I have downloaded the ros micro libary from this repo. I followed this guide and updated the platform.txt files using this guide. I tested this with the old and the new Arduino IDE for a Teensy 4.0 board. But when compiling an example sketch from the ROS-Micro library I get the following error message.

It seems that _localectype_ptr is undefined? This is my first time using ROS or ROS-Micro and I am trying to get message from a Teensy 4.0 via Serial to a ROS Iron project running on a linux machine. (For now in a VirtualBox, but later natively)

I googled but I can't seem to find a solution. Can anyone help?
