Code:

    xtensa-lx106-elf-macos-1.22.0-100-ge567ec7-5.2.0.tar.gz

Then I cloned the release/v3.3 branch of ESP8266_RTOS_SDK. This caused the build to fail on my project with:

Code:

CC build/lwip/lwip/src/api/if_api.o

So I went back to the examples and tried building:

Code:

    ESP8266_RTOS_SDK/examples/get-started/hello_world

and got the same error. It looks like there's some conflict in including two different headers with the same definitions. Has anyone seen this? For the hello_world example I first ran 'make menuconfig' using all the default values.
