Problem----cannot hit F5

My program don't have any problem, because it is running by Ctrl+R
but now I can't debug it, and the system prompts "This binary type 'x86-windows-msys-pe-32bit' debug engine can debug 'Gdb engine, Cdb engine' is set correctly."
I don't know what happend, Why is there such a mistake??


Just now I set a new tool chain(compiler:D:\QtSDK\mingw\bin\gcc.exe and debugger:D:\QtSDK\mingw\bin\gdb.exe)
and debug it, gdb crashed

\QtSDK\mingw\bin\gdb.exe is a gdb build from MinGW. that's not working. there is another gdb.exe somewhere in \QtSDK\pythongdb. use this.

I used a new gdb.exe(build 7.5), and now it's normal about Qt.
