Apollo Autonomous Driving Development Notes 46 - Generation and debugging of apollo coredump

First level directory

Most systems have the core dump function turned off by default and need to be turned on again.

1. Check if core dump is open

Press the shortcut key "Ctrl+Alt+T" to open the command terminal and enter the command:

ulimit -c

If the output result is 0, it means that the core dump function is turned off by default, that is, when the program terminates abnormally, no core dump file will be generated.

2. Open the core dump in the current command terminal

Use command:

ulimit -c unlimited

The core dump function of the current command terminal can be turned on without limiting the size of the core dump file; if you need to limit the file size, modify unlimited.
