How to get a core dump?

[dspence]

How do I get Tiny Core to generate a core dump file when something crashes?
Where would I find the core dump?

Hi dspence
You need to use  ulimit  to set the allowable size for a core dump file:

Code: [Select]

ulimit -c unlimited
By default it is set to zero which means the kernel will not write a core dump file:

Code: [Select]

tc@E310:~$ ulimit -a
-f: file size (blocks)             unlimited
-t: cpu time (seconds)             unlimited
-d: data seg size (kb)             unlimited
-s: stack size (kb)                8192
-c: core file size (blocks)        0
-m: resident set size (kb)         unlimited
-l: locked memory (kb)             64
-p: processes                      24156
-n: file descriptors               1024
-v: address space (kb)             unlimited
-w: locks                          unlimited
-e: scheduling priority            0
-r: real-time priority             0
tc@E310:~$
The core dump should show up in the directory you used to run the file.

Thank you, Rich!  Sorry I didn't get back after asking the question.

This worked for me for Tiny Core 13 but I'm now having trouble with getting truncated files with 17.  I guess I will start a new topic.
