Starting /home/geng/Documents/build-SolarSystem-Desktop-Debug/SolarSystem...
The program has unexpectedly finished.
The process was ended forcefully.
/home/geng/Documents/build-SolarSystem-Desktop-Debug/SolarSystem crashed.

I just developed the program on MacOS and now transfer it to Ubuntu 18.04. After everything is set, there is no error but the program always unexpectedly finished. Could you help me figure out this? I have attached the .pro file. Thank you!

The best approach would be to compile with debug option and start the debugger. There you will see if you can reach the first statements or if it is already during startup.

Thank you, I have tried and fixed that. This is caused by null pointer. Though I still don't know why the function works well on MacOS.

It's just a coincidence. Even though it seems to work at first, it can crash in the future.
