How to generate core dumps in Mac OS X?

Question

It seems like I can not generate core dumps in Mac OS X 10.6.8.

$ ulimit -c unlimited
$ ./a.out 
Hello world!
Segmentation fault
$ find ~/ -type f -name core         


        

Answer 1

You can generate core dump files on Mac Os X like this:

1. Create the file : /etc/launchd.conf, then :

   echo "limit core unlimited" | sudo tee -a /etc/launchd.conf

2. Restart your Mac.

And that's it, the core dump files are generated in the /cores directory. Be careful the core dump files are large files so when you finishing troubleshooting your code, remove them.
