Proliferation of unknown files in QtCreator 4.8.1

  • Every time I run a program (or so it seems) in Qt Creator, I get another empty file in the project directory named something like


    Any clue where they come from, what they are for, and why they aren't in the apparent/proper temporary file location?

    This didn't happen before I installed 4.8.1 some weeks back.

    Hi @drmhkelley,

    • on which platform are you?
    • which build system do you use?
    • do you use shadow-builds?


  • @aha_1980 I'll try to provide this information.

    First, I noticed that the two such files get created each time I start the debug mode in Qt Create - none if I run without the debugger.

    Platform: Windows 10
    Build System: (not certain what you mean) Use qmake to generate the relevant Makefiles, mingw32-make to process the Makefiles, then MinGQ-w64 for compilation and linking and debugging. Specifically, compile and link with a version of Gnu C++ (MinGW-w64\x86_64-7.2.0-posix-seh-rt_v5-rev1\mingw64\bin\g++) and the corresponding Gnu debugger (MinGW-w64\x86_64-7.2.0-posix-seh-rt_v5-rev1\mingw64\bin\gdb).

    Shadow-builds: don't know what this is so likely don't use it.
