配置：

  • OS X 狮子 10.7.5
  • 通过 xcode462_cltools_10_76938260a.dmg 安装的 XCode 命令行工具
  • MySQL 通过 mysql-5.6.12-osx10.7-x86_64.dmg 安装
  • ruby-1.9.3-p327 通过 rvm

发射：

sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib   --with-mysql-include=/usr/local/mysql/include --with-mysql-config=/usr/local/mysql/bin/mysql_config

结果是：

Building native extensions.  This could take a while...
ERROR:  Error installing mysql2:
    ERROR: Failed to build gem native extension.

        /Users/edo/.rvm/rubies/ruby-1.9.3-p327/bin/ruby extconf.rb --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib --with-mysql-include=/usr/local/mysql/include --with-mysql-config=/usr/local/mysql/bin/mysql_config

和更多。

有什么建议吗？
