[gentoo-user] How do I get a core dump from seg-faulting software?

[Alan Mackenzie]

Hello, Gentoo.

I'm developing software, and it crashes in its build process.  I want a
core dump, to help find out where and why it's crashing.

I've got CONFIG_ELF_CORE and CONFIG_COREDUMP both configured to yes in
my kernel.

When I do

    $ uclimit -H -c

, it tells me "unlimited".

But still, no dump.  :-(

What am I missing?
