error: 'rtc_gpio_desc' undeclared

I am having a trouble with the error: 'etc_gpio_desc'

App "esp32-homekit-camera" version: 2a26d79 CC build/esp32-camera/driver/twi.o /home/ubuntucamera/esp/esp32-homekit-camera/components/esp32-camera/driver/twi.c: In function 'pinMode': /home/ubuntucamera/esp/esp32-homekit-camera/components/esp32-camera/driver/twi.c:61:24: error: 'rtc_gpio_desc' undeclared (first use in this function); did you mean 'rtc_io_desc'? uint32_t rtc_reg = rtc_gpio_desc[pin].reg; ^~~~~~~~~~~~~ rtc_io_desc /home/ubuntucamera/esp/esp32-homekit-camera/components/esp32-camera/driver/twi.c:61:24: note: each undeclared identifier is reported only once for each function it appears in /home/ubuntucamera/esp/esp-idf/make/component_wrapper.mk:291: recipe for target 'driver/twi.o' failed make[1]: *** [driver/twi.o] Error 1 /home/ubuntucamera/esp/esp-idf/make/project.mk:604: recipe for target 'component-esp32-camera-build' failed make: *** [component-esp32-camera-build] Error 2

I executed the command make menuconfig and set the parameters.
when I try to flash i got the error above.
Anyone experienced that?
thanks

I#m having the same problem. Trying all night to get it running with no sucess :-(

There is a setting on latest ESP-IDF you need to enable for this project. I’m afk now, but you should be able to find it somewhere in component configs -> device configurations -> rtc something. Just enable it and it will compile.

Thanks alot for your answer. I found it and now my camera is online. Great project by the way!

thanks a lot Maxim
It is in Component config > driver configurations > RTCI0 configuration

thanks again

Thank you, extremely useful, I was stuck on this for 1 hour...

I have the same problem, fighting with this. Arduino w ESP support added. First under Linux, now on Windows, with this project:
https://www.hackster.io/anatoli-arkhipenko/multi-client-mjpeg-streaming-from-esp32-47768f

Same problem both on Linux as Windows
exit status 1 'rtc_gpio_desc' undeclared (first use in this function)
twi.c uses rtc_gpio_desc and it requires Component config > driver configurations > RTCI0 configuration > "Support array 'rtc_gpio_desc' for ESP32
I do not use make menuconfig so is there another way I can fix this, a file somewhere to edit?

@krambriw Same here :(

Component config > driver configurations > RTCI0 configuration this option is missing in the actual ESP-IDF 5.0.1
