Windows Qt creator 2.5：意外的GDB退出，我如何知道GDB崩溃的原因？

我下载了QtCreator 2.5，使用的是我从QT站点下载的mingw，名为：mingw-gcc440_1 在QT Creator 2.5和windows全局路径中设置路径。 当我编译时，我处于调试模式，但当我尝试使用GDB进行调试时 我在错误消息窗口中收到此错误：标题中出现意外的GDB退出，GDB进程崩溃。 我使用的是64位windows 7，但g++是32位编译， 我试图在QT Creator 2.5中搜索一些日志，但运气不佳

编译行示例：

g++ -c -g -frtti -fexceptions -mthreads -Wall -DUNICODE -DQT_LARGEFILE_SUPPORT -DQT_DLL -DQT_GUI_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_THREAD_SUPPORT -DQT_NEEDS_QMAIN -I"c:\Qt\4.8.2_mingw\include\QtCore" -I"c:\Qt\4.8.2_mingw\include\QtNetwork" -I"c:\Qt\4.8.2_mingw\include\QtGui" -I"c:\Qt\4.8.2_mingw\include" -I"." -I"lib_json\include" -I"lib_json\include\json" -I"c:\Qt\4.8.2_mingw\include\ActiveQt" -I"debug" -I"." -I"c:\Qt\4.8.2_mingw\mkspecs\win32-g++" -o debug\main.o main.cpp

好的，我有调试器的日志，但我很难找到问题：

该gdb是版本6.8。IIRC Creator推荐7.0，那么您是否尝试过升级GDB

---

你从哪里得到的GDB？一些mingw发行版中提供的一个已知在使用Qt Creator时会损坏。您可以从这里找到一个Qt Creator团队认为可以使用的工具：

如果您使用64位编译，它可以使用吗？我没有尝试使用64位编译，我需要它使用32位。您是否在优化代码上运行调试器？我想知道您是否在经过优化的代码上设置了断点。我用编译行示例更新了这个问题
