Windows下源码编译Qt-Android

参考文章：Building qt-android on windows

set ANDROID_API_VERSION=android-19
set ANDROID_SDK_ROOT=D:\android\sdk

mingw32-make.exe -j2

编译报错：

  409: template <typename T>
  410: Q_INLINE_TEMPLATE void QList<T>::node_destruct(Node *from, Node *to)
  411: {
  412:    if (QTypeInfo<T>::isLarge || QTypeInfo<T>::isStatic)
  413:        while(from != to) --to, delete reinterpret_cast<T*>(to->v);
  414:    else if (QTypeInfo<T>::isComplex)
  415:        while (from != to) --to, reinterpret_cast<T*>(to)->~T();
  416: }

...when compiled for ARM, causes this warning (or error with -Werror):

  src/corelib/tools/qlist.h: In member function ‘void QList<T>::node_destruct(QList<T>::Node*, QList<T>::Node*) [with T = QVariant]’:
  src/corelib/tools/qlist.h:738:5:   instantiated from ‘void QList<T>::dealloc(QListData::Data*) [with T = QVariant]’
  src/corelib/tools/qlist.h:714:9:   instantiated from ‘QList<T>::~QList() [with T = QVariant]’
  src/corelib/statemachine/qstatemachine.h:81:59:   instantiated from here
  src/corelib/tools/qlist.h:415:28: error: cast from ‘QList<QVariant>::Node*’ to ‘QVariant*’ increases required alignment of target type [-Werror=cast-align]

解决方法：
因为在编译QTDIR\qtscript时报错，所以将文件夹下Miakefile里的-Wcast-align去掉，再编译就可以了。
