      I compiled qftp into a shared library and linked the main application to the library.

      this is the .pro file for qftp
      @load(qt_build_config)
      Template = lib
      TARGET = QtFtp
      CONFIG += shared
      CONFIG -= create_prl
      QT = core network
      CONFIG += no_install_prl
      MODULE_PRI = ../../modules/qt_ftp.pri
      MODULE = ftp

      load(qt_module)

      Input

      HEADERS += qftp.h qurlinfo.h
      SOURCES += qftp.cpp qurlinfo.cpp
      @

            Could you point me step by step how to do this.
            I am a beginner programmer QT.

            I copy qftp.h and qurlinfo.h to ftp example project,
            and
            add to qftp.pro
            line HEADERS += qftp.h qurlinfo.h

            but when i run project i have many errors like:

            C:\Qt\5.1.1\5.1.1\msvc2010_opengl\examples\network\build-qftp-Desktop_Qt_5_1_1_MSVC2010_32bit_OpenGL-Debug\debug\moc_qftp.cpp:125: błąd:C2027: use of undefined type
            'QFtpPrivate'
            c:\qt\5.1.1\5.1.1\msvc2010_opengl\examples\network\qftp\qftp.h:51: see declaration of 'QFtpPrivate'
            ...

            first error go to
            case 9: _t->d->_q_startNextCommand(); break;

                1. build source qt-qtftp
                  qmake /Src/qt-qtftp/src/src.pro
                  nmake
                  nmake install

                after
                change in qt-qtftp/src/qftp/qftp.pro

                @ CONFIG -= static
                CONFIG += shared@

                and compile again

                in lib a have now
                c:\Qt\5.1.1\5.1.1\msvc2010_opengl\lib\Qt5Ftp.dll
                c:\Qt\5.1.1\5.1.1\msvc2010_opengl\lib\Qt5Ftpd.dll
                c:\Qt\5.1.1\5.1.1\msvc2010_opengl\lib\Qt5Ftp.lib
                c:\Qt\5.1.1\5.1.1\msvc2010_opengl\lib\Qt5Ftpd.lib
                c:\Qt\5.1.1\5.1.1\msvc2010_opengl\lib\Qt5Ftpd.pdb
                c:\Qt\5.1.1\5.1.1\msvc2010_opengl\lib\Qt5Ftp.prl
                c:\Qt\5.1.1\5.1.1\msvc2010_opengl\lib\Qt5Ftpd.prl

                1. create file in directory
                  c:\Qt\5.1.1\5.1.1\msvc2010_opengl\include\QtNetwork
                  QFtp
                  and inside add
                  @#include "qftp.h"@

                2. copy from source two file
                  qftp.h and qurlinfo.h to includes\QtNetwork\

                3. in my project add
                  @LIBS += Qt5Ftp.lib@
                  and
                  @QT += ftp@

                and project finaly build and run:) jupiiii

                    Hello, I'm on Linux and I have the same problem. Compile the module as shared and static and in no way I can compile the examples. When you modified the .pro filedo not miss you put a -L parameter?

                      hi,
                      doesn't fit 100% to the theme, but I have tried it according to the instructions, but with the Creator.
                      The compilation works so far. However I have 3 problems:

                      cd qftp\ && C:\Qt\5.14.0\mingw73_32\bin\qmake.exe -o Makefile C:\Qt\qt-everywhere-src-5.14.0\qtbase\src\qtftp\examples\qftp\qftp.pro -spec win32-g++ "CONFIG+=qtquickcompiler"
                      Project ERROR: C:/Qt/qt-everywhere-src-5.14.0/qtbase/src/qtftp/examples/qftp/qftp.pro installs target to unexpected location.
                      mingw32-make[1]: *** [Makefile:43: sub-qftp-qmake_all] Error 3
                      mingw32-make[1]: Leaving directory 'C:/Qt/qt-everywhere-src-5.14.0/qtbase/src/build-qtftp-Desktop_Qt_5_14_0_MinGW_32_bit-Release/examples'

                      i simply removed module_qtftp_examples
                      I don't know if this is OK but now the compilation is running. And since they are only examples I think I should not have any problems.

                      Cannot read C:/../../tests/auto/other/headersclean/headersclean.pri: No such file or directory
                      

                      i have no solution for this, but i don't know if my mistakes result from this.

                      after compiling I only have the following files
                      libQt5Ftp.a
                      Qt5Ftp.dll
                      Qt5Ftp.dll.debug

                      but I still need
                      libQt5Ftpd.a
                      Qt5Ftpd.dll
                      but they're not made, so can anyone help me?

                        Hi
                        The names with d in the end - is normally the debug versions and
                        you are building in release mode so why you think you also need them ?
                        For debugging ?
                        Try build in debug mode and see.

                              Hi
                              Did you build both things in Debug then ?

                                I have compiled the QFtp once in release mode and once in debug mode.
                                I only got the files in each case:
                                libQt5Ftp.a
                                Qt5Ftp.dll

                                C:/Qt/Tools/mingw730_32/bin/../lib/gcc/i686-w64-mingw32/7.3.0/../../../../i686-w64-mingw32/bin/ld.exe: cannot find -lQt5Ftpd

                                the error i get now is from a project that was running with QFtp before. i have now installed the latest QT version and wanted to include QFTP there again so i can continue using the project.
                                I have tried to compile this project in debug modus

                                  I have compiled the QFtp once in release mode and once in debug mode.
                                  I only got the files in each case:
                                  libQt5Ftp.a
                                  Qt5Ftp.dll

                                  You get this error when you try to use the Qt5Ftp from your app right ?

                                    yes if i try to compile it.

                                    I have tried now to compile QFTP on a other system.
                                    There it works i get the 4 files.

                                    Now i have test to compile my project on this machine, i have the same error.

                                      ok but if you get the dlls then
                                      just make sure you use the right version
                                      for the app.
                                      Release DLL for Release App
                                      and Debug Dll ( d in name) for Debug App
                                      Dont mix it.

                                      Also make sure the path you add to your pro file matches where you put the dll.

                                        Have been trying to get QFtp to work myself for 2 days now, think I'll just go back to the stoneage for this one app and use a very old qt with FTP..

                                        Have been doing amazing things with Qt.. from 3D to automation control and sensing, but this one library will have me going nuts if I don't stop trying...

                                        Thumbs up to everyone being able to get a usable lib out of this :)
