PostgreSQL trouble Windows Platform

Message 1 in thread

Hi!
I'm running QT-4.2.2 on WindowsXP Pro.
After reading
http://doc.trolltech.com/4.2/sql-driver.html#how-to-build-the-plugin-on-windows

I've succesfully built libqsqlpsql.a and qsqlpsql.dll.
I've moved those files into my database project root-dir.
But after running project executable, I has an error "Driver not loaded".

Can I fix this issue?

P.S. QT-4.2.3 under Windows was deployed without PostgreSQL support, so
I've built only psql driver ( as described in previous e-mail )

Under my Linux Developers Machine project works perfectly.

Read Qt docs about "Deploying an Application on Qt/Windows", check 
qsqlpsql.dll dependencies with depends, copy qsqlpsql.dll into "project 
root-dir/plugins/sqldrivers" and delete registry key
HKEY_CURRENT_USER\Software\Trolltech\OrganizationDefaults.

Well, there is nothing about how-to show to configure where Postgre
include/ and lib/ paths are located.

E.g. I run (WINDOWS)
configure -qt-sql-psql -platform windows-g++

Do I need to pass to configure Postgre Developers library paths and how to
do this? ( they are installed into c:\psql\include and c:\psql\lib )

you already siccesfully build qsqlpsql, or i missing something ?

Here how i do it (MVS, sorry):

build Qt:

configure -fast -debug-and-release
nmake

then build psql plugin:

cd to %QTDIR%/src/plugins/sqldrivers/psql/
qmake -makefile "INCLUDEPATH+=D:\PostgreSQL\include" 
"LIBS+=D:\PostgreSQL\lib\ms\libpq.lib"
nmake

Then delete registry key 
HKEY_CURRENT_USER\Software\Trolltech\OrganizationDefaults


Now if you run %QTDIR%\demos\sqlbrowser you should see QPSQL available 
in drivers combo.
