cannot open source file intellisense error for file that is never opened #870
Description
It would be nice if the intellisense parse did not complain about not being able to open include files that the compiler never accesses anyway. There are some issues posted that sound similar, but were due to problems with the includePath entry in c_cpp_properities.json. This is not. The referenced file does not exist at all, and does not need to exist for the current environment.
#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (/home/phil/development/wcrs/repos/nRF2401-Joy2/nRF2401-Joy2.ino).
cannot open source file "utility/includes.h" (dependency of "RF24.h")However, in RF24.h is…
#if defined (RF24_LINUX) || defined (LITTLEWIRE)
#include "utility/includes.h"
#elif defined SOFTSPI
#include <DigitalIO.h>
#endifand the current environment does not define either RF24_LINUX or LITTLEWIRE.
The parser is obviously tracing the nested includes. Can't it track the defines as well? Probably not near as easy as it sounds.
A common case for this, is the WProgram.h include file that was used prior to the Arduino IDE version 1.0. There are (or at least used to be) libraries that have if/else defs to include either that or the replacement Arduino.h, depending on the environment version. Which is ALWAYS going to generate bogus cannot open messages. Only one of the files in the #if #else are going to exist in a single environment.
