In the open source software VSCODE, extension plug-ins are generally installed to improve work efficiency. Especially C/C, generally these are necessary: ​​

1, C/C

2, C Intellisense

Among them: C Intellisense The plug-in requires the support of GNU Global, which is a program similar to CTag that can create Tags required to implement indexing and auto-completion functions. Therefore, the function of finding references cannot be realized before GUN GLOBAL is installed.

Solution:

1. Download the Windows version of GNU Global. After downloading and decompressing, configure the Win system PATH to the /bin directory of the GNU Global directory. This directory contains gtag.exe and other binary files.

Or download the Win32 program from the GTAGS official website, unzip it, place it in a suitable location, add the /bin folder under its directory to the system path, and restart the computer.

2. Open the project with vscode, ctrl shift c to open CMD, enter gtags, and three gtag files will be generated in the project.

3. Key points: The project path cannot contain Chinese characters; it cannot contain spaces; when entering gtags, it must be based on the project file name.

The reference reference is now in effect.
