Обсуждение: Problem compiling on HP/Compaq Tru64 UNIX

We are trying to compile and install postgresql on Tru64 UNIX. We get some
errors during the build saying NAN not defined.

Is there something we need to modify to correct this or a compile time
option we need to change? Any help/advice is appreciated.

AFAICS, all uses of NAN in the PG code are preceded by something like

#ifndef NAN
#define NAN        (0.0/0.0)
#endif

... which might or might not be the right thing for your platform, but
it certainly shouldn't yield an "undefined name" kind of error.

Could you be more specific about what error you're getting?
And where?

And mention the PostgreSQL version.

After some further investigation it turns out to be a Compaq problem, the
compiler doesn't default to IEEE floating point. Once the
-ieee was added to the compiler switches in the makefile everything built
fine.
