c++ - msys2 静态 QT undefined reference 问题

Question

最近重温了一些QT代码，然后写了一些简单的东西。适用于动态 QT，但是当使用 qt5-static 中的 qt make 时，我得到

debug/editor.o: In function qMain(int, char**)': C:\msys64\home\tim\Projects\editor/editor.cpp:6: undefined reference to__imp__ZN12QApplicationC1ERiPPci' C:\msys64\home\tim\Projects\editor/editor.cpp:7: undefined reference to __imp__ZN9QTextEditC1EP7QWidget' C:\msys64\home\tim\Projects\editor/editor.cpp:8: undefined reference to__imp__ZN7QWidget4showEv' C:\msys64\home\tim\Projects\editor/editor.cpp:9: undefined reference to __imp__ZN12QApplication4execEv' C:\msys64\home\tim\Projects\editor/editor.cpp:7: undefined reference to__imp__ZN9QTextEditD1Ev' C:\msys64\home\tim\Projects\editor/editor.cpp:6: undefined reference to __imp__ZN12QApplicationD1Ev' C:\msys64\home\tim\Projects\editor/editor.cpp:7: undefined reference to__imp__ZN9QTextEditD1Ev' C:\msys64\home\tim\Projects\editor/editor.cpp:6: undefined reference to `__imp__ZN12QApplicationD1Ev'

对于

#include <QApplication>
#include <QTextEdit>

int main(int argv, char **args)
{
        QApplication app(argv, args);
        QTextEdit textEdit;
        textEdit.show();
        return app.exec();
}

链接器似乎在引入所有正确的东西

一切都应该安装

$ pacman -Ss qt5-static mingw32/mingw-w64-i686-qt5-static 5.10.0-2 (mingw-w64-i686-qt mingw-w64-i686-qt5) [installed] A cross-platform application and UI framework (mingw-w64-static) mingw64/mingw-w64-x86_64-qt5-static 5.10.0-2 (mingw-w64-x86_64-qt mingw-w64-x86_64-qt5) [installed] A cross-platform application and UI framework (mingw-w64-static)

我用 qmake -project 制作了 pro 并添加了 QT += widgets。 'qmake'(动态)有效，但 '\mingw64\qt5-static\bin\qmake' 导致 undefined reference 。非常感谢任何提示。

我不得不重新安装 mingw64/mingw-w64-x86_64-qt5-static 然后它工作了。
