Hi Everybody,

I am trying to build the QPSQL driver plugin on Windows using MinGW.
I have followed the instruction at this link:
http://www.qtcentre.org/wiki/index.p...ws_using_MinGW
but unfortunately with no success.

I have generated libpq.a file using reimp and dlltool
and I have run the following qmake command:
Qt Code: 
  1. qmake -o Makefile "INCLUDEPATH+=C:\Programmi\PostgreSQL\8.4\include" "LIBS+=C:\Programmi\PostgreSQL\8.4\lib\libpq.a" psql.pro
To copy to clipboard, switch view to plain text mode 
When I run mingw32-make I get the following output:

Qt Code:

The libqsqlpsqld4.a is generated but there is no dll.
I went through these steps several times but I cannot figure out how to solve this problem. I have also followed the instructions at this link where they seem to have the same problem:
http://www.qtcentre.org/threads/1899...Database/page2 but it didn't work.
This is my configuration: WINXP SP2 / QT 4.6.3 (qt-sdk-win-opensource-2010.04) / PostgreSQL 8.4

Does anybody know how to solve this issue? Is there any other way to get this driver?
Thank you very much for your help

Regards
Daniel
