'RTC_IO_PAD_DAC2_REG' was not declared in this scope
Issue #266
resolved
hi,
I use a new computer recently (MacOS 12.3.1 M1) . When I build esp32 ：`pio run -e esp32`
I encountered this problem:
'RTC_IO_PAD_DAC2_REG' was not declared in this scope
Here are the details:
PLATFORM: Espressif 32 (4.2.0) > DOIT ESP32 DEVKIT V1
HARDWARE: ESP32 240MHz, 320KB RAM, 4MB Flash
DEBUG: Current (cmsis-dap) External (cmsis-dap, esp-prog, iot-bus-jtag, jlink, minimodule, olimex-arm-usb-ocd, olimex-arm-usb-ocd-h, olimex-arm-usb-tiny-h, olimex-jtag-tiny, tumpa)
PACKAGES:
- framework-arduinoespressif32 3.20002.220503 (2.0.2)
- tool-esptoolpy 1.30300.0 (3.3.0)
- toolchain-xtensa-esp32 8.4.0+2021r2-patch3
Converting vm.ino
Did I do something wrong?

P.S. You can still install a working ESP32 VM from the MicroBlocks IDE. Of course, that won't help if you are working on the VM code.

Markus Gälli reported this:
Needed to add #include "soc/rtc_io_reg.h" otherwise it wasn’t building.
Looks like you need to add that header file (inside an ESP32 ifdef) to ioPrims.cpp.
See Markus' PR to see where he added it.

I am writing a library for a pixel pack, the current NeoPixel library still have some burrs on ESP32 (but much better than before), I want to try some adafruit NeoPixel drivers

I've added the header file to the dev branch of the repository. Also fixed some new compiler warnings introduced by the updated ESP32 compiler.

You didn't do anything wrong; a recent ESP32 package update introduced this issue.
I am still using 3.10006.210326, which does not give this error. It looks like a recent update to the Platformio Espressif 32 package introduced the compile error. Kathy reported a problem compiling MicroBlocks for the ESP32 a few days ago, probably this same issue.
I'm guessing we just need to include an extra header file. In fact, I think someone reported that fix but I've been traveling so I am behind on issue tracking.
I will sort this out soon. Thanks for reporting it!
