【求助】求教一个opie移植到arm的问题

:confused: 交叉编译opie时提示其中的freetype目录中的文件出错：
freetypefactoryimpl.o freetypefactoryimpl.cpp
freetypefactoryimpl.cpp: In destructor `virtual FreeTypeFactoryImpl::~FreeTypeFactoryImpl()':
freetypefactoryimpl.cpp:31: warning: possible problem detected in invocation of delete operator:
freetypefactoryimpl.cpp:31: warning: invalid use of undefined type `struct QFontFactoryFT'
freetypefactoryimpl.h:24: warning: forward declaration of `struct QFontFactoryFT'
freetypefactoryimpl.cpp:31: note: neither the destructor nor the class-specific operator delete will be called, even if they are declared when the class is defined.
freetypefactoryimpl.cpp: In member function `virtual QFontFactory* FreeTypeFactoryImpl::fontFactory()':

不知道是怎么回事涅，freetype之前已经交叉编译成功了，大虾们帮帮忙，谢谢哈
