Rails / Snow Leopard Mysql 64
嘿所有，我试图安装在雪豹的64位MySQL的轨道应用程序。
我已经从dmg安装了它，并且可以从命令行使用mysql。 根据各种博客帖子以及Stack中的其他主题，我关闭了mysql，卸载了mysql gem，然后尝试使用以下命令更新gem：
sudo env ARCHFLAGS='-arch x86_64' gem install --verbose --no-rdoc --no-ri mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
这产生了以下结果：

最后这两个警告似乎不祥。 然后我去我的rails应用程序并运行
rake db:migrate
并得到：
dyld: NSLinkModule() error
dyld: Symbol not found: _mysql_affected_rows
Referenced from: /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle

Trace/BPT trap
而且就我所能得到的而言。 我试过通过dmg和macports安装MySQL，我似乎在两种情况下都遇到了这个错误。
当谈到铁轨时，我很喜欢小菜; 任何人都可以摆脱的任何光线都会受到狂欢。 谢谢！

回答John的（和khelll）答案如下：
当我执行约翰指定的第一个命令时，我得到：
No definition for next_result
No definition for field_name
No definition for field_table
这里有大约40行。 我认为这是因为文档。 但是，当我做耙分贝：迁移我得到：
dyld: NSLinkModule() error
dyld: Symbol not found: _mysql_affected_rows
Referenced from: /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
Expected in: flat namespace
in /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
Trace/BPT trap
使用ARCHFLAGS命令会产生前面指定的错误。
--- SECOND EDIT ---
我应该补充说我没有从源代码安装。 再次偷看Hivelogic的指示后，我走下了这条路。
当我试图运行时：
./configure --prefix=/usr/local/mysql --with-extra-charsets=complex
--enable-thread-safe-client --enable-local-infile --enable-shared
--with-plugins=innobase
我有：
config.status: creating zlib/Makefile
dyld: Library not loaded: /opt/local/lib/libintl.8.dylib
Referenced from: /opt/local/bin/gawk
Reason: no suitable image found. Did find:
/opt/local/lib/libintl.8.dylib: mach-o, but wrong architecture
./config.status: line 1782: 69228 Done(141) eval sed ç"ç$ac_sed_extraç" "$ac_file_inputs"
69229 Trace/BPT trap
所以我做了：
sudo port deactivate gettext
sudo port activate gettext @0.17_3
但是，遵循所有步骤后，重新安装宝石，在耙db：迁移我仍然得到：
dyld: NSLinkModule() error
dyld: Symbol not found: _mysql_affected_rows
Referenced from: /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle

好的 - 我相信这里发生的事情是，即使我指定了上面的64位宝石，它也安装了32位版本。 我做：
file /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
并得到：
/usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle: Mach-O bundle i386
所以它似乎我一直在安装32位版本
我按照Hivelogic上的这些说明从源代码安装了它，它工作的很好。 然后我使用以下方法安装MySQL RubyGem：
sudo gem install mysql -- --with-mysql-dir=/usr/local/mysql
