generating core dumps

generating core dumps

[Inderjeet Saggu]

Hi,

	I searched your web site for the answer to this silly question without
success.

	I am using GCC for C code application. First application is starting the
2nd application using fork() and execl(). The 2nd application crashes with
"No core dump". How do I make the 2nd application crash with core dump which
I can examine under the ddd.

	I have been searching under the compiler options and found nothing. Your
guidance would be appreciated.

Thanks
saggu

That's because the compiler has nothing to do with it.  :-)

Whether a process can generate a core dump is controlled by resource limits.
The commands to examine and change resource limits depend on what shell
you use; for sh-family, use "ulimit", and for csh-family, use "limit".

For more information, read the man page for your shell, or ask your system
administrator.  Many sysadmins turn off core dumps to save on diskspace,
because many users don't know what they are and forget to delete them.
