Intellisense Error for Raspberry Pi Pico boards

[sstaub]

Here a screenshot when using Raspberry Pi Pico boards, get an error which shouldn't happen

I have exactly same error, and have spent hours trying to fix it. Nothing works!!
Arduino IDE works fine.

Maybe it is a general problem 3rd party cores

[StefanKellerAC]

The extension under Windows 10 does not find the paths in the core's subdirectory \Pico-SDK

that may be a problem with \ and / when the extension parses the output, which is e.g.:

"-IC:\\Users\\stefan\\AppData\\Local\\Arduino15\\packages\\rp2040\\hardware\\rp2040\\2.6.4/pico-sdk/src/rp2040/hardware_regs/include/"

they are included by
" \rp2040\hardware\rp2040\2.6.4\lib\platform_inc.txt"
the "standard" includes are found

I proposed a dirty fix there:

Hi all,

I've created a PR for the cocopa library that adds support for GCC Directory Options that is required for arduino-pico to work in this extension.

is now

and my project now works properly.

This library hasn't been updated in a good while, but I hope the patch is merged in and dependency updated. My rp2040 project does not work correctly without it.
