Project error: unknown module QT: webkitwidgets

T4QT

Hi,
I found few posts about this problem and my problem is not related to compilation of webkit.
I have QT compiled with both Qtwebkit and Qtwebkitwidgets. Now I am trying to use them in my project file like
QT += webkit and QT += Qtwebkitwidgets.

But I am getting above error:

Now I changed the project file as follows:

Qt_MODULES += webkitwidgets
Qt_MODULES += webkit

Now this time it generated the Makefile but when I am trying to use #include <QtWebKitWidgets> and #include <QtWebKit> in my application it says No such file or directory.

Thanks

QT = core gui widgets webkit webkitwidgets

Do not put that "Qt" in front of "webkitwidgets".

No I am not using QtWebkitwidget or Qtwebkit.

QT = webkit webkitwidgets.

Project error: Unknown modules in QT: webkit webkitwidgets

Then I tried:
qmake -d

It gave me following:

DEBUG 1: qt_src/qtbase/mkspecs/features/qt_functions.prf:172 : calling built in error ("unknown module in QT: webkit webkitwidgets)

Project error: Unknown module in QT: webkit webkitwidgets

As I said, I have both compiled and their libraries were in their respective folders and not at qbase/lib folder.

Does this give some clue?

They should have been copied to qtbase. Maybe you should run make install?

hi thanks for your reply.

I moved my application folder within the qt_src folder and ran the similar command: qmake -o Makefile test.pro and it worked without any problem.
I am not getting this stringent behaviour?

Now fell into another issue: when I'm trying to deploy this test application, I copied my executable at the /bin directory and all the qt libraries at the /lib directory. I also put my plugins at /plugins/platform and fonts at /lib/fonts and now I am trying to run the application as below:

#~/bin/bash
export LD_LIBRARY_PATH=./lib
export QT_QPA_FONTDIR=./lib/fonts
export QT_QPA_PLATFORM_PLUGIN_PATH=/plugins/platforms

and running the application:

./qt_test -platform linuxfb -display fb:/dev/fb3

Now it says: This application failed to start because it could not find or load the Qt platform plugin "linuxfb".

I am wondering why it is giving this error, Unfortunate thing is I managed to run the application 2 days before and after doing some changes it is not running now.

Is this something related to how I created my makefile and generated the executable, because I am creating executable at one place and copying our to my target.

Thanks

Hi,

@export QT_QPA_PLATFORM_PLUGIN_PATH=/plugins/platforms@

I might be wrong but aren't your missing a . before /plugins ?

T4QT

no this is not an issue (it's typing error). Is my command:

./qt_test -platform linuxfb -display fb:/dev/fb3

correct?
