Error with Custom IRremote library

Using Arduino Programming Questions
1

Hey guys,
I am trying to use some older code with my Arduino UNO, which I got here: GitHub - afaucher/LazerTagHost: A laser tag host for Phoenix LTX and LTTO type guns
It is a modified IRrelay, and it is using a modified library, so I can't just use the standard IRremote library.

I figured out the Wprogram.h thing and corrected that in the library.

However, I am now getting the following error when I try to verify the code, and I am not quite sure what to do to resolve it.

IRremote/IRremote.cpp.o: In function `IRrecv::decode(decode_results*)':
/home/redfoxdude/sketchbook/libraries/IRremote/IRremote.cpp:385:(.text._ZN6IRrecv24decodeLAZER_TAGEP14decode_results+0x70): relocation truncated to fit: R_AVR_7_PCREL against `no symbol'
collect2: error: ld returned 1 exit status

I think these are the relevant pieces from the library code:

long IRrecv::decodeLAZER_TAG(decode_results *results) {
  unsigned long data = 0;
  int offset = 1;
  int i = 0;
  
  results->bits = 0;
  
  //HEAD
  if (results->rawlen < 14) {
    return ERR;
  }
  if (!MATCH_MARK(results->rawbuf[offset], LTTO_HDR_MARK_ONE)) {
    return ERR;
  }
  offset++;
  if (!MATCH_SPACE(results->rawbuf[offset], LTTO_HDR_SPACE)) {
    return ERR;
  }
  offset++;
  if (!MATCH_MARK(results->rawbuf[offset], LTTO_HDR_MARK_TWO)) {
    return ERR;
  }
  offset++;
  //DATA
  for (i = 0; i < (results->rawlen - 4); i++) {
    if (i % 2 == 1) {
	    if (MATCH_MARK(results->rawbuf[offset], LTTO_ONE_MARK)) {
		    data <<= 1;
		    data |= 1;
		    results->bits++;
	    } else if (MATCH_MARK(results->rawbuf[offset], LTTO_ZERO_MARK)) {
		    data <<= 1;
		    data |= 0;
		    results->bits++;
	    } else {
	      Serial.println(i, DEC);
	      return ERR;
	    }
	  } else {
	    if (!MATCH_SPACE(results->rawbuf[offset], LTTO_SPACE)) {
		    Serial.println(i, DEC);
	      return ERR;
	    }
	  }
	  offset++;
  }
  
  // Success
  results->value = data;
  results->decode_type = LAZER_TAG;
  return DECODED;
}

and

// Decodes the received IR message
// Returns 0 if no data ready, 1 if data ready.
// Results of decoding are stored in results
int IRrecv::decode(decode_results *results) {
  results->rawbuf = irparams.rawbuf;
  results->rawlen = irparams.rawlen;
  if (irparams.rcvstate != STATE_STOP) {
    return ERR;
  }

If anyone could assist me in remedying this issue, that would be awesome!
Thanks,
RFD

I edited my original post to add some code from the custom library which I hope is relevant!
