          Hi k_arnaud,

          I wrote a small tutorial for setting up Qt5.2.1/mingw + PostgreSQL 32-Bit on Win7 - hope it will help:

          1. Prepare compiling of the plugin (Lets assume we install Qt + Sources to C:\Qt, PostgresSQL to C:\Programs(86x)):

          2. Download Qt 5.2.1 32-bit: http://download.qt-project.org/official_releases/qt/5.2/5.2.1/qt-opensource-windows-x86-mingw48_opengl-5.2.1.exe

          3. Run the .exe, install to C:\Qt\Qt5.2.1

          4. Download sources: http://download.qt-project.org/official_releases/qt/5.2/5.2.1/single/qt-everywhere-opensource-src-5.2.1.zip

          5. Extract zip to C:\Qt\Qt5.2.1

          6. Download PostGreSQL 32-bit: http://www.enterprisedb.com/postgresql-932-1-installers-win32?ls=Crossover&type=Crossover

          7. Modify PATH:
            set QTSDK_SQLDRIVERS_PATH=C:\Qt\Qt5.2.1\5.2.1\mingw48_32\plugins\sqldrivers
            set QT_SRC_PATH=C:\Qt\Qt5.2.1\5.2.1\Src\qtbase
            set POSTGRES32=C:\Progra~2\PostgreSQL\9.3 (USE Progra~2 FOR Programs(86x)!)

          8. cd QT_SRC_PATH\src\plugins\sqldrivers\psql

          9. add permanently to PATH (Control Panel): C:\Qt\Qt5.2.1\Tools\mingw48_32\bin

          10. modify C:\Progra~2\PostgreSQL\9.3\include\pthread.h (multiple definitions of struct timespec):
            replace: #ifndef HAVE_STRUCT_TIMESPEC
            with: #if ((!defined(_TIMESPEC_DEFINED)) && (!defined(HAVE_STRUCT_TIMESPEC)))

          11. start building the plugins:
            C:\Qt\Qt5.2.1\5.2.1\mingw48_32\bin\qmake “INCLUDEPATH+=%POSTGRES32%\include” “LIBS+=%POSTGRES32%\lib\libpq.lib” psql.pro
            mingw32-make debug
            mingw32-make release

          12. copy the newly created plugins to C:\Qt\Qt5.2.1\5.2.1\mingw48_32\plugins\sqldrivers:
            copy release\libqsqlpsql.a QTSDK_SQLDRIVERS_PATH
            copy release\qsqlpsql.dll QTSDK_SQLDRIVERS_PATH
            copy debug\libqsqlpsqld.a QTSDK_SQLDRIVERS_PATH
            copy debug\qsqlpsqld.dll QTSDK_SQLDRIVERS_PATH

              Then you can only use this tutorial as a very rough guide as you do not work with the 32-Bit mingw, too.

                Hi Clochydd Clochydd
                i downloaded PostgreSQL 32 bit and i tried to follow what you've written. but i can't undersdands the #7, when you say . " Modify PATH:
                set QTSDK_SQLDRIVERS_PATH=C:\Qt\Qt5.2.0\5.2.1\mingw48_32\plugins\sqldrivers
                set QT_SRC_PATH=C:\Qt\Qt5.2.1\5.2.1\Src\qtbase
                set POSTGRES32=C:\Progra~2\PostgreSQL\9.3 (USE Progra~2 FOR Programs(86x)!)" and more of the following

                when you asked me to run the .exe installed in Qt installed dir, did you mean Qt creator ? if not which .exe i should run ? thanks

                  Hi k_arnaud,
                  sorry, I made a mistake: It should read "Modify environment" as the variables have to be added. You should set these entries in the CMD-window and have a look at the correct paths - relating to your system.

                          If you have installed with msvc2010 you cannot work with the 32-Bit postgres. I never worked with msvc2010.

                                Hi k_arnaud, the message says that the project file for building the plugin cannot be found.
                                Did you go to the plugins directory:
                                8. cd QT_SRC_PATH\src\plugins\sqldrivers\psql
                                If so, does the psql.pro exist here?

                                    You should check your pathnames again - it seems that dependencies cannot be found. If you cannot find a fault: What is the unreadable message?

                                        Hi k_arnaud, with "set QTSDK_SQLDRIVERS_PATH=C:\Qt\Qt5.2.0\5.2.1\mingw48_32\plugins\sqldrivers" you create the environment-variable QTSDK_SQLDRIVERS_PATH, which you need later (#12.). Where appropriate you must modify the path itself - according to your system.
                                        These variables are for your comfort - you may use the complete pathname instead.

                                          that is what i did, i entered QTSDK_SQLDRIVERS_PATH=C:\Qt\Qt5.2.0\5.2.1\mingw48_32\plugins\sqldrivers in the CMD-windows without any change
