I am a little bit (ok, way) over my head here,  but I have a 32bit linux
binary that crashes on my amd64 system. If that isn't convoluted enough, it
is also running in a jail. Specifically, if anyone cares, it seems to be the
source metamod 3rd party add-on to valve software's source dedicated server.
I have provided the developer(s) of the mod a jailed test environment to
debug in with linux_base-fc4, but they are asking how to enable linux
debugging compatibility, but I have no idea how to do so, and my googling
attempts have only turned up old references to /usr/ports/devel/linux_devel
which doesn't seem to exist any more.

Here is exactly what he asked me:

>I haven't used FreeBSD since 4.4 or so.  I've installed gdb66 and
i386-rtems-gdb
>(whatever that is) in vain attempts to get Linux debugging compatibility
but to

If you really want, you can view all the gory details here:

but my basic question is, what is the answer to his question of how to get
linux debugging compatibility?
