Failed marlin firmware build, library for I2C and more

Trying to change the fan pinout on my board anyway Ive been running into this issue and not sure what else to do. Ive uninstall everything and reinstalled it. deleted platformio folders and all. So I tried to do a clean build from MarlinFw site with 2.0 and had no issues but when I used the (no changes) 1.1.9 firmware from the website I run into this issue again.

Did you find a solution to this? I’m new to Platformio but decided to try it after switching to Visual Sudio Code. I’m attempting to build Marlin 1.1.9 and getting the exact same error. It builds & uploads fine with Arduino IDE.

Hi Michael, just came to the same point.
I fixed it by changing the dependency in platformio.ini to a new version:
and installed “LiquidCrystal_I2C by ejoyneering” in this actual version in the platformio library manager.
Hope this well help :slight_smile:
