Useful things for coredumps on linux

Where are the coredumps generated?

$ cat /proc/sys/kernel/core_pattern


Before running your executable, set the limit for the coredump:

$ ulimit -c unlimited

You can add ulimit -n 99999 in your ~/.bashrc. But if you want all gui apps(qtcreator) to use it, you should also include it in your ~/.xsession:


ulimit -n 99999

You mai also need to update the limits(only if setting the limit returns error):

sudo nano /etc/security/limits.conf

* hard nofile 99999

# --------------------

sudo nano /etc/pam.d/common-session

session required
