PostgreSQL 7.0 can be built on SCO UnixWare 7 and SCO OpenServer 5.

PostgreSQL 7.1 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.

Topics:

*) Skunkware

*) GNU Make

*) C++ and libpq++

*) Readline

*) Using the UDK on OpenServer

*) Compiling PostgreSQL using the UDK

you install the correct version for your operating system, except as noted

below.

***************************************************************************

*) GNU Make

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

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.

OpenServer, you need to specify the locations of the UDK libraries:

configure --with-template=unixware --with-libs=/udk/usr/lib --with-includes=/udk/usr/include

Putting these togetherwith the readline options from above:

Putting these togetherwith the no-C++ and readline options from above:

./configure --with-libs="/udk/usr/lib /usr/local/lib" --with-includes="/udk/usr/include /usr/local/include"

./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

*) Compiling PostgreSQL 7.1 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:

PG_RETURN_INT64(result);

I have not tried using the PostgreSQL man pages on OpenServer. Volunteers??
