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

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
