It works when adding -lm to the parameters:

$ gcc -O2 -lm *.c -o adpcm-xq
$ ./adpcm-xq

 ADPCM-XQ   Xtreme Quality IMA-ADPCM WAV Encoder / Decoder   Version 0.5
 Copyright (c) 2024 David Bryant. All Rights Reserved.

 Usage:     ADPCM-XQ [-options] infile.wav outfile.wav

 Operation: conversion is performed based on the type of the infile
          (either encode 16-bit PCM to 4-bit IMA-ADPCM or decode back)

 Options:  -[0-16]= encode lookahead samples (default = 3, max = 16)
           -b<n>  = override auto block size, 2^n bytes (n = 8-15)
           -d     = decode only (fail on WAV file already PCM)
           -e     = encode only (fail on WAV file already ADPCM)
           -f     = encode flat noise (no noise shaping, aka -s0.0)
           -h     = display this help message
           -n     = measure and report quantization noise
           -q     = quiet mode (display errors only)
           -r     = raw output (little-endian, no WAV header written)
           -s<n>  = override default noise shaping, (-1.0 < n <= 1.0)
           -v     = verbose (display lots of info)
           -w<n>  = override default 4-bit ADPCM width (2 <= n <= 5)
           -x     = exhaustive search (old behavior, very slow at depth)
           -y     = overwrite outfile if it exists

Thanks for reminding me of this!

Yeah, the README needs several updates (all the new features!) and I was planing to upgrade to Markdown.

Updated README to Markdown and fixed build instructions.
