Unknown module(s) in QT: openssl-linked

[TheFlyingMooseMan]

First line in my .pro file:

QT       += core gui widgets sql xml network webenginewidgets multimedia httpserver openssl-linked

Qt Creator: 12.0.1
Qt: 6.6.0
OS: macos sonoma 14.0

I figured out that SSL may be an issue when my http://... network request came through, but my https://... requests did not.

Anything I should look at, compile, change...?
Feedback is much appreciated!

openssl-linked

This is not a Qt module so qmake is right in rejecting it.

I think on macOS Qt uses Apple's secure libraries by default so it should "just work". If you want to force using OpenSSL, you need to download / compile OpenSSL and link it to your project (either at runtime using LD_LIBRARY_PATH or by rpath).

@sierdzio How do I make sure that this is working?

I have the following code to send the network request:

		QNetworkAccessManager* n=new QNetworkAccessManager(this);
		connect(n, SIGNAL(finished(QNetworkReply *)),
				this, SLOT(handleImageDataNetwork(QNetworkReply*)));

		n->get(QNetworkRequest(QUrl(urlString)));
		return;

And the following code to process the network reply:

    if(r->error()==QNetworkReply::NoError)
    {
        if(r->open(QIODeviceBase::ReadOnly))
        {
            qDebug() << SB_DEBUG_INFO << r->bytesAvailable();
            QByteArray a=r->readAll();
            qDebug() << SB_DEBUG_INFO << a.length();
            if(a.length()>0)
            {
                qDebug() << SB_DEBUG_INFO;
                QPixmap image;

                //	Store in cache
                image.loadFromData(a);
                _storeInCache(&a);
                emit imageDataReady(image);
            }
        }
    }

Running will yield the following output:

0x1e19bd300 "08:45:53" ../app/ExternalData.cpp handleImageDataNetwork 367 bytesAvailable: 0
0x1e19bd300 "08:45:53" ../app/ExternalData.cpp handleImageDataNetwork 369 length: 0

Anything I missed?

Hi,

Are you in control of the server ?
You can also use Wireshark to analyze the traffic you have.

@SGaist Not in control of the server, but I was able to confirm that data was sent back from the server using Wireshark (thanks for the suggestion).

Oh well. I am calling wget to get things accomplished. Nice work around that also takes care of redirects and all that.
