  • Target version: current: 2.2.0
  • ruby -v: 2.1.0 and later
  • Backport: 2.0.0: UNKNOWN, 2.1: DONE

ruby 2.1以降で configure に --with-opt-dir=/opt/local を指定すると、

  • checking for printf prefix for long long… が、 clang の吐く clang:
    warning: argument unused during compilation: ‘-I /opt/local/include’
    のせいで失敗し、 config.h に PRI_LL_PREFIX の定義が入らない

  • compiling …/ext/-test-/num2int/num2int.c がこけてビルド失敗

という流れです。

パッチを添付します。
