Rails/Snow Leopard Mysql 64位問題

Question

嘿，我試圖在Snow Leopard上爲Rails應用程序安裝64位MySQL。

我已經從dmg安裝了它，我可以從命令行使用mysql。基於各種博客文章，以及其他主題這裏堆棧，我關閉mysql的，卸載MySQL的寶石，然後嘗試更新以下的寶石：這會產生以下

sudo env ARCHFLAGS='-arch x86_64' gem install --verbose --no-rdoc --no-ri mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config 

：

1 gem installed 

這兩個警告在最後似乎不祥。然後我去我的Rails應用程序和運行

rake db:migrate 

並獲得：

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 

這就是據我能夠得到。我試過通過dmg和macports安裝MySQL，我似乎在兩種情況下都遇到了這個錯誤。

當談到鐵軌時，我是一個小菜鳥;任何人都可以擺脫的任何光線都會受到狂歡。謝謝！

在回答約翰的（和khelll的）答案如下：

當我這樣做，約翰指定的第一個命令，我得到：

No definition for next_result 

No definition for field_name 

No definition for field_table 

這裏有大約40行。我認爲這是因爲文檔。但是，當我做耙分貝：遷移我得到：

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命令產生我前面指定的錯誤。

---第二個編輯---

我要補充一點，我沒有不從源代碼安裝。再次偷看Hivelogic的指示後，我走下了這條路。

當我試圖運行：

./configure --prefix=/usr/local/mysql --with-extra-charsets=complex \ 
--enable-thread-safe-client --enable-local-infile --enable-shared \ 
--with-plugins=innobase 

我：

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：

sudo port deactivate gettext 
sudo port activate gettext @0.17_3 

然而，以下所有步驟，重新安裝寶石後，在耙db：遷移我仍然得到：

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 
    Expected in: flat namespace 
in /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle 
Trace/BPT trap 

----第三編輯----

好了 - 我相信這裏發生了什麼的是，即使我上面指定的64位創業板，它在安裝32位版本。我做的：

file /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle 

並獲得：

/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裝32位版本

我安裝了它從源代碼如下these instructions on Hivelogic和它的偉大工程。 「 - 拱x86_64的」 寶石安裝mysql - --with-mysql的-配置=在/ usr /本地/ MySQL的須藤ENV ARCHFLAGS =：
