As Andreas pointed out and you've found out, the problem is mixing different Qt versions. Your headers are from Qt 5.5, as evidenced by the fact that the rvalue-ref QString::toLower() inline function was found (added in Qt 5.4, actually, in 19dd9a0ebd570ac134e115f2339912a1015ecde5), but the corresponding out-of-line implementation in toLower_helper() is missing during linking. This means your -lQt5Core found an older (< 5.4) version of QtCore. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/interest
