error: implicit declaration of function 'esp_tls_conn_delete' (CA-319)

[anoopkumares]

I am trying to compile iothub_client_sample_mqtt example. I have cloned esp-idf repo and this repo. but while building the code (idf.py build), I am getting the following error:

tlsio_esp_tls.c:127:5: error: implicit declaration of function 'esp_tls_conn_delete'; did you mean 'esp_tls_conn_write'? [-Werror=implicit-function-declaration] 127 | esp_tls_conn_delete(tls_io_instance->esp_tls_handle);

How can I fix this error ?

@anoopkumares This is because you compile with esp-idf v5 Change from esp_tls_conn_delete to esp_tls_conn_destroy

I fixed that. But I am getting another error. tlsio_esp_tls.c:219:59: error: invalid application of 'sizeof' to incomplete type 'esp_tls_t' {aka 'struct esp_tls'} 219 | result->esp_tls_handle = calloc(1, sizeof(esp_tls_t)); | ^~~~~~~~~ [14/84] Building C object esp-idf/port...iot-sdk-c/c-utility/src/sastoken.c.obj ninja: build stopped: subcommand failed.

@anoopkumares Just try to allocate fixed memory, in my case seems that 2*1024 works as expected.

            // result->esp_tls_handle = (esp_tls_t*)calloc(1, sizeof(esp_tls_t));
            //ToDo: esp-idf v5.1.1 compilation problem of un-complete type sizeof(esp_tls_t), below is a workaround
            result->esp_tls_handle = (esp_tls_t*)calloc(1, 2*1024);
