Unable to resolve dependency

[eldask]

Hello,

I am trying to install the RTClib library which depends on adafruit’s BusIO library. The installation works fine for both RTClib and BusIO, but when I’m trying to build the project, the compiler is unable to find the file Adafruit_I2CDevice.h, even though I can see it under .pio/libdeps/nanoatmega328/Adafruit BusIO/Adafruit_I2CDevice.h

I can also see an entry in c_cpp_properties.json’s includePath that has "c:/libtest/.pio/libdeps/nanoatmega328/Adafruit BusIO"

I have found these two questions which appear to be a similar issues

Dependency Issue? Can't find header file

I’ve been using PIO for over a year, and it’s greatly increased my productivity. But every once in a while I encounter a mysterious problem that is very difficult to resolve. My current problem is that when compiling my program (FireScript.cpp) the compiler complains about not finding a header file (CRC16.h) that’s used by one of my private library modules (SlicBus.cpp). This library module compiles just fine. It includes CRC16.h and the platformio.ini file looks like this: [env:teensy40] platf…

Multiple Library Dependency Issues

I posted this question a few days ago. I’ve made a little bit of progress, but am still very confused and frustrated. I have multiple issues, but for now I’ll stay focused on my issue with the CRC library. Here’s my platformio.ini: [env:teensy40] platform = teensy board = teensy40 framework = arduino lib_ldf_mode = chain+ lib_deps = elapsedMillis robtillaart/CRC @ ^0.3.0 lib_extra_dirs = /Users/keith/Documents/PlatformIO/Projects/EFD_libraries When I delete the .pio folder and do a clean bu…

Unfortunately, the solution on the second question does not appear valid. I am testing on a newly created project with only RTClib as a dependency.

Here is my platformio.ini (version 3.3.1)

[env:nanoatmega328]
platform = atmelavr
board = nanoatmega328
framework = arduino
lib_ldf_mode = chain+
lib_deps = adafruit/RTClib@^2.1.1

And here is my output after deleting .pio, trimmed to the first error

If anybody has any insight, it would be greatly appreciated, thank you!

Update:

updating my platformio.ini to include the dependency yields some progress

[env:nanoatmega328]
platform = atmelavr
board = nanoatmega328
framework = arduino
lib_ldf_mode = chain+
lib_deps = 
	adafruit/RTClib@^2.1.1
	adafruit/Adafruit BusIO@^1.14.5

with this build output

.pio\libdeps\nanoatmega328\Adafruit BusIO/Adafruit_I2CDevice.h:5:10: fatal error: Wire.h: No such file or directory

Cut short for post length. I tried to import Wire.h from my main.cpp because that’s a library I have used in the past, and lo and behold, that made that error go away, but replaced it with a missing SPI.h. I added an include to SPI.h in main.cpp and that fixed it

#include <Arduino.h>
#include <Wire.h>
#include <SPI.h>

void setup() {
}

void loop() {
}

For now I guess the issue is “resolved” but that’s a bandaid and I have absolutely no idea what’s going on, though I am 99.9% sure the issue is on my side. If anybody has any idea what I’m doing wrong, you will make my day!

Thank you
