PlatfomIO cannot find a cpp file

Hello,
I think there is a problem with my paths. I am including HardwareSerial.h for an arduino project, but platformIO doesn’t manage to build because it cannot find the corresponding cpp files. It looks in the following directory:

`

/home/antonio/OpenSourceCelluloid/software/platformIO/PCB-NANO/home/antonio/.platformio/packages/framework-arduinoavr/cores/arduino/HardwareSerial0.cpp

`

PCB-NANO is the directory where my project is, but for some reason it goes back to home (/home/antonio) and starts looking for the packages. How can I fix this?

What’s your platformio.ini and code?

This is my .ini:

PlatformIO Project Configuration File

Build options: build flags, source filter
Upload options: custom upload port, speed and extra flags
Library options: dependencies, extra library storages
Advanced options: extra scripting

Please visit documentation for the other options and examples

[env:nanoatmega328]
platform = atmelavr
board = nanoatmega328
framework = arduino
monitor_speed = 115200

Do you need to see the header, the .cpp or the main.cpp? It could get too long if I post all three.

Could you upload the (cleaned) project to github or zip on like GoogleDrive?

Thank you very much for your help, here is the github link:

I can build the firmware fine (though I have to remove 3 libraries in https://github.com/acastles91/pcb-nano/tree/master/lib to which you forgot to include as a submodule / file and do it via lib_deps):

In a PIO terminal, what is the output of pio --version?

Also please execute

pio run -t clean
pio run -v > compile.log 2>&1

and upload the resulting compile.log to pastebin.com and post the link here.

Thank you max, and sorry for the inconvenience with submodules, I still don’t know how to use them since I’m still very new with git and programming.

My pio --version is:
PlatformIO, version 4.1.0

The .log is here:

https://pastebin.com/vQfG8EcR

The path looks OK and they are not concatenated.

/home/antonio/.platformio/packages/framework-arduinoavr/cores/arduino/HardwareSerial0.cpp: In function 'void __vector_18()':
/home/antonio/.platformio/packages/framework-arduinoavr/cores/arduino/HardwareSerial0.cpp:49:5: error: 'Serial' was not declared in this scope
     Serial._rx_complete_irq();
     ^
/home/antonio/.platformio/packages/framework-arduinoavr/cores/arduino/HardwareSerial0.cpp: In function 'void __vector_19()':
/home/antonio/.platformio/packages/framework-arduinoavr/cores/arduino/HardwareSerial0.cpp:64:3: error: 'Serial' was not declared in this scope
   Serial._tx_udr_empty_irq();
   ^

Still this error in the framework makes no sense. The definition of Serial is in HardwareSerial.h which is included.

Please remove the folder /home/antonio/.platformio/packages/framework-arduinoavr completely, then retry compilation.

It’s compiling now, thanks! No idea why it was looking for the files somewhere else.
