如何在Mac OS X 10.6.6上安装mysql和ruby以及mysql / ruby

Question

如何在Mac OS X 10.6.6上安装mysql和ruby以及mysql / ruby​​？我收到了这个错误：

 checking for mysql_query() in -lmysqlclient... no

 ld: warning: in /usr/local/mysql/lib/libmysqlclient.dylib, 
     file was built for unsupported file format which is not the
     architecture being linked (i386)

转到http://macruby.org/downloads.html并下载并安装http://macruby.org/files/MacRuby%200.8.zip。

转到http://mysql.com/downloads/mysql/并下载Mac OS X版。 10.6（x86,64位），DMG档案。

转到http://tmtm.org/en/mysql/ruby/并按照步骤下载，然后：

1. 运行命令：ruby extconf.rb --with-mysql-config
2. 在文本编辑器中修改文件“Makefile”并删除所有i386架构标志，即"-arch i386"
3. 运行命令：make
4. 运行命令：make install
5. 运行命令：export rvm_archflags="-arch x86_64"
6. 运行命令：export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
7. 运行命令：ruby test.rb
8. 运行命令：ruby ./test.rb -- [hostname [user [passwd [dbname [port [socket [flag]]]]]]]

注意：

如果在测试时遇到类似'libmysqlclient not found'的错误，则需要指定库所在的目录，以便make可以找到它。

% env LD_RUN_PATH=libmysqlclient.so directory make

示例：

my = Mysql.new(hostname, username, password, databasename)
st = my.prepare("insert into tblname (col1,col2,col3) values (?,?,?)")
st.execute("abc",123,Time.now)
st.prepare("select col1,col2,col3 from tblname")
st.execute
st.fetch  # => ["abc", 123, #<Mysql::Time:2005-07-24 23:52:55>]
st.close

Dan Benjamin的Hivelogic非常适合：http://hivelogic.com/articles/compiling-mysql-on-snow-leopard和http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard。虽然Snow Leopard已经拥有Ruby 1.8.7。
