Thanks in advance!

nmake install in the build folder if you are using Visual Studio and mingw32-make install if you are using MinGW

@SGaist After made make install I got the following:

As the error suggests: you are missing Perl. Install it.

It’s normal noting changed, the module wasn’t even built.

@SGaist During installation process of QT this problem occurred:

So I clicked 'Ignore'.
Then I tried to install "C:\Qt\Qt5.10.0\Tools\Perl52213_32\strawberry-perl-5.22.1.3-32bit.msi
but nothing changed.
I tried to reinstall it and disabled Antivirus and the same error appeared.
Is there anyway to overcome this problem?

SGaist · 2 Jan 2018, 09:53

Did it install successfully ?
If so did you try to call perl from a new command prompt ?

Ashi · 2 Jan 2018, 12:58

@SGaist I restarted the Qt command line and the error that related to Perl disappeared and I got the following:

Thanks for your response!

jsulm · A Ashi 2 Jan 2018, 09:53

@Ashi Shouldn't you "nmake install" what you cloned from the repository before?

git clone git://code.qt.io/qt/qtconnectivity.git
cd qtconnectivity
git checkout wip/win
...
nmake
nmake install

You should also use the correct command line prompt for building especially if you start with the one provided by Visual Studio.

Abdurahman_Gulamkadirov · A Ashi 27 Dec 2017, 04:24

@Ashi Sorry, I'm too late to answer this post. I think you should try with msvc compiler, not mingw
