An idea?

Thank you.

I don't see this option  -prefix-install here http://qt-project.org/wiki/Building-Qt4-for-Blackberry 

I did not try x86 but was able to compile the latest code from this branch for arm yesterday.

I take my workds back! sorry, just got home and checked terminal window with Qt building process, I got exactly the same errors.

Looks like this commit broke the build

commit a37c2733b37857e1ca60d36653559c1528d72b64
Author: Bernd Weimer <bweimer@rim.com>

    Blackberry: implemented "orientation lock" widget attribute
    
    Qt::WA_LockPortraitOrientation and Qt::WA_LockLandscapeOrientation
    will be adhered to.
    
    This is not needed in Qt5, as those attributes have been removed from Qt5.

Thank you for the information.

I compiled by modifying the source code:
../TMP/qt/src/gui/kernel/ qwidget.cpp
-------------------------------------
...
        if (testAttribute(Qt::WA_AutoOrientation)) {
            navigator_rotation_lock(false);
        } // else {
            // navigator_set_orientation_mode((testAttribute(Qt::WA_LockPortraitOrientation) ?
                                            // NAVIGATOR_PORTRAIT : NAVIGATOR_LANDSCAPE), 0);
            // navigator_rotation_lock(true);
        // }
…
For my application under development is not serious I'll see later.

Due to the focus on BB10, Qt versions after 4.8.3 are no longer supported for the Blackberry Tablet OS.

Please use Qt 4.8.3, that should work fine.

Note that the change that was mentioned here was the only change that broke the build, but there are other changes which subtly break things at runtime, so don't try to get it to compile by commenting out stuff, there will be other problems. Use 4.8.3 instead.

Thank you for the info.
Necessary is to Qt4.8.4 Qt4.8.3.

I am confused, what's not supported on Blackberry Tablet OS and what shoud we use for Blackberry Tabled OS?

Is this http://qt-project.org/wiki/Building-Qt4-for-BlackBerry going to be updated?

Thanks.
