Having trouble compiling this

[cems2]

Compiling with Arduino application on OSX. Error is obscure so I'm unsure what might be wrong. I'm trying to compile the Primes.ino example.

Error compiling for board NodeMCU 1.0 (ESP-12E Module).

I wonder if the underlying ESP8266 libraries have changed since I wrote this? I'll do some investigating on my own and let you know.

Can you provide the FQBN from the compilation output?

With the Arduino IDE 1.8.12 and ESP8266 library 2.7.1 I was able to compile the Primes example just fine. I selected NodeMCU version 1.0 as my board and compiled the prime example without errors.

Is your ESP8266 library up-to-date?

I just checked my version numbers and my IDE was up to date but the ESP8266 library was old. I just updated it but have not re-loaded your example today. I suspect that was the problem entirely.

sorry to have bothered you without checking that first.
