i have been trying to build the Qt Driver for 2 weeks now , without succeed. I even moven on windows xp 32 Bit to avoid compatibility Problem with the 64 bit (which i faced when trying to link Psql libraries to my C Program). Using a normal C compiler does function but when i want to have a GUI. I tried qmake -o Makefile "INCLUDEPATH+=D:/Programme/PostgresSQL/9.0/include" "LIBS+=D:/Programme/PostgresPlus/9.0/lib(or /lib/libpq.lib)" psql.pro it generates Makefile debug and release Now when i try : mingw32-make debug or release or even just mingw32-make
D:\Qt\2010.05\qt\src\plugins\sqldrivers\psql>mingw32-make
mingw32-make -f Makefile.Debug all

I really have no idea what this missing -lpq might be. Thanks for Helping. Mehdi
