postgresql/doc/FAQ_SCO
Bruce Momjian e134556743 I have compiled and tested PostgreSQL 7.1devel on UnixWare 7.1. During the 
process, the need for changes to the FAQ_SCO document was uncovered.  The
attach patch file implements thost changes.

Frequently Asked Questions (FAQ) for PostgreSQL V7.0
SCO UnixWare and OpenServer Specific
TO BE READ IN CONJUNCTION WITH THE NORMAL FAQ
=======================================================

PostgreSQL 7.0 can be built on SCO UnixWare 7 and SCO OpenServer 5.
On OpenServer, you can use either the OpenServer Development Kit or
the Universal Development Kit.
However, some tweaking may be needed, as described below.
Topics:
*) Skunkware
*) GNU Make
*) C++ and libpq++
*) Readline
*) Using the UDK on OpenServer
*) Compiling PostgreSQL using the UDK
*) Reading the PostgreSQL man pages on UnixWare
***************************************************************************
*) Skunkware
You should locate your copy of the SCO Skunkware CD. The Skunkware CD is
included with UnixWare 7 and current versions of OpenServer 5.
Skunkware includes ready-to-install versions of many popular programs that
are available on the Internet. For example, gzip, gunzip, GNU make, flex,
and bison are all included.
If you do not have this CD, the software on it is available via anonymous
ftp from ftp.sco.com/skunkware.
For UnixWare 7.1, this CD is now labeled "Open License Software Supplement".
Skunkware has different versions for UnixWare and OpenServer. Make sure
you install the correct version for your operating system, except as noted
below.
***************************************************************************
*) GNU Make
You need to use the GNU make program, which is on the Skunkware CD. By
default, it installs as /usr/local/bin/make. To avoid confusion with the
SCO make program, you may want to rename GNU make to gmake.
***************************************************************************
*) C++ and libpq++
I have not been able to build libpq++, the PostgreSQL C++ interface, with
the UnixWare or OpenServer C++ compilers. By default, building PostgreSQL
also builds the libpq++ interface. When that fails, it causes the entire
build of PostgreSQL to fail.
This is the problem if you see the following error message:
"pgenv.cc", line 47: error: no default constructor exists for class "string"
If you have this problem, you can disable building of libpq++ with the
following configure option:
configure --without-CXX
***************************************************************************
*) Readline
If you install the readline library, then psql (the PostgreSQL command line
SQL interpreter) remembers each command you type, and allows you to use
arrow keys to recall and edit previous commands. This is very helpful, and
is strongly recommended. The readline library is on the Skunkware CD.
The readline library is not included on the UnixWare 7.1 Skunkware CD. If
you have the UnixWare 7.0.0 or 7.0.1 Skunkware CDs, you can install it from
there. Otherwise, try ftp.sco.com/skunkware.
By default, readline installs into /usr/local/lib and /usr/local/include.
However, the PostgreSQL configure program will not find it there without
help. If you installed readline, then use the following options to
configure:
configure --with-libs=/usr/local/lib --with-includes=/usr/local/include
Putting this together with the no-C++ option above yields:
configure --with-libs=/usr/local/lib --with-includes=/usr/local/include --without-CXX
***************************************************************************
*) Using the UDK on OpenServer
If you are using the new Universal Development Kit (UDK) compiler on
OpenServer, you need to use different arguments to the configure program.
First, you need to specify the "unixware" template instead of the default.
Second, you need to specify the locations of the UDK libraries.
Putting these together:
configure --with-template=unixware --with-libs=/udk/usr/lib --with-includes=/udk/usr/include
Putting these together with the no-C++ and readline options from above:
./configure --with-template=unixware --with-libs="/udk/usr/lib /usr/local/lib" --with-includes="/udk/usr/include /usr/local/include" --without-CXX
***************************************************************************
*) Compiling PostgreSQL 7.0 with the UDK
The program, backend/utils/adt/int8.c, tickles a compiler bug with in the
following versions (and probably others as well) of the C compiler:
Optimizing C Compilation System (CCS) 3.2 08/18/98
Optimizing C Compilation System (CCS) 3.2 09/28/99
If you encounter an error compiling backend/utils/adt/int8.c, please apply
the following patch:

The bind function in UnixWare 7.1+ has a problem when used with the AF_UNIX
family. The following patch provides a work-around for the problem (thanks
go to Oliver PRENANT <ohp@pyrenet.fre> for this patch).

***************************************************************************
*) Reading the PostgreSQL man pages on UnixWare
By default, the PostgreSQL man pages are installed into /usr/local/pgsql/man.
By default, UnixWare does not look there for man pages, so you will not be
able to read them.
You need to make the following changes to access the PostgreSQL man pages
from UnixWare.
1) You need to modify the MANPATH variable in /etc/default/man. I use:
MANPATH=/usr/lib/scohelp/%L/man:/usr/dt/man:/usr/man:/usr/share/man:scohelp:/usr/local/man:/usr/local/pgsql/man
2) Add a line that says '1sql' to /etc/default/manSection.
3) The man pages for SQL commands are, by default, placed in section 'l'
(normally used for "l"ocal pages). UnixWare does not support the 'l'
section.
The solution I use is to move all these pages from section 'l' to a section
named '1sql'. To following KSH script will perform the move and change the
section names in the man page:
------------------------------8< CUT HERE >8------------------------------
#!/bin/ksh
cd /usr/local/pgsql/man
mv man1 man.1
mkdir man.1sql
cd /usr/local/pgsql/man/manl
for i in *.l
do
sed -e '/^\.TH/s/"l"/"1sql"/' \
-e 's/\\fR(l)/\\fR(1sql)/' $i >../man.1sql/${i%.l}.1sql
done
cd /usr/local/pgsql/man
rm -rf manl
/usr/ucb/catman -M /usr/local/pgsql/man 1
/usr/ucb/catman -M /usr/local/pgsql/man 1sql
------------------------------8< CUT HERE >8------------------------------
After running this script, you can view the man pages using the 'man'
command. They will not be usable from the scohelp system.
I am working on integrating the man pages into the scohelp system. When I
generate a PostgreSQL package for UnixWare 7.x, the man pages will be
integrated into the scohelp system.
I have not tried using the PostgreSQL man pages on OpenServer. Volunteers??
