ESP-SKAINET not building in C++. (AIS-1370) #116

Closed nikhil-robinson closed 9 months ago

I was testing the esp-skainet example en_speech_commands_recognition on the esp32s3eye board the example builds fine but when i change the man.c to main.cpp i am getting some undefined reference warnings.

Is it not posible to compile in c++ ?

Idf version : ESP-IDF v5.1.1-dirty SOC: esp32s3 sdkconfig : the default one from the example

@feizi this issue is solved when manually changing the the esp-sr to the latest commit. Missing some.

#ifdef __cplusplus
extern "C" {
#endif

#ifdef __cplusplus
}
#endif

in the header files.
