mbedtls threading c & pthread
Posted: Fri May 12, 2017 12:48 pm
I was trying to enable MBEDTLS_THREADING_C and MBEDTLS_THREADING_PTHREAD in:
mbedtls/port/include/mbedtls/esp_config.h
mbedtls/include/mbedtls/config.h
Resulting in a compiler error:
I saw a pthread_mutex_t defined in bt_defs.h and sys/types.h
I made a fix based on how bt_defs.h uses pthread_mutex_t that seems to fix that issue but is there another way?
I also have no clue if this fix is correct.

Threading.h:85
