Building DBD::ODBC on Windows
=============================

Quick hints:

1. Make sure when you run "perl Makefile.PL" that you specify which
   make you are using (dmake, nmake). You do this with:

   perl Makefile.PL MAKE=nmake

   If you don't, ExtUtils::MakeMaker will generate the Makefile for
   the default make which may not be the one you are going to use and
   this will lead to make errors.

2. I've had a number of reports that attempting to build with Borland's
   make does not work. If that happens to you please don't tell me; get
   nmake or dmake.

3. If you are not interested in Unicode support disable it as Unicode
   support is built in by default on Windows builds. You can disable it
   with -nou as in:

   perl Makefile.PL -nou

4. If you are building DBD::ODBC for use with ActiveState Perl then
   good luck. I have never managed to build DBD::ODBC in such a way
   that it works with ActiveState Perl and had to resort to building
   Perl for Windows from scratch then building DBD::ODBC. This is
   something to do with the fact that you need the exact same compiler
   ActiveState uses.

   If you have reliable information on how to do this I would like to
   know.

64bit Windows
=============

I have built DBD::ODBC on win64 and the tests to SQL Server completed
successfully. However, you will need at least version 1.15 if you want
to run DBD::ODBC on win64 successfully.

If you are running a 32bit Perl on a 64bit Windows machine you will
need to be aware there are two ODBC administrators and you need to
create your DSNs with the right one. The ODBC Administrator you get to
from Control Panel, Administrative Tools, Data Sources is the 64bit
one and data sources created here will not be visible or useable from
32bit applications. The ODBC administrator you need to use for 32bit
applications can be found at X:\windows\syswow64\odbcad32.exe.
