Sorry I cannot find your reply in email archive. Looking at this
error, the root cause should be strtonum requires gawk while what we
installed is

        mawk 1.3.3 Nov 1996, Copyright (C) Michael D. Brennan

We can trivially install gawk and make it the default, however is gawk
a requirement for kernel compilation? Or can we make it work with mawk,
too?

Well gawk/mawk both defined int(), however it behaves different:

wfg ~% mawk 'BEGIN{print int("0xff")}'
255
wfg ~% gawk 'BEGIN{print int("0xff")}'
0
wfg ~% gawk 'BEGIN{print strtonum("0xff")}'
255

Thanks,
Fengguang

Odd, because I sent a reply to your report on 29th September, and it
made it to the linux-arm-kernel mailing list, and its archives:

Well, awk isn't mentioned in Documentation/Changes as a build requirement,
but then neither is grep.  However, kbuild itself makes use of both:

Makefile:AWK                = awk
Makefile:   $(Q)$(AWK) '!x[$$0]++' $(vmlinux-dirs:%=$(objtree)/%/modules.order) > $(objtree)/modules.order
Makefile:   $(Q)$(AWK) '!x[$$0]++' $^ > $(objtree)/modules.builtin
scripts/Makefile.build:     if $(OBJDUMP) -h $(@D)/.tmp_$(@F) | grep -q __ksymtab; then                \

So I don't think awk can be used reliably for this - there seems to be
no reliable way to convert hex to an integer in awk.

Maybe the easiest solution would be to switch to using perl instead -
at least perl is listed as a required tool, and perl's hex() function
will always be able to parse hex!

Ah yes, I find that now. So I'm using mawk, which does not support
gawk's strtonum..

Right. Here gawk/mawk happen to behave different on int(), which makes
awk not usable here in a portable way. As you said in the other email,
perl looks a viable alternative.

Thanks,
