ESP32: recipe.preproc.macros pattern is missing

Using Arduino IDE 1.x
1

I am using the IDE version 1.8.13 and updated my esp32 by Espressif to 2.0.13 yesterday through the Board Manager and now I get the error:

recipe.preproc.macros pattern is missing

Error compiling for board ESP32 Dev Module.

I'm not sure what version I had before the update, but this was working perfectly until I updated.

Any ideas?

Hi @pdihawk. I just tried compiling for an ESP32 board in Arduino IDE 1.8.13 using version 2.0.13 of the "esp32" platform and did not experience any problems. So I think this error might have been caused by something going wrong during the update. That can often be fixed by removing and then re-installing the broken boards platform via Boards Manager.

Please try this:

  1. Select Tools > Board > Boards Manager from the Arduino IDE menus.
    A "Boards Manager" dialog will appear.
  2. Wait for the updates to finish, as shown by the messages printed at the bottom of the "Boards Manager" dialog.
  3. Scroll down through the list of boards platforms until you find the "esp32" entry. Click on it.
    Some buttons will appear on the entry.
  4. Click the "Remove" button on the "esp32" entry.
  5. Wait for the removal to finish.
  6. Click the "Install" button on the "esp32" entry.
  7. Wait for the installation to finish.
  8. Click the "Close" button on the "Boards Manager" dialog.

Now try compiling or uploading to your board again. Hopefully the error will no longer occur.

Perfect!

That solved my problem.
