ESP32: Adafruit_GPS.h collides with SD.h

PlatformIO IDE
1

When including the Adafruit GPS library and Espressif’s SD library, I get a list of errors. Somehow both libraries collide, but I currently don’t see why.

platformio.ini:

[env:esp32dev]
platform = espressif32
board = esp32dev

framework = arduino

lib_deps =
        adafruit/Adafruit GPS Library @ 1.5.2
lib_ldf_mode = deep

main.cpp:

#include <Arduino.h>
#include <Adafruit_GPS.h>
#include <SD.h>
void setup() {
}
void loop() {
}

Errors:

When I disable this option and remove the predownloaded SD lib in .pio\libdeps, PIO finds the correct library. “Verbose build all” gives

which is correct.

Seems like the library dependency finder didn’t get the correct dependencies or respected the architcture constraints (the wrong SD library is marked with atmelavr as platform after all.

If you don’t need lib_ldf_mode, remove it. Otherwise I suggest to copy C:\Users\<user>\.platformio\packages\framework-arduinoespressif32\libraries\SD to the lib/ folder, remove the .pio\ folder of the project and recompile, in hopes that it will take that local library for the SD dependency.
