std::make_unique

[hsaturn]

Hello, EpoxyDuino does not support std::make_unique.

I've used this implementation that work like a charm. https://github.com/bstreiff/cppbits/blob/master/make_unique.h

Is it possible to add it to EpoxyDuino please ?

Best regards

It's probably related to EpoxyDuino defaulting to -std=gnu++11. It looks like std::make_unique is a C++14 feature.

• AVR uses gnu++11: https://github.com/arduino/ArduinoCore-avr/blob/master/platform.txt#L28
• ESP32 2.0.5 also uses gnu++11: https://github.com/espressif/arduino-esp32/blob/master/platform.txt
• Adafruit SAMD uses gnu++11: https://github.com/adafruit/ArduinoCore-samd/blob/master/platform.txt#L42
• STM32 is at gnu++14: https://github.com/stm32duino/Arduino_Core_STM32/blob/main/platform.txt#L64
• ESP8266 3.0.2 seems to be at gnu++17: https://github.com/esp8266/Arduino/blob/master/platform.txt#L43
• Teeny3, Teensy4 seems to be atgnu++14:
  • https://github.com/PaulStoffregen/cores/blob/master/teensy3/Makefile#L103
  • https://github.com/PaulStoffregen/cores/blob/master/teensy4/Makefile#L127
  • It's hard to tell because Teensy installs its Arduino core in a different way than other cores

I don't know. As you saw, I am getting tired of C++ and I don't have the energy to keep up with the exploding complexity of C++ anymore. But if ESP8266 uses gnu++17, and you want to compile ESP8266 code, I guess EpoxyDuino should support that. So the solution seems to be to use gnu++17 when EPOXY_CORE is set to EPOXY_CORE_ESP8266.

I might be able to look at this in about 1-2 weeks...

Hello Brian

I knew about the fact that C++ becomes boring for you (same for me in fact). And you're right, make_unique is not supported every where on arduino's ides so....

You may close this 'issue'. I'll deal with this another way.

So may be the long term solution is to add additional EPOXY_CORE_XXX flavors, so that different flavors specify different C++ versions of the different Arduino targets.

So something like:

• EPOXY_CORE_ARDUINO_AVR: gnu++11
• EPOXY_CORE_SPARKFUN_AVR: gnu++11
• EPOXY_CORE_ATTINY: gnu++11
• EPOXY_CORE_STM32: gnu++14
• EPOXY_CORE_SEEEDUINO_SAMD: gnu++14
• EPOXY_CORE_ARDUINO_SAMD: (not compatible with EpoxyDuino)
• EPOXY_CORE_SPARKFUN_SAMD: gnu++11
• EPOXY_CORE_ADAFRUIT_SAMD: gnu++11
• EPOXY_CORE_ADAFRUIT_NRF52: gnu++11
• EPOXY_CORE_ESP8266: gnu++17
• EPOXY_CORE_ESP32: gnu++11
• EPOXY_CORE_TEENSYDUINO: gnu++14

?? These are just the ones that I know about.

This is a lot of work, which is not very interesting, so it has not been high on my priority list. My personal solution is to just stick to C++11, so that I don't have to worry about compatibility with all the different Arduino APIs out there.

I guess since there is currently a EPOXY_CORE_ESP8266 flavor, it is probably worth changing that target to gnu++17, to match the C++ version used by the actual ESP8266 Core.
