Hi,

The old QFtp module might make your life easier.

[walter-j]

But Qt Creator does not recognize it. what can i do please?

[SGaist]

Clone it and build it.

[walter-j]

those links gave me a 404 error. sorry

[SGaist]

What links ?

[walter-j]

git://code.qt.io/qt/qtftp.git
http://code.qt.io/qt/qtftp.git
https://code.qt.io/qt/qtftp.git

[SGaist]

Those are links to use with the git clone command.

[walter-j]

please be patient with me im new in Qt. i have typed git clone git://code.qt.io/qt/qtftp.git. i have this message checking connectivity....done. what can i do else?

[SGaist]

This has nothing to do with Qt.

Didn't you get a new folder named qtftp ?

[walter-j]

yes . will i build it in Qt?

[SGaist]

Open the project .pro file with Qt Creator and build it.

By the way, what OS are you on ?

[walter-j]

linux mint 18 sarah

[walter-j]

i got this message : cannot create a directory / mkspecs/modules-inst when im building it

[SGaist]

Which version of Qt are you using to build that module ?

[walter-j]

Qt 5.7.1 . now i can build . what can i do else?

[walter-j]

my programm does not recognize QFtp but i have already built it

[SGaist]

Did you install the module ?
