Building Qt creator with private headers

[diocletian74]

I have built a qt4.8 for the Freescale i.mx6 ART board and I have successfully integrated the qt4.8 qmake into qtcreator. However, when I try to view my qml scripts with the designer tab in qtcreator, the designer tab is always grayed out. I learned that the problem is the qmldesigner plugin did not build because the qmldesigner plugin requires private headers. I built qt with the configuration option -developer-build, and built the qtcreator. Also when I built qtcreator according to the instructions in the qtcreator readme file and told the qmake where to find the private headers in the qt-source build tree.

Both times I built qt-creator I get this error

/usr/bin/ld: skipping incompatible /usr/local/Trolltech/Qt-4.8.4/lib/libQtDeclarative.so when searching for -lQtDeclarative

Any advice will be helpful
