The ONLY change to my system was moving from Xcode 9.4.1 to Xcode 10.1. When I stop the build the cmake process does go away along with the underlying ninja process (I used Ninja as the generator) but the all the clang processes are still going. I also went into the project settings for this project and replaced the default build command with "ninja". Now when I cancel the build all the processes stop. I also tried from the command line using "cmake --build . --target all" and let that spin up the 24 clang instances and then did a "ctrl-c" to kill the process and everything stopped like I would expect. So it looks like a strange interaction between QtCreator, CMake and Xcode 10.x.

I suppose when killing “not so nicely” the system might not care about subprocesses. Is the “cmake” process gone after you cancel the build? Is the behavior different for you with a previous Qt Creator version? I’m not aware of changes in Qt Creator in that regard. Br, Eike > On 9.

My project is CMake based which means the build command is something like 'cmake --build . --target ALL'. After I start the build if I want to stop the build I usually hit the red square button to stop the build and before this would work just fine. I have now noticed that the build keeps going (all my CPUs are pegged at 100%). I have to drop to a terminal and do "killall clang" to get them to stop. This happens on both a Mac Pro (2012) and a 2013 MacBook Pro. Both running macOS 10.13.6 and Xcode 10.1. CMake version is 3.13.0 on both machines. > > Has anyone else seen this type of behavior? > > Thanks > -- > Michael Jackson | Owner, President > BlueQuartz Software > [e] mike.jack...@bluequartz.net > [w] www.bluequartz.net > > > > > _______________________________________________ > Qt-creator mailing list > Qt-creator@qt-project.org > https://lists.qt-project.org/listinfo/qt-creator -- Eike Ziller Principal Software Engineer The Qt Company GmbH Rudower Chaussee 13 D-12489 Berlin eike.zil...@qt.io http://qt.io Geschäftsführer: Mika Pälsi, Juha Varelius, Mika Harjuaho Sitz der Gesellschaft: Berlin, Registergericht: Amtsgericht Charlottenburg, HRB 144331 B _______________________________________________ Qt-creator mailing list Qt-creator@qt-project.org https://lists.qt-project.org/listinfo/qt-creator
