[.pio/build/esp32dev/firmware.elf] Implicit dependency `/Users/user/.platformio/platforms/espressif32/builder/=' not found, needed by target `.pio/build/esp32dev/firmware.elf'

Good Afternoon

Trying to build my code, there appears a final failure message like this:

*** [.pio/build/esp32dev/firmware.elf] Implicit dependency `/Users/cirobruno/.platformio/platforms/espressif32/builder/=' not found, needed by target `.pio/build/esp32dev/firmware.elf'.

Please, would any one suggest where to start from?

Thank you.

Problem found!

I’ve found a post with this solution. But unfortunately I lost it and I won’t be able to give credits to the author. I’d like to share it here for the record. Someone might face the same problem.

The matter regards the space characters before and/or after the equal (“=”) sign in platformio.ini file, among the build_flags options.

Example of wrong way to write your statements:

	-DTFT_WIDTH = 320

And the right way:


Thank you, whomever has tried to think a solution for my problem.
Best regards,
