[ESP8266_NONOS_SDK-2.2.1] undefined reference to `__wrap_system_restart_local'

[sedlacek.david]

Hi, I'm porting my project to the ESP8266 platform. Everything seems to be fine, except that during linking the linker can't find these functions:

Code: Select all

__wrap_register_chipv6_phy
__wrap_system_restart_local

Am I missing some libraries? The complete error output is below.

Thank you very much, David.

Just in case someone would be interested in the future. The problem was that I copied someone's C flags and among the others there were the two missing functions!!! Omg. I spent five days scrutinising what is wrong. Yep. Five days gone.

Now everything works fine!!

-Wl,-wrap,system_restart_local -Wl,-wrap,register_chipv6_phy
