Yup; that is the error message that accompanies awk's termination (from
within the src/usr.bin/kdump/mkioctls script) with status 2.

By breaking down the parts of the pipeline in src/usr.bin/kdump/mkioctls,
it looks as if the problem is that the (shell) variable ioctl_includes
is being set to a list of #include directives, one per line, such as:
#include <cam/scsi/scsi_pass.h>
#include <cam/scsi/scsi_ses.h>
#include <cam/scsi/scsi_targetio.h>
#include <dev/ppbus/lptio.h>
#include <dev/ppbus/ppi.h>
...
That shell variable is being used to set the value of a similarly-named
awk variable:
awk -v ioctl_includes="$ioctl_includes" -v use_switch="$use_switch" '
And awk does *not* seem to like having embedded newline characters in
there.
By generating the output to a separate file, the replacing each "real
newline" with a C/awk/Perl representation thereof (i.e., "\n"), I was
able to get the awk part of the pipeline to terminate with a status of
0, while generating what looks like reasonable output (though I'm hardly
an expert on that).
If there is a way to tell awk to "quit whining and *like* the newlines",
that would seem to be ideal. Failing that, I can work up some way to
transmogrify the #include list so awk will like it better....
Am I really the only one who has seen this?
Cheers,
david
