Thread: C++ - libpq-fe.h and QT

I use Kdevelop on a red Hat 6.2,

              -> libpq-fe.h is in /usr/include/pgsql
              -> qt lib is in /usr/lib/qt-1.45

              I made a program that uses a QTableView, works fine,
              I made another program that uses a terminal window and conects to postgresql and works fine. But I tryied
tomake a third 
              program that uses both libs and does not work.
              did not find the QTableView.h .

              how to make both libs to work ???

              Thanks,
              Eduardo K
