Troubles with the ODBC driver in the postgres distribution (integrated installation)

(Sparc Ultra10, solaris 2.6, Postgres 6.4.2)

Hello everybody, can you help me?

I 've tried to install the ODBC driver like the description
in "PostgreSQL Programmer's Guide" guide (153-157).
I've tried the integrated installation and also the standalone
installation.

What is the compiler needed for C++? I have tried a GNU one and a
Solaris one?
What is the good version for GNU C++?

-----------------------------------------------
My compilations for integrated installation:

1> integrated installation with a GNU c++
 ./configure --prefix=/export/sgbd/pgsql
--with-template=solaris_sparc_cc --with-odbc
--with-CXX=/usr/local/bin/c++

gmake

How can I fix the problem?
What is the mistake?

thank you for answering :)
