuration File.
