Code cannot compile with COSMIC STM8 compiler

[AN-sabik]

I try to use the printf in my STM8 project, whoch compiles fine if I use the standard library function. May I have issues to implement the following: "Implement your low level output function needed for printf()" -> I don't know how to do it.

I get the following error messages with cxstm8:
