Error running Snowshoe - "undefined symbol: _ZNK13QQuickWebView10metaObjectEv"

[Prabindh Sundareson]

When using Qt5.0.0, and the latest snowshoe from gitorious, I am facing an issue of not being able to run with "./snowshoe --mobile". I am using eglfs platform.  Is there a specific build option for Qt5 webkit that I need to enable to resolve the below issue ? It appears to be a moc issue, but I cannot find which library needs to be linked to fix this.

loaded library "<>/qml/QtWebKit/libqmlwebkitplugin.so"
QLibraryPrivate::loadPlugin failed on "<>/qml/QtWebKit/libqmlwebkitplugin.so" :
"Cannot load library <>/qml/QtWebKit/libqmlwebkitplugin.so: (<>/qml/QtWebKit/libqmlwebkitplugin.so: undefined symbol: _ZNK13QQuickWebView10metaObjectEv"

Dear Prabindh

It works fine with Qt 5.0.1 as also with WebKit from trunk. I would start by updating you Qt version, you can check at: http://qt-project.org/downloads

Hello Adenilson,

Thanks for the response. Has this been tested on an ARMv7 - Linux build ?

That problem that you're seeing is architecture independent and most likely
due to an incorrect library search path (maybe LD_LIBRARY_PATH?). Try
strace'ing the startup to see which libraries it is linking against and you
should see that it tries to load from the wrong path (maybe a Qt4
libQtWebKit?)

I would also test for the system variable QML_IMPORT_PATH, since it seems to be failing to import webkit's qml plugin.

The problem with QML_IMPORT_PATH can be fixed with https://gist.github.com/rafaelbrandao/4709929

If you guys believe this is the right fix, feel free to land it.

Hello Rafael, I dont think it has to do with QML IMPORT PATH, as it would not have loaded the .so in the first place.

To close this issue - I tried with Qt5.0.1, and it builds and works fine, on my ARMv7 platform. To put this in context - I am trying to close out on this bug - https://bugreports.qt-project.org/browse/QTBUG-29729

By the way - Closing the last tab of the browser (in desktop mode), causes a segfault in libQt5WebKit.so.5. Is this a known bug and tracked somewhere ?

Also - where can I get to know redistribution rights associated with Snowshoe browser ?

I'm happy that Qt 5.0.1 did the trick.

I tested snowshow in Desktop using WebKit from trunk and also Qt 5.0.1, it will not crash while closing the last tab. Maybe is it an ARM issue? Are you able to collect a core file and provide the backtrace using gdb?

Concerning snowshoe licencing, check the file "LICENSE" in repository (it is LGPL license).

Just for information - posting my blog post on usage of snowshoe for experimentation with HTML5, please find below:
