Fastled library Arduino

[leibhold]

using the example sample project WS2812 NeoPixel Arduino Button Cycler,
replacing the Adafruit_NeoPixel.h with Fastled.h and removing most of the code for a simple main.ino


On build I get this error

FastLED.h:302: undefined reference to `__cxa_guard_acquire'
FastLED.h:302: undefined reference to `__cxa_guard_release'

Is there a compiler directive to prevent this error ?

Hello,

Quick search in Google tells that you need to remove -std=gnu++11 from the compiler options.

Thank you, I did eventually find that but it results in a host of other errors

example

/Arduino/libraries/FastLED/src/platforms/avr/clockless_trinket.h:225:120: warning: asm operand 18 probably doesn't match constraints
or
/Arduino/libraries/FastLED/src/platforms/avr/clockless_trinket.h:254:48: error: impossible constraint in 'asm'


ending in

Error code 2

these all appear to be related to /Arduino/libraries/FastLED/src/platforms/avr/clockless_trinket.h


I think I may have to assume fastled will not be an option here
