1.2)Anything special about the build/install procedure?

When you run configure, you will want to explicitly select either the

hpux_cc or hpux_gcc template depending on which compiler you plan to

use:

./configure --with-template=hpux_cc

If you have both HP's C compiler and GCC's, then you might want to

explicitly select the compiler to use when you run `configure':

CC=cc ./configure

for HP's C compiler, or

./configure --with-template=hpux_gcc

for GNU gcc. (If you omit --with-template, configure may either

default to hpux_cc or give up entirely, depending on which HPUX and

PostgreSQL releases you have.)

You may want to tweak the CFLAGS setting in template/hpux_[g]cc before

you configure. The distributed copy of hpux_cc contains neither -O nor -g

switches, which is hardly optimal for any situation. As of Postgres 6.5,

hpux_gcc sets CFLAGS to -O2, which is fine unless you want to do debugging;

in that case you may want -g as well (or instead).

CC=gcc ./configure

for GCC. If you omit this setting then configure will pick gcc.

The default install target location is /usr/local/pgsql, which

(particularly on HPUX 10) you might want to change to something under

/opt. If so, use the --prefix switch to configure.

If you have both HP and GNU C++ compilers in your PATH, keep an eye on

whether configure picks the right one --- you want the HP c++ if you are

using HP C, or g++ if you are using gcc. Mixing HP and GNU compilers

won't work. You may need to provide a --with-CXX=compiler switch to

force configure to pick the matching C++ compiler, or even say

--without-CXX if you have a C++ compiler but it doesn't match the C

compiler you want to use.

Otherwise the standard build/install procedure described in the

PostgreSQL documentation works fine.

If you want to build the C++ client library (libpq++) then you need

to use a C++ compiler from the same source as the C compiler; mixing

HP and GNU compilers doesn't work. If you have both C++ compilers

in your PATH, keep an eye on whether configure picks the right one.

To override the choice, set the environment variable CXX:

CC=gcc CXX=g++ ./configure

or

CC=cc CXX=aCC ./configure
