build error when using incorrect version of ESP-IDF

[FreemanGBG]

I was just getting started on Moddable Two and doing some basic examples. Here is what I currently face:

C:\Projects\moddable\examples\helloworld>mcconfig -d -m -p esp32/moddable_two
C:\Projects\moddable\build\tmp\esp32\moddable_two\debug\helloworld\makefile(216) : fatal error U1050: Detected ESP-IDF version v4.2.1. Expected ESP-IDF version v4.2.
Stop.

I checked espressif/esp-idf (https://github.com/espressif/esp-idf/tree/release/v4.2) that they actually update v4.2 to v4.2.1 a month ago, and there is no available v4.2 so far. I know there might be some version check in makefiles.

Any solution?

That's annoying. Assuming there are no incompatible changes, you should be able to change the version check. In make.esp32.mk on macOS/Linux or nmake.esp32.mk on Windows, change the EXPECTED_IDF from 4.2 to 4.2.1:

EXPECTED_ESP_IDF ?= v4.2.1

So far it works great. It seems like all changes are compatible.

Cool. Thanks for confirming. Seems to work here too. We'll make that change for our next SDK update.
