Can't find webkitwidgets

Phamy1289

I've installed Qt 5.11.3 and QtCreator 4.4.1 on Centos 8. When I tried to run my project, I get an error stating:

"Project MESSAGE: Normal Build
Project ERROR: Unknown module(s) in QT: webkitwidgets
12:47:30: The process "/home/hpham/DevEnv/Qt5.11/5.11.3/gcc_64/bin/qmake" exited with code 3.
Error while building/deploying project SPIT_MP (kit: Desktop)
When executing step 'qmake'"

I installed the qt5-webkit-devel, but it didn't fix the issue. Am I missing anything?

QtWebKit was removed with Qt 5.6. You can either add it yourself from the repos.
Or better, port your project to QtWebEngine

Oh, I see. Is the same true for QWebView?

when you talk about the widget used to display QtWebKit then yes of course.
If you talk about the QtWebView module, then no. this is uses QtWebEngine

Ok, I got it thanks. I will try to add it myself from the repos before I port my project. Thank you

I tried porting the project to QtWebEngine and now I'm getting linker errors stating that QtCore and stdc++ are incompatible with Qt5.11.3. What versions of the two would be compatible with Qt5.11.3?

QtCore and stdc++ are incompatible with Qt5.11.3

Looks like you're mixing two different Qt versions.
Please show the whole error.

The following is what is displayed when I try to build my project:

I'm using QtCreator 4.4.1 and Qt Library 5.11.3

I just found out what I was doing wrong. I had set the wrong bit for the compiler. It was set to 32bit instead of 64bit. Thanks for the help, especially the news about QWebKit being depricated. I'll mark it as solved.
