General Application Running and Debugging

Prerequisites

• You have logged in to the Kunpeng DevKit.
• The program has been compiled before debugging.
• GDB has been installed on the remote server.
• The C/C++ plugin has been installed. If it is not installed, download the C/C++ plugin installation package (version: 1.6.0 or later) as prompted or from the plugin marketplace.
• In the Resource Manager of VS Code, the folder of the local source program has been opened.
