[Solved] QFtp and qt5 linking problem

[grastvei]

They have removed QFtp from qt5 and I've to download it and compile it myself.
The project files for qftp:

@TEMPLATE = subdirs

module_qtftp_src.subdir = src
module_qtftp_src.target = sub-src

module_qtftp_examples.subdir = examples
module_qtftp_examples.target = sub-examples
module_qtftp_examples.depends = module_qtftp_src
!contains(QT_BUILD_PARTS,examples) {
module_qtftp_examples.CONFIG += no_default_install no_default_target
}

module_qtftp_tests.subdir = tests
module_qtftp_tests.target = sub-tests
module_qtftp_tests.depends = module_qtftp_src
module_qtftp_tests.CONFIG = no_default_install
!contains(QT_BUILD_PARTS,tests):module_qtftp_tests.CONFIG += no_default_target

SUBDIRS += module_qtftp_src
module_qtftp_examples
# module_qtftp_tests \

@

project file in src:
@
TEMPLATE = subdirs

SUBDIRS += qftp

@

and the qftp pro file:
@
load(qt_build_config)
Template = lib
TARGET = QtFtp
CONFIG += static shared
#CONFIG -= shared
QT = core network

MODULE_PRI = ../../modules/qt_ftp.pri
MODULE = ftp

load(qt_module)

Input

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

This compiles and give me the dll I need. But the problem is when I want to use it in a project.

I've got this in my project file:
@
#-------------------qtftp--------------------------
QTFTP_PATH = ../3rdparty/qt5/qtftp
CONFIG(debug, debug|release):QTFTPLIB = Qt5Ftpd
CONFIG(release, debug|release):QTFTPLIB = Qt5Ftp
INCLUDEPATH += $$QTFTP_PATH/src/qftp
LIBS += -L$$QTFTP_PATH/lib
-l$$QTFTPLIB

#--------------------------------------------------
@

But after i run qmake it ads "500" to the lib and it gives me the following error

c:/qt/qt5.1.1/tools/mingw48_32/bin/../lib/gcc/i686-w64-mingw32/4.8.0/../../../../i686-w64-mingw32/bin/ld.exe: cannot find -lQt5Ftpd500

if i open the make.debug I can se that qmake rename the qt5ftp lib to qt5ftp500.

Is there a configuration that tells qt to append the version number? It explains the numbers but not how they got there.

Hi,

What do you wish to do with QFtp? QNetworkAccessManager has taken over some of QFtp's functionality: http://qt-project.org/forums/viewthread/27981 Would that suit your needs?

[grastvei]

I'm porting a program from qt 4.8 to qt 5.1 and it uses QFtp.

[JKSH]

I see.

Try subscribing to the "Interest mailing list":http://lists.qt-project.org/mailman/listinfo/interest and asking your question there -- Qt's engineers are active on that list and they'll have better inside knowledge about these compatibility modules.

[grastvei]

the shared library QtFtp created a prl file. I added this file:
@CONFIG -= create_prl@
And now it works as expected.

Hello
In my case i not seeing

#include <QtFtp> or <QFtp>

but only

#include <QtFtp/QtFtpDepends>

[grastvei]

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
@

[darbor]

I have install QT 5.1.1
download from git https://qt.gitorious.org/qt/qtftp

extract to:
C:\Qt\5.1.1\5.1.1\Src\qt-qtftp

edit qftp.pro
@
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"@

go to VC console.

cd c:\Qt\5.1.1\5.1.1\Src\qt-qtftp\src\qftp
qmake qftp.pro
nmake
nmake install

after when I run examples from git qtftp i have this error

C:\Qt\5.1.1\5.1.1\msvc2010_opengl\examples\network\qftp\ftpwindow.cpp:43: błąd:C1083: Cannot open include file: 'QtFtp': No such file or directory

[grastvei]

I included qftp.h from library I build.

[darbor]

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;

[grastvei]

I can write more details about how to do this after work.

[darbor]

Hello
It's work

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

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

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

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

and project finaly build and run:) jupiiii

Thank you for sharing your solution!

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?
