I tried to update the libraries of my already working project and now the compilation shows the following errors:

For some reason my platformio had loaded an older version of toolchain-xtensa and framework-arduinoespressif8266. I 've updated to 2.100300.220621 (10.3.0) and 3.30102.0 (3.1.2) and now my project compiled successfully.
