update:
Adding a single line to the json file shown in the attached image solved the undefined references problem. However, the opensprinkler.h file has “includes” for files not in the source folder as shown in a second attached image. The third attached file shows some of the errors. The local G++ compile doesn’t seem to care but vscode sure does. Note openthingsframework seems to handled in the platformio.ini file build instructions for non-pi versions of the code.
