Qt應用程序：無法加載平臺插件「窗口」。可用的平臺是：

Question

我編譯的Qt 5.0.0與msvc2010，因爲我需要配置字符串

configure -prefix %CD%\qtbase -opensource -nomake -nomake examples -nomake demo -opengl desktop -platform win32-msvc2010 

的OpenGL現在我就可以開始從只QtCreator Qt應用程序。我已經把應用程序在WinDBG的輸出下面

CommandLine: D:\work\workspace\WellReader_0_1-build-Qt_5_0_0_msvc2010_opengl-Release\release\WellReader_0_1.exe

我可以採取插件「窗口」？或者我應該用另一個配置選項重新編譯Qt？請指教

Answer 1

我還沒有看Qt 5.0，但如果他們現在有插件平臺，你必須確保你的應用程序可以在運行時找到它們。顯然QtCreator正確設置了PATH，所以所有的插件都在那裏，不需要重新編譯Qt。

找到plugins文件夾，將必要的插件複製到您的安裝文件夾中（確保保持結構，例如「plugins/imageformats /.../ bla.dll」等），創建qt.conf文件並將plugins路徑設置爲是「。」。將qt.conf文件也放到安裝文件夾中。
