this is with a fresh install of platformio. simple arduino/uno project, single file blink.cpp:

    #include <Arduino.h>
    #include <utility/Adafruit_GFX.h>

it looks like the include direectories aren’t getting set up correctly.

Sorry, never worked with GFX libraries, tried to compile graphicstest.pde which worked fine.
Can you provide a simple example?

3

That’s it, just those two lines above in a .cpp file.

4

Arduino needs a setup an loop function.

5

sure, add those. it doesn’t help. the error still persists. did you actually try to build it?

Sorry, I don’t understand what you trying to do.
Are you familiar with c-programming?
