Question

我用msvc2010编译了Qt 5.0.0，因为我需要配置字符串的opengl

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

现在我只能从QtCreator启动Qt应用程序。我已将应用程序放在WinDBG中，它的输出位于

之下

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