Configure script is errorless ... but i get bad compilations errors, and i cannot found a workable solution ...

Here are the last lines on compile :

/home/goth/showeq/src/gdbmconv.cpp:310: undefined reference to `QString::QString(QString const&)'
gdbmconv.o: In function `GDBMIterator::GetFirstKey(QString, Datum&)':
