Fehlermeldung: Fehler beim Kompilieren für das Board ATtiny84 @ 1 MHz (internal

Oh dankeschön. Das habe ich nun gefunden.
Allerdings kann ich das Programm noch nicht hochladen:
Das ist der Code:

/*

This is an attiny84 example code for the nRF24L01 that can communicate with RF24 library

All the support files and libraries for the attiny for nRF24L01 is at repo listed  below

 *  repo   : https://github.com/stanleyseow/arduino-nrf24l01/
 *  Author : Stanley Seow

 Some default values to take note when using this mirf/spi85 library
 Uses Mirf forked library from https://github.com/xdarklight/arduino-nrf24l01
 
 - node addressing is similar to RF24 libs but the bytes are flipped 
 
   byte TADDR[] = {0xe3, 0xf0, 0xf0, 0xf0, 0xf0}; will matches receiver node of RF24 below 
   const uint64_t pipes[2] = { 0x7365727631LL, 0xF0F0F0F0E3LL };
 
 The repo for the RF24 lib is at https://github.com/stanleyseow/RF24/

 Added TinyDebugSerial to the codes for TX only serial debugging
