Encountering this error on the latest build:

/home/user/php-ext-brotli/brotli.c: In function ‘zm_info_brotli’:

The definition of BROTLI_LIB_VERSION is done in config.m4.

65: AC_DEFINE_UNQUOTED(BROTLI_LIB_VERSION, "$LIBBROTLIDEC_VERSION", [system library version])
69: AC_DEFINE_UNQUOTED(BROTLI_LIB_VERSION, "1.0.1", [bundled library version])

What did the configure option specify?

• Built in (v1.0.1)

  % git clone --recursive --depth=1 https://github.com/kjdev/php-ext-brotli.git
  % cd php-ext-brotli
  % phpize
  % ./configure
  % make  # OK
  

• System library (v0.6.0 on Fedora 26)

  % git clone --recursive --depth=1 https://github.com/kjdev/php-ext-brotli.git
  % cd php-ext-brotli
  % phpize
  % ./configure --with-libbrotli
  % make # OK
  

  % pkg-config libbrotlidec --modversion
  0.6.0

This fixed the problem:

./configure --with-libbrotli
