Linux Cordeumps
===============
So that the unit testing framework can autorun gdb it needs to reliably find the corefiles.
In Linux this is configured via the `/proc` filesystem, you can make this reboot permanent by
creating the file `/etc/sysctl.d/corepattern.conf` (or add the following lines to `/etc/sysctl.conf`)
# We want core files to be located in a central location
# and know the PID plus the process name for later use.
kernel.core_uses_pid = 1
kernel.core_pattern = /var/tmp/core-%e-%p-%t
Note that the `proc` paths translate sub-directories to dots. The non permanent way of doing this in a running system is:
echo 1 > /proc/sys/kernel/core_uses_pid
echo '/var/tmp/core-%e-%p-%t' > /proc/sys/kernel/core_pattern
Solaris Coredumps
=================
Solaris configures the system corefile behaviour via the `coreadm` programm.
see https://docs.oracle.com/cd/E19455-01/805-7229/6j6q8svhr/ for more details.
Windows debugging
=================
For the average \*nix user windows debugging has some awkward methods.
