I am using the ESP8266_RTOS_SDK trying to write my first app.
I use the COMPONENT_EMBED_TXTFILES feature in the component.mk to embed some certificate (PEM).
The following code then embeds the certificate and corresponding key:
static uint8_t d_client_crt_start asm("_binary_client_crt_start");
static uint8_t client_crt_end asm("_binary_client_crt_end");
static uint8_t client_key_start asm("_binary_client_key_start");
static uint8_t client_key_end asm("_binary_client_key_end");
When I put this code in a .c file, it works flawlessly, however if this is in a .cpp file, i get the following
error during compilation:
app.cpp:45:16: error: storage size of 'client_crt_start' isn't known
static uint8_t client_crt_start asm("_binary_client_crt_start");
For now, I have put the embedding code into a separate .c file but I really would like to have it
in the main app.cpp. I am unfamiliar with using gcc's asm(...) in C++, so I would appreciate
any help here.
