ppc Linux-2.4.2 not generating core dump for SIGSEGV and abort()

ppc Linux-2.4.2 not generating core dump for SIGSEGV and abort()

[mdaljeet]

Hi all,
     I am using Suse-linux-7.1 with default linux -ppc kernel on apple G4
machine.
SIGSEGV is never generating the core dump. though this signal is being
caught by the user process.
I also tried with "abort" call which should generate the core dump, but
this is also not working. The same program with abort call is generating
core dumps on other linux/unix platforms.
Can anybody tell me where is the problem?

Daljeet.

Hi,

you should probably check your limits. Try

ulimit -a

you'll probably have a coresize of 0 (SuSE's default I believe)
change it with

ulimit -c unlimited

(or some number, see also man ulimit).

This might help.

Ronald

    Core dumps are disabled by default for a SuSE install.

    If you're using bash:
    ulimit -c unlimited

    or csh:
    unlimit coredumpsize

What does 'ulimit -a' print ?
