Hi,

I suppose it is getting a bit late for this, now that postgreSQL 7.0 is in beta,
but I have finally gotten all the patches together to make postgreSQL 6.5.3
compile completely on an SGI Irix 6.5. This includes all the interfaces: JDBC,
ODBC,  libpq++, tcl, pgaccess, PL/pgsql, etc.  As it turns out, all the patches
are minor.

So, here is my patch list:
============================================================================
Patch for PostgreSQL 6.5.3 on SGI Irix 6.5.
Submitted by Mark Dalphin, March 1, 2000.

Generated by:
  diff -c -r postgresql-6.5.3/ postgresql-6.5.3.patched/ > irix_6.5.patch

======================================================================
Discussion of PostgreSQL and its interfaces

These patches are relatively minor in the overall source tree, but
permit everything to compile, including libpq++, odbc, PL/pgsql, and
tcl.

There are no errors while running the regression tests except for
error message words and some date problems in 1947.

I can compile and run the libpq++ examples:
        cd .../src/interfaces/libpq++
        gmake examples
        cd examples
        ./testlibpq ...
I have not tested this material carefully, however.

I have not tested the tcl interface, however, pgaccess, which uses it,
runs well.

I use the perl DBI::DBD on a daily basis without any trouble. The
libpq C library is used by these modules and, furthermore, I use it
directly as well without any troubles.

The ODBC library has been tested a little using the Data Access Builder
from IBM's Visual Age for Java. It worked without any trouble after we
got things configured at the PC end. No configuration was needed at the
Irix end of the connection.

The build of the JDBC code caused some trouble since it assumes the
use of the GNU bash shell. I ended up building it following the commands
in the Makefile, but was unable to get the automated build to work.
After the JDBC interface was built, it has worked well for Java 1.1.6.

The system is compiled with the native C compiler (/usr/bin/cc;
MIPSpro Compilers: Version 7.30; /etc/compiler.defaults =
-DEFAULT:abi=n32:isa=mips4:proc=r10k) and the native C++ compiler
(/usr/bin/CC).

Other packages installed include:
        flex version 2.5.4
        GNU Bison version 1.25
        GNU Make version 3.76.1
        install (GNU fileutils) 4.0
        GNU lib readline, ver 4.0
        tcl 8.0, tk 8.0 (this is a local install, not the SGI Freeware)
        perl 5.005_03

The configure command is:

./configure \
        --with-CC=/usr/bin/cc \
        --with-CXX=/usr/bin/CC \
        --prefix=/usr/local/pgsql \
        --with-includes=/usr/local/include \
        --with-libraries=/usr/local/lib \
        --with-tcl \
        --with-tclconfig=/usr/local/lib \
        --with-tkconfig=/usr/local/lib \
        --with-perl \
        --with-odbc

A description of the function of each patch is listed just above the patch.
======================================================================

This patch makes it so that PostgreSQL can "find" the DSO (shared
libraries) without using the environment variable, LD_LIBRARY_PATH.

======================================================================

This patch alters the Makefile options, removing GNU gcc options which
choke the SGI C++ compiler. It is only a problem on the examples for
libpq++.

The next several patches all "repair" the same problem. The re-declaration
of the variable 'i' as an 'int' in the second of two 'for' loops, causes
an error for the SGI C++ compiler. It complains that 'i' is already in
scope. This is only a problem in the example code.

The next two patches add support for a new C++ concept, 'namespaces',
to libpq++.  The SGI C++ compiler uses namespaces by default and,
while there is a way to turn off support for namespaces (option:
-LANG:namespaces=OFF) this seems to mess up support for the Standard
Template Library. It was easier to add the 'use namespaces std;' line
to the libpq++ include files.

The odbc interface would not compile "out of the box" simply because
the libraries were not correctly specified when linking. While the
names of the libraries were listed, eg -lpq -lreadline, etc, the
additional library locations, eg -L/usr/local/lib, had been lost.
This change fixes that problem, though I am not certain that I have
followed the correct PostgreSQL Makefile conventions here...

This patch is for convienence. I hate the large number of error
messages which appear when PostgreSQL is built. This patch turns off
certain common error messages.  Note, this only applies to the SGI cc
compiler when using the -n32 switch; the error message numbers change
for the -o32 (aka -32) switch.
