2.0 isn't self-building

Hi,

Trying to self-build with a new netbsd-2 source branch doesn't work:

GROFF_COMMAND_PREFIX='';  export GROFF_COMMAND_PREFIX; 
GROFF_BIN_PATH=`echo /home/obj/tools/groff/build/src/roff/groff

Any ideas?

I've just installed 2.0 on a 4000-500, and got lots of weird errors
("illegal instruction" from temacs when building Emacs, "internal
error" from gawk when building something else, "system error" from
something I don't recall, gunzip claimed checksum failures in known
good archives...), so I've now installed a cross-compiled -current.

The problems were repeatable, so probably (hopefully!) not hardware.

I'll post more as I experiment with -current.

To continue building, I copied over the released pic and continued.  The
next issue is grn:

Sorry -- didn't mean to send that just yet...  I see there's some
unfinished code involved.  I'll dig a bit further.

OK, *that* is an overstatement.  I can use Emacs, and I do, but it's
incredibly easy to crash it: anything that explicitly changes input
focus to the minibuffer will, for instance, cause it to go down in
flames immediately.  ("M-x", for instance, or "C-f".)

Re: 2.0 isn't self-building

Hi,

i have similar problems on my VS4000/60.
While i'm not expierienced with Make

filesyntax, in src/lib/libm/Makefile there is one thing that seems odd to me:

.elif (${MACHINE_ARCH} == "vax")
#.PATH: ${.CURDIR}/arch/vax
#NOIEEE_ARCH= n_infnan.S n_argred.S n_sqrt.S
#ARCH_SRCS = n_atan2.S n_cabs.S n_cbrt.S n_support.S n_sincos.S n_tan.S
# XXX - ripped out due to lack of the insn polyd in the Mariah chip,
# and emulation code isn't written yet.
WARNS?=2
.endif

Above the n_atan2.S is ripped out, but...

.if (${MACHINE_ARCH} == "vax") # XXX until POLYD is written.
.PATH:  ${.CURDIR}/arch/vax
SRCS:=${SRCS} n_sqrt.S n_argred.S n_infnan.S n_atan2.S n_cabs.S n_cbrt.S \
        n_support.S

Here it is included. Maybe this is the source of the problems.

That should be "C-xC-f", of course.

...and it works fine.

All in all, it looks to me as if -current on VAX works perfectly, with
the single exception that libm uses the "polyd" instruction, which
isn't supported on my VAX, a KA680 (in a 4000-500).  I suspect this
means that applications that use that instruction will fail on quite
a few different models of VAXen, right?

The Makefile also includes some magic that causes it to use the .S
source even if you explicitly specify that you want the .c from the
noieee directory -- and the .c doesn't compile properly anyway,
because of multiple warnings generated by the compiler.  I haven't
gotten around to working this out yet, but I'll give it a try.
