The first two fatal compilation errors I get are:
qtdensity.cpp:37:31: error: allocation of incomplete type 'QLineEdit'
QLineEdit *cmdEntry = new QLineEdit(m_cmd);

qtdensity.cpp:38:14: error: no matching member function for call to 'connect'
QObject::connect(cmdEntry, SIGNAL(textEdited(QString)), this,...
/usr/local/Qt-5.0.2/include/QtCore/qobject.h:199:36: note: candidate function
not viable: cannot convert argument of incomplete type 'QLineEdit *' to
'const QObject *'
static QMetaObject::Connection connect(const QObject *sender, const...
The fatal errors occur when processing Qt header files, so perhaps I
have a problem with my Qt installation.
