Summary: odbc library doesn't work on Solaris

System Configuration
--------------------
Operating System : Sparc Solaris 2.5.1

PostgreSQL version : 6.4.2

Compiler used : gcc-2.8.1

Hardware:
---------
uname -a : SunOS pluton 5.5.1 Generic_103640-24 sun4u sparc SUNW,Ultra-250
Type: SUN E250, RAM: 256 Mo, 8Go disques

Versions of other tools:
------------------------
gmake 3.77, flex 2.5.4, GNUlibstdc++ 2.8.1.1

--------------------------------------------------------------------------

Problem Description:
--------------------
When I want to access base via odbc I've got this message:
ld.so.1: ./iodbc: fatal: relocation error: symbol not found: inet_addr: referenced in /opt/postgres/pgsql/lib/libpsqlodbc.so
This symbol is defined in /usr/lib/libnsl.so
At compile time, configure detect that it must use that library but at runtime, ld.so.1 doesn't load it
I found a command iodbc which display this message, openlink driver manager and
openlink test program doesn't display useful message (e.g.:IM008 !)
I was compiling with gcc2.7.2.3, I switch on 2.8.1 but I've got always the same problem.
Does anyone is using Postgresql on Solaris with odbc support ?

--------------------------------------------------------------------------

Test Case:
----------
iodbc command I use that let system show the real error
is from iodbc-monitor-0.11 downloaded at:
http://www.as220.org/~bjepson/FreeODBC/iodbc-monitor-0.11.tar.gz.
