Q: Raspberry Pi operating system kills the compiled qt4 executable without any error I'm trying to compile the Elmer FEM software on Raspberry Pi OS (AFIK formerly known as Raspbian). Following these instructions:

*

*sudo apt install cmake gfortran libopenblas-dev libqt4-dev libqwt-dev

*inside the build directory cmake .. -DWITH_OpenMP:BOOLEAN=TRUE -DWITH_MPI:BOOLEAN=FALSE -DWITH_ELMERGUI:BOOLEAN=TRUE

*make -j3

*sudo make install
I managed to compile the software with no errors (... load of warnings though!). Now heading towards /usr/local/bin and running ./ElmerGUI the software icon appears for a minute or two and then disappears with no prompt or errors, showing just a Killed message in the terminal:

               

Given that there is no error messages I have no clue what is going wrong leading to the abrupt termination of the software. I would appreciate if you could help me know what is the problem and how I can resolve it.
My environment:

*

*Hardware: Raspberry Pi 3 Model B Rev 1.2

*Operating system: Linux raspberrypi 5.4.51-v7+ ... armv7l GNU/Linux

P.S. Following this comment on Discord, I did grep -r "Killed" . in the project folder, which returned no results. I'm almost certain the Killed message is from the OS itself.
