std::map error: undefined reference to std::_Rb_tree_decrement

[dbh97]

Hi. I am trying to use std::map, but am getting errors.
I am using a Teensy 3.1. I have tried both the Arduino software and Make. I am running ArchLinux.

MNWE:

#include "stdlib.h"
#include "map"

void setup() {
  // put your setup code here, to run once:
 std::map<int, int> foobar;
 foobar[1] = 5;
}

void loop() {
  // put your main code here, to run repeatedly:

}

Error:

Is std::map not usable on the Teensy?

The C++ standard library is normally not linked. There are people who have used it, this thread shows what you need to do:

Thanks! That's just what I was looking for!

For anyone encountering a similar issue with Map for use in SAMD21 Pro RF using Arduino IDE with arm-none-eabi-gcc version 4.8.3-2014q1. Or Arduino take a look at this repository github.com/Potsdam-Sensors/CPPMap
