I was having issues debugging an import problem for a custom
QDeclarativeExtensionPlugin.
The ultimate problem was that I forgot to install a required shared library
used by my plugin. However, qmlviewer reported the problem as follows:
# QML_IMPORT_TRACE=1 qmlviewer gesture.qml
QDeclarativeImportDatabase::addImportPath "/usr/lib/qt4/imports"
QDeclarativeImportDatabase::addImportPath "/usr/bin"
QDeclarativeImportDatabase::addToImport 0x24d37c "." -1.-1 File as ""
QDeclarativeImportDatabase::add: loaded "/home/user/gestureEngineTest/qmldir"
QDeclarativeImportDatabase::importPlugin ".home.user.gestureEngineTest" from
"/home/user/gestureEngineTest/lib/libgestureengine.so"
QDeclarativeImportDatabase::addToImport 0x24d37c "Qt" 4.7 Library as ""
file:///home/user/gestureEngineTest/gesture.qml:3:1: GestureEngine is not a
type
GestureEngine {
where GestureEngine is defined in libgestureengine.so, but it doesn't convey
that the plugin import failed. In fact, the trace leads you believe the plugin
was successfully loaded.
It would be nice if qmlviewer displayed an error like the following:
error while loading shared libraries: libqt_gesture_lib.so.1: cannot open
shared object file: No such file or directory
