问题
I have a Qt 5.4 project on Windows 7 using MSVC 2013 and the CDB debugger. When I attempt to debug the program, the debug log shows that the debugger crashes. I can run the program without debugging.
The relevant error message is
Cannot execute '"C:...\Qt\build-GENOVA->Clone_of_Desktop_Qt_5_4_0_MSVC2013_64bit-Debug\debug\GENOVA.exe"', Win32 error > 0n50 "The request is not supported." Debuggee initialization failed, Win32 error 0n50 "The request is not supported."
What's going on here?
回答1:
Go to Qtcreator->option->build&run->debuggers to see the version of your cdb.
It may because you are using a 32bit cdbto debug a 64bit program. if it is 32bit, Try to uninstall it and install 64bit one.
If your cdb is 64bit, try to use windbg.exe(at the same folder of cdb.exe) to open your executable file to see more error details.
