Qt创建者2.5：意外的GDB退出，我怎么知道为什么GDB崩溃了？

标签： windows qt gdb qt-creator

我使用从Qt网站下载的mingw下载了QT Creator 2.5：MinGW-gcc440_1 在QT Creator 2.5和windows global PATH中设置路径。 我在编译时调试模式，但是当我尝试使用GDB进行调试时 我在错误信息窗口中收到此错误：标题中出现意外的GDB退出，gdb进程崩溃了。 即时通讯使用Windows 7,64位，但g ++正在编译为32位， 我试图在QT Creator 2.5中搜索一些没有运气的日志..

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：

答案 0 :(得分：0)

那个gdb是6.8版。 IIRC Creator建议使用7.0，那么您是否尝试过升级GDB？

你从哪里获得GDB？一些mingw发行版中提供的版本在Qt Creator中使用时会被破坏。您可以从此处获取Qt Creator团队认为可以使用的一个：http://builds.qt-project.org/
