問題與Qt的4.7.2

Question

建設的MySQL插件我這裏有以建設MySQL驅動程序使用Qt 4.7.2

我已經安裝的Qt 4.7.2 VS2008和MySQL 5.5.9社區版的連接體問題，無論是在沒有空格的路徑（C：\ Qt中，C：\ MySQL的）。 我把從Qt的文檔的命令和創建Makefile文件都沒有問題，只有消息：

C:\Qt\4.7.2\src\plugins\sqldrivers\mysql>C:\Qt\4.7.2\bin\qmake "INCLUDEPATH+=C:\MySQL\include" "LIBS+=C:\MYSQL\lib\libmysql.lib" mysql.pro 
WARNING: (internal):1: Unescaped backslashes are deprecated. 
WARNING: (internal):1: Unescaped backslashes are deprecated. 
WARNING: (internal):1: Unescaped backslashes are deprecated. 

然後我運行NMAKE，並得到以下結果：

C:\Qt\4.7.2\src\plugins\sqldrivers\mysql>nmake

在了Qt -Doc是MySQL庫的另一個路徑，但是我改變了它。我沒有選擇路徑，在libaries該文件夾中的上方。

我試圖在VS2008/2010命令提示符下構建插件，沒有任何區別。

希望有人能幫助我，謝謝

Answer 1

MasterMito找到解決方案himself：

解決了這一問題：安裝了MySQL，服務器的32位版本。

Answer 2

安裝32位版本解決了我的問題。 但是，這樣做確保已安裝的版本完全去除和MySQL服務沒有運行。你可以從任務管理器 - >服務中查看。如果服務已經運行，您可以停止服務。

執行實例配置時，安裝mysql-5.5.33-win32.msi時總會導致掛起。所以，我安裝了zip並手動啓動了mysql服務。
