#include <Arduino.h> path broken (I think)

degs · December 19, 2023, 6:05pm

Here are my 2 problems:
#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (C:\Users\derek\Documents\PlatformIO\Projects\ArduinoUno R3 Detect I2C Address\src\main.cpp).

cannot open source file “avr/pgmspace.h” (dependency of “Arduino.h”)

Here is the output from Platformio: Build

What have I broken that generates the Problems??
I uninstalled Platformio and deleted the ,platformio folder and did a clean build. everything looks OK but I get the issue of the 2 above Problems???

Please advise/ help…much appreciated as always

Does the file C:\Users\derek\.platformio\packages\toolchain-atmelavr\avr\include\avr\pgmspace.h exist?
What other VSCode extensions besides PlatformIO do you have installed?
What’s the content of the .vscode/c_cpp_properties.json?

degs · December 19, 2023, 8:41pm

pgmspace.h exists
VSCode extensions:
Arduino for VSCode
c/c++ Intellisense
c/c++ Extension Pack
c/c++ Runner
c/c++ Themes
c Make
c Make Tools
Code LLB
Pylance
Python
Serial Monitor

I could not find .vscode/c_cpp_properties.json
The only .json file there is argv (Type JSON source file)

If it helps Platformio hasn’t been the same after I followed the Microsoft tutorial to make my first C++ file in their examples tutorial.

I’ve also got this in the OUTPUT section of the terminal window.
[12/19/2023, 8:59:09 PM] Unable to resolve configuration with compilerPath “C:/msys64/ucrt64/bin/gcc.exe”. Using “cl.exe” instead.

Yikes, then PlatformIO is unable to claim the C++ intellisense for itself. And looking in your extension lists, there are lots of conflicting extensions.

Deactivate or uninstall the “Arduino for VSCode”, “C/C++ Runner”, and “CMake” extensions. Then use Ctrl+Shift+P → Rebuild Intellisense Index to hopefully generate the right .vscode/c_cpp_properties.json.

Hi Max, thanks for your latest reply and help so far…but the plot thickens, and I think the more information I provide as a ‘Newbie’ (before I execute what you advise in uninstalling the extensions) will allow the more skilled and learned of you to analyse events more precisely.
Last night I got things working (don’t ask how) though I think it isn’t fixed properly yet, and realised the problem before was because the Platformio CLI wasn’t being invoked (and additionally Intellisense wasn’t working) as I had noticed the full suite of icons were not being displayed at the bottom of the VSCode screen next to the Platformio home icon.
I now see at the rhs of the screen a Platformio CLI notification.
However ALL this happened because (in my opinion) last week I simply wanted to use VSCode to learn and improve my knowledge of how to use and study C++ under the VSCode IDE.
I followed ‘Get started with VS Code’ under the Walkthroughs on the VSCode Home page, and simply followed the tutorial to write, compile execute the ‘Hello World’ example. In that tutorial is where I added the associated C/C++ extensions.
My limited knowledge led me to believe that I could simply use VSCode to learn C/C++ under this IDE and then simply switch to the Platformio extension when I wanted to…Is this the problem???
My Folder Paths now look like this:
Users/Derek/Documents/Platformio/Projects/.vscode
c_cpp_properties JSON Source File
launch JSON Source File
settings JSON Source File

Users/Derek/Documents/C++/.vscode
c_cpp_properties JSON Source File
launch JSON Source File
settings JSON Source File

My limited but getting better knowledge, reasons that using VSCode in the way I did created the problem I experienced?
I have also now this message in the Terminal when I start VSCode

PS C:\Users\derek\Documents\PlatformIO\Projects\Arduino 7SegLED_Temperature> pio --help

More than happy to help or be corrected on anything so long as I’m learning/improving my understanding.
