mysql - 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？我收到此错误:

 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 版本。 10.6(x86，64 位)，DMG 存档。

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:

如果在测试时出现类似'libmysqlclient not found'的错误，需要指定库所在的目录，以便make能够找到它。

% env LD_RUN_PATH=libmysqlclient.so directory make

例子:

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
