Cannot build PostgreSQL driver

[DanMcCoder]

After several attempts I was able to solve the problem.
The problem was that my environment variables INCLUDE and LIB were not set.
In order to build the entire Qt library or just a part of it (like my case building QPSQL plugin)
besides extending the "path" variable it is also necessary to set the "include" and "lib" variables with the right paths.
If those two variables are not present, they need to be created.
Here is how I have set my variables:

Created the following new variables:
QTDIR=C:\Qt\4.6.3
MINGW=C:\mingw

Extended "path" variable adding the following paths:
%QTDIR%\bin
%MINGW%\bin

Created "lib" variable with the following paths
%QTDIR%\lib
%MINGW%\lib

Created "include" variable with the following paths
%QTDIR%\include
%MINGW%\include

Please notice I am compiling with MinGW on WINXP, I don't know about other platforms but I imagine it will be somewhat similar.

I hope this will help anybody else having a similar problem.

QtCreator 2010.04, QT 4.6.3, GCC 4.4, OS 7

I find out that compiling plugin with libraries from postgressql 8.4 fail, but with version 8.3 works as described on wiki.
