Hi there!
I've got problems compiling code based on SDK. Particularly, I've got compiler complains about stdint.h file.
The error:

Code: Select all

/opt/Espressif/ESP8266_SDK/include/stdint.h:83:5: error: "TENSILICA" is not defined [-Werror=undef]
 #if TENSILICA || 1

Hope anybody knows how to fix it.
Thanks in advance,

Though the header doesn't look particularly clean I guess the easiest fix would be not using -Werror in your compiler flags.

How?

I use stdint.h all of the time, no problems. Looks a bit like your gcc/build environment didn't install correctly.
