cd ../examples/network/ftp

qmake -project
qmake
gmake

i get error:

ftpwindow.cpp:25:21: QtNetwork: No such file or directory
ftpwindow.cpp: In member function `void FtpWindow::connectOrDisconnect()':
ftpwindow.cpp:88: invalid use of undefined type `struct QFtp'

How to resolve the problem?

With "qmake -project" you have overwritten the original .pro file. Now you have to add "QT += network" to the new .pro file to make it work.

configure -plugin-sql-psql -I " D:\PROGRAM FILES\postgres\include -L D:\PROGRAM FILES\postgres\lib"

Copy PostgreSQL files (headers and libraries) to some other directory, so that the path doesn't contain spaces.
