QtWebKit and MinGW with QT 5.9

davidesalvetti

Hi all,

I found in this topic that it's possible to use QtWebKit with mingw(https://forum.qt.io/topic/83760/any-alternative-to-qtwebengine-for-mingw/11).

I have downloaded the folder from github but now I really don't know what to do with it to use QtWebKit in my project.

Can anyone give me any advice?

This is the link from where I downloaded the folder:
https://github.com/annulen/webkit/releases/download/qtwebkit-tp5/qtwebkit-tp5-qt58-mingw530-x86.zip

Thanks in advance.

@davidesalvetti You need to put the content of the archive into your Qt 5.8 installation: c:\Qt\5.8\mingw53_32

davidesalvetti

This means that it won't work for QT 5.9?

I put the content in c:\Qt\5.9.1\mingw53_32 and qt has found the

QT += webkitwidgets

now if I run my program it suddenly crash telling me "During startup program exited with code 0xc0000017" but only if I put this line in the code:

void MainWindow::on_actionOpen_Session_triggered()
{
    QWebView *view = new QWebView(this);
    view->load(QUrl("https://www.google.it/maps"));
    view->show();
}

I really don't understand why.

@davidesalvetti Well, it was built for 5.8, it is likely that you will have problems using it with 5.9.
Regarding the crash: is it crashing while starting or if you do something (calling on_actionOpen_Session_triggered())?

davidesalvetti

@jsulm Thank you for the answer.

It crashes while starting, it shows the mainwindow.ui and then it crashes. I don't call that action while starting my program so it never goes there. The strange thing is that when i comment

    QWebView *view = new QWebView(this);
    view->load(QUrl("https://www.google.it/maps"));
    view->show();

everything works well.

But at this point I don't know if this is just because I'm using QT 5.9 ...

jsulm

@davidesalvetti My guess is that your app is trying to load the QtWebkit DLL which is not compatible with your Qt version.

davidesalvetti

@jsulm Also mine. I will find another solution. Thank you for your time!

@davidesalvetti For Qt 5.9 you can use prebuilt binaries from https://github.com/annulen/webkit/releases/tag/qtwebkit-5.212.0-alpha2

davidesalvetti

@Konstantin-Tokarev I tried those binaries, but It gives me exactly the same problem.

Qt2019

@davidesalvetti
I have used ”qtwebkit-5.212.0_alpha2-qt59-mingw530-x86.zip“，it can compile OK，but it crashes when running the programe. my code is just a webview demo...

Konstantin Tokarev

@Qt2019 Does it crash when you load some site, or even with "about:blank"? If you are using debug build please try release.
