Ошибка компиляции кода (tv-b пропал)

Я начал работать с arduino и нашел отличный онлайн-проект под названием tv-b gone. Он включает в себя некоторый код, который я не могу скомпилировать. Да, я включил main.h и worldcodes.cpp.

/*
TV-B-Gone for Arduino version 0.001
 Ported to Arduino by Ken Shirriff, Dec 3, 2009

 The original code is:
 TV-B-Gone Firmware version 1.2
 for use with ATtiny85v and v1.2 hardware

 With some code from:

 This is the 'universal' code designed for v1.2 - it will select EU or NA
 depending on a pulldown resistor on pin B1 !

This project transmits a bunch of TV POWER codes, one right after the other, 
 with a pause in between each.  (To have a visible indication that it is 
 transmitting, it also pulses a visible LED once each time a POWER code is 
 transmitted.)  That is all TV-B-Gone does.  The tricky part of TV-B-Gone 
 was collecting all of the POWER codes, and getting rid of the duplicates and 
 near-duplicates (because if there is a duplicate, then one POWER code will 
 turn a TV off, and the duplicate will turn it on again (which we certainly 
 do not want).  I have compiled the most popular codes with the 
 duplicates eliminated, both for North America (which is the same as Asia, as 
 far as POWER codes are concerned -- even though much of Asia USES PAL video) 
 and for Europe (which works for Australia, New Zealand, the Middle East, and 
 other parts of the world that use PAL video).

 Before creating a TV-B-Gone Kit, I originally started this project by hacking 
 the MiniPOV kit.  This presents a limitation, based on the size of
 the Atmel ATtiny2313 internal flash memory, which is 2KB.  With 2KB we can only 
 fit about 7 POWER codes into the firmware's database of POWER codes.  However,
 the more codes the better! Which is why we chose the ATtiny85 for the 
 TV-B-Gone Kit.

 This version of the firmware has the most popular 100+ POWER codes for 
 North America and 100+ POWER codes for Europe. You can select which region 
 to use by soldering a 10K pulldown resistor.

 Connect an IR LED to pin 3.

 Connect a pushbutton between pin 1 and ground.

/*
The C compiler creates code that will transfer all constants into RAM when 
 the microcontroller resets.  Since this firmware has a table (powerCodes) 
 that is too large to transfer into RAM, the C compiler needs to be told to 
 keep it in program memory space.  This is accomplished by the macro PROGMEM 
 (this is used in the definition for powerCodes).  Since the C compiler assumes 
 that constants are in RAM, rather than in program memory, when accessing
 powerCodes, we need to use the pgm_read_word() and pgm_read_byte macros, and 
 we need to use powerCodes as an address.  This is done with PGM_P, defined 
 below.  
 For example, when we start a new powerCode, we first point to it with the 
 following statement:
 PGM_P thecode_p = pgm_read_word(powerCodes+i);
 The next read from the powerCode is a byte that indicates the carrier 
 frequency, read as follows:
 const uint8_t freq = pgm_read_byte(code_ptr++);
 After that is a byte that tells us how many 'onTime/offTime' pairs we have:
 const uint8_t numpairs = pgm_read_byte(code_ptr++);
 The next byte tells us the compression method. Since we are going to use a
 timing table to keep track of how to pulse the LED, and the tables are 
 pretty short (usually only 4-8 entries), we can index into the table with only
 2 to 4 bits. Once we know the bit-packing-size we can decode the pairs
 const uint8_t bitcompression = pgm_read_byte(code_ptr++);
 Subsequent reads from the powerCode are n bits (same as the packing size) 
 that index into another table in ROM that actually stores the on/off times
 const PGM_P time_ptr = (PGM_P)pgm_read_word(code_ptr);
