Thanks. It works now. Taking a clue from another post, I did,
git checkout 3b92e85
on esp-idf

Then, it compiles without any error. I am able to flash and make it work as a STA.

@mschu7 should I change to a earlier version of esp-idf.

@lukasmaximus Tried the sample code given in https://github.com/m5stack/esp32-cam-demo as it is. Only change I did was from AP to STA in make menuconfig.

I bought a M5Stack ESP32 Camera. I am happy, it worked out of the box with the preloaded firmware. I wanted to change from AP to STA mode. While compiling the demo I get the following error. Can any one help.

CC build/main/app_main.o
