这是我的dialog程序 QDialog.rar (8 K) 下载次数:2 我照书上写了一个非常简单的程序，结果却报了如下错误，我实在不知道怎么做，请各位帮忙！谢谢！E:\QtIDEinstallation\MinGW\include\c++\3.4.5/bits/cpp_type_traits.h:334: error: expected identifier before '__is_pod'E:\QtIDEinstallation\MinGW\include\c++\3.4.5/bits/stl_tree.h:334: error: declaration of 'typedef struct std::_Rb_tree_node<_Val> std::_Rb_tree<_Key, _Val, _KeyOfValue, _Compare, _Alloc>::_Rb_tree_node'E:\QtIDEinstallation\MinGW\include\c++\3.4.5/bits/stl_tree.h:395: error: expected unqualified-id before '__is_pod'E:\QtIDEinstallation\MinGW\include\c++\3.4.5/bits/stl_tree.h:575: error: request for member '_M_key_compare' in '((const std::_Rb_tree<_Key, _Val, _KeyOfValue, _Compare, _Alloc>*)this)->std::_Rb_tree<_Key, _Val, _KeyOfValue, _Compare, _Alloc>::_M_impl', which is of non-class type 'const int'……………几十条关于stl_tree.h的错；还有我的tools-->options-->Qt4-->Qt versions的auto-detected的debugging helper是个“X”。我不知道怎么改？请赐教！
