qscintilla2：架構x86_64的未定義符號

Question

我有一個靜態Qt並在macOS 10.12.4上重新編譯qscintilla2_qt5.a（2.10）。當我編譯我的項目，它打印此錯誤：

Undefined symbols for architecture x86_64: 
    "qRegisterDraggedTypes(QStringList const&)", referenced from: 
     initialiseRectangularPasteboardMime() in libqscintilla2_qt5.a(MacPasteboardMime.o) 
    "QMacPasteboardMime::count(QMimeData*)", referenced from: 
     vtable for RectangularPasteboardMime in libqscintilla2_qt5.a(MacPasteboardMime.o)

這是需要添加QT + = macextras在* .pro文件，當Qt的staticaly建。我不知道爲什麼，但是當程序建立在共享的Qt中時，它沒有這個工作，但是這個工作沒有這個macextras。
