Yes...

There are a number of minor porting problems with 6.3.2 on HPUX;
see my message in the pgsql-patches archives for 21 Apr 1998. All
except one item have been addressed in the current development sources.
The "one item" is that configure doesn't know about having to look
in /lib/pa1.1 to find rint() on HPUX 9. I've been debating whether
it's worth the trouble to fix that or not, vs. just putting a note
in the INSTALL directions to manually correct the config.h file.

Is this something we can just ptu a check for tha tlibrary into
the configure script and all will be well?

In other words, Just Do It, eh? I suppose you're right.
The attached does the right thing on HPUX 9 and looks fairly harmless
for other platforms.

Applied. I see it is needed by configure so it finds rint on hpux. I assume you have looked at makefiles/Makefile.hpux. > The Hermit Hacker <scrappy@hub.org> writes: > >> The "one item" is that configure doesn't know about having to look > >> in /lib/pa1.1 to find rint() on HPUX 9.

What is rint? I just checked HP-UX 9.0 running on my 360 and it's not
there. Is it a special thing for PA?

DESCRIPTION
The rint() and the rintf() functions return the integral value
(repre-sented as a double or float precision number) nearest to x
according to the prevailing rounding mode.

Yes, the HPUX makefile was fixed some time ago. The last piece of the
puzzle was to teach configure about it.

rint() didn't use to be a standard part of libm, but I think it's
mandated by recent versions of the IEEE float math spec. In HPUX 10,
it's part of the standard math library libm. In HPUX 9, it's not in
the standard libm but is in the PA1.1-only libm that's kept in
/lib/pa1.1. The patches we're talking about have to do with configuring
Postgres to use that math library so it can use the native version of
rint().
I have no idea whether rint() is available anywhere for Series 300
machines. You don't have to worry too much if not; there is a
substitute routine available in the Postgres distribution.
BTW, does anyone have access to HPUX 9 running on a PA1.0 processor, ie
an old Series 800 machine? Is the /lib/pa1.1 directory even present in
such an installation? It suddenly occurs to me that we may need a
smarter approach to dealing with /lib/pa1.1, if that directory could be
present on machines that can't use the code in it. The current setup
in configure and Makefile.hpux will do the right thing if /lib/pa1.1
is not there at all, but if it is there on a 1.0 machine then you'd
end up with an unusable executable...
