$ whatis bc bc (1) - An arbitrary precision calculator language bc (1posix) - arbitrary-precision arithmetic language Install bc and it will work. It is used to get the Qt version in hex format from the x.y.z decimal format and pass it to the moc compiler. Without bc you should see moc invoked like this: moc-qt4 -DQT_VERSION=0x0 -o moc_FancyLineEdit.cpp ... Notice the -DQT_VERSION=0x0 flag, which should instead be something like -DQT_VERSION=0x040704. So, moc would be instructed that you have Qt version 0.0.0 and thus some part of the sources are omitted from compilation. Remember to remove the old moc_FancyLineEdit.cpp or to touch src/frontends/qt4/FancyLineEdit.h before launching make. -- Enrico
