clock_gettime() not compiling

Hello, I cannot get the Arduino IDE to find and compile `clock_gettime()`. My error is: `'clock_gettime' was not declared in this scope` Here's the simple sketch: #include "time.h" struct timespec tp; void setup() { Serial.begin(115200); } void loop() { double tNow; long dt_sec, dt_nsec; clock_getti...

Re: esp32 newlib migration or access via Arduino ide

Ok, if the newlib .a library is there (I checked - it is) and the headers are there (I checked, time.h and others are there), then something in the `#define`'s are not triggering `clock_gettime()`. I'm getting: `'clock_gettime' was not declared in this scope` I need a `clock_gettime()` example that ...

I've used the Arduino IDE instructions using the Board Manager and the Stable Release link: https://github.com/espressif/arduino-esp32/blob/master/docs/arduino-ide/boards_manager.md Th...

esp32 newlib migration or access via Arduino ide

Hello, The ESP32 devices are outstanding. I'm using the Arduino IDE but can also see some interesting code in the newlib github respository here: https://github.com/espressif/esp-idf/tree/master/components/newlib Is this going to be integrated into the Arduino ide library? Is there a (simple) way to...
