If not, substitute the actual compiler command name. Here, I have assumed you are using gcc as your compiler. Then, run these commands in a shell: $ touch empty.c $ gcc -v -E -dD empty.c The output will show you which compiler VSCode found and what it detected as its built-in include path and preprocessor defines. Next, in Command Palette, run 'C/C++: Log Diagnostics'. (If you don't know what that means, skip it at first.) You may also need to adjust the Compiler arguments, particularly if the compiler is capable of generating code for multiple targets, for example, both 32-bit and 64-bit code. Not at first! Before changing the include path, if you haven't already, first set the 'Compiler path' to point at your C/C++ compiler, and set 'IntelliSense mode' to match the compiler as closely as possible. So should I fiddle with includePath when VSCode tells me to?

That allows VSCode to see definitions of symbols defined in those files. The includePath tells VSCode (specifically the IntelliSense component of the C/C++ extension) where to look when resolving #include 'filename' directives. Then look for the 'Include path' setting. To do that, open the Command Palette (Ctrl+Shift+P) and run 'C/C++: Edit Configurations (UI)'. You can edit c_cpp_settings.json directly, but it is usually easier to use the 'C/C++ Configurations GUI'. vscode folder of the main folder you have opened in VSCode using File → Open Folder.

The includePath is an attribute in c_cpp_settings.json, which is in the. Although the question mentions Arduino, the following suggestions apply basically any time VSCode tells you to 'update your includePath'.
