标题[问题] 莫名的undeclare scope
时间Wed Dec 2 22:33:58 2009
以下是我程式片段的bug：
../../include/dlist.h: In constructor 'DList<T>::DList()':
../../include/dlist.h:41: error: '_head' was not declared in this scope
../../include/dlist.h:41: error: '_tail' was not declared in this scope
../../include/dlist.h: In destructor 'DList<T>::~DList()':
../../include/dlist.h:44: error: there are no arguments to 'clear' that
depend on a template parameter, so a declaration of 'clear' must be available
../../include/dlist.h:44: error: (if you use '-fpermissive', G++ will accept
your code, but allowing the use of an undeclared name is deprecated)
.......
我之前有类似的情况是在static funx未在.cpp档，instatiate的时候.....
但这次我真的搞不清楚了@@"
_head、_tail明明是Dlist class的private data member，为什麽它会看不到？同时，
adtTest.h也有出现以下complain：
adtTest.cpp:49: error: cannot define member function
'DList<T>::AdtResetCmd::exec' within 'DList<T>'
adtTest.cpp:63: error: cannot define member function
'DList<T>::AdtResetCmd::usage' within 'DList<T>'
......
(adtTest.cpp我都没碰啊~~~)
我已经确定应该没少{} (少了，它应该会红红的).....
请问像这样的情形可能有的其他原因是什麽？ (要我砍掉重练？？!)
谢谢大家的回答~

我即使想凭着"浩然正气"写程式也不能....因为.....
我只有"一股傻气".......囧
