This article is to share with you what to do if vscode header files cannot be compiled. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

When using VSCODE for C language programming, if the header file declaration function is used and the .c file defines the function, although the corresponding header file has been referenced at the time of compilation, and the VSCODE text editor has not reported an error, it still cannot be compiled.

The error message is as follows:

D:/ComputerHomework/2019_winter/main.c:10: undefined reference to `ReadPathTkFile'

This is because VSCODE is actually a text editor, not an IDE, and it does not automatically link .c files referenced by the project through the header file. To solve this problem, tell the compiler which files to link.

Solution method

Find tasks.json in the .vscode folder under the current path, find the "args" attribute, and after "- g", add "${fileDirname}\\ YourcFileName.c" before "- o", with each set of strings separated by commas. YourcFileName.c is the name of the file in the project to participate in the compilation.

The example is as follows (please refer to the format only. It is normal for specific parameters to be different)

{"tasks": [{"type": "shell", "label": "gcc.exe build active file", "command": "C:\\ mingw64\\ bin\\ gcc.exe", "args": ["- g", "${file}" "${fileDirname}\\ IstkFile.c", "${fileDirname}\\ PrintQuestion.c", "${fileDirname}\\ MarkingSystemLib.c", "${fileDirname}\\ zqyLib.c", "- o", "${fileDirname}\ ${fileBasenameNoExtension} .exe"] "options": {"cwd": "C:\\ mingw64\\ bin"}], "version": "2.0.0"} Thank you for reading!
