cross compiling with linux to create a windows app, cant get libpq to link

[newbie43]

Hi folks
Im using the latest qt and im able to create linux apps and cross compile windows apps on a linux ubuntu system. But now i need my windows app to access a postgresql database that is running on an external linux box. so i added the following to my .pro file

unix:LIBS += -lpq
win32:LIBS += libpqdll.lib

a database connection works ok when compiling for linux but im getting this error when i compile the app for windows.

/usr/lib/gcc/i586-mingw32msvc/4.4.2/../../../../i586-mingw32msvc/bin/ld: cannot find -lpqdll.lib

I know i probably have to download the lib or build the lib from source. Where would i find this library? or do i search for it on the mingw site and just download it and place it in the proper location? Any help would be appreciated. Thanks

Why don't you use Qt's database plugins? You wouldn't need to link against libpq directly.
