Library working with Digispark ATTiny85

[OscarBaksa]

Hi, very interesting library.
Tried on Arduino IDE 2.2.1:

• Compiled on Arduino UNO = Works
• Compiled on DIGISPARK ATTINY85 = Not compile I have the following error:
  ...\libraries\RBD_Threshold\RBD_Threshold.cpp.o: In function RBD::Threshold::Threshold(int)': ...\libraries\RBD_Threshold\src/RBD_Threshold.cpp:12: undefined reference to operator new[](unsigned int)'

I am not so advanced in C++ and I can't understand the error.
Where am I wrong ?
Help appreciated.
Many thanks
