QT-Webkit 4.4.1 not detected by mythbrowser

[eric.bosch@…]

This may be a simple matter of configuration, but can somebody help out? I'm running on both a Gentoo 2008 and the latest Ubuntu distribution. Gentoo has QT4.4.1 and QT-Webkit 4.4.1 along with all other components of QT4.4.1 installed, rebuilt all of mythtv and mythbrowser. First of all, after I go into set up the mythbrowser and add a bookmark, the frontend locks up, and becomes unresponsive, however using no cpu. I have to kill mythfrontend to recover, but it does add the bookmark. If I try to open the bookmark, it tells me that QT Webkit > 4.4.0 is required, yet it is already installed. Any clues? Nothing shows in logs or console. Same issue on Ubuntu machine, but QT4.4.0 and QT-Webkit 4.4.0 are installed.

Broke by [18144].

One problem on Gentoo is configure is looking in the wrong place for the QtWebKit?/QWebView header.

Changing line 2678 in configure to

check_header qt4/QtWebKit/QWebView

allows configure to find the header but it still isn't being enabled for some reason.

Actually configure is still failing to find the header properly as these errors from config.err show:-

[Janne Grunau]

it's mainly gentoo's fault for installing Qt4 in a non-standard location.

It's not a problem for building mythtv since qmake spec file fortunenately has the proper include path.

I'll fix this.

[Janne Grunau]

as workaround adding --extra-cflags="-I/usr/include/qt4" should do

[Janne Grunau]

gentoo_qt4_include_path.diff should fix the issue on gentoo but will still break if qt4 headers are installed in a different non-standard include directory.

Still fails with your patch

check_header QtWebKit/QWebView -I/usr/include/qt4
check_cpp -I/usr/include/qt4
BEGIN /tmp/ffmpeg-conf-16721-21379-2844.cpp

This does work though

check_header QtWebKit/QWebView -I/usr/include/qt4 -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtWebKit

Janne's patch did work on my Gentoo box, but not on my Ubuntu. I'm rebuilding with the updated changes on Ubuntu now and will let you know if it works there. Is the non-standard location of the qt4 install due to coexistence of qt3/qt4 on the box? Seems if it's a non-standard location, there are two vendors with it at the same location.

[eric.bosch@…]

After two builds and one typo, this does work on Ubuntu.

[Janne Grunau]

(In [18165]) Fixes #5624, Adds Gentoo's and Ubuntu's non standard Qt4 include path to the QtWebKit? header check

[Alan Calvert <cal@…>]

On my systems qt4 is installed at /usr/local/qt4, which seems pretty reasonable. Would it be a "very bad thing" to add -I$QTDIR/include to the search path?. Fixes it for me.
