Hi there.
I intend to simulate a target cache memory design, involving some modifications to the ruby cache memory, coherency protocol, and so on.
It's necessary for me to add a global component to the CMP system, so I choose to implement it in Abstractchip.h, which contains the base class needed by the generated Chip.h, after new member  functions are added, I tried to make ruby but error emerges.

===========================
make log:
slicc_interface/AbstractChip.

h: In member function `void AbstractChip::BankRemap()':
slicc_interface/AbstractChip.h:175: error: invalid use of undefined type `struct CacheMemory<L1Cache_Entry>'
slicc_interface/AbstractChip.h:84: error: declaration of `struct CacheMemory<L1Cache_Entry>'
slicc_interface/AbstractChip.h:178: error: invalid use of undefined type `struct CacheMemory<L1Cache_Entry>'
slicc_interface/AbstractChip.h:84: error: declaration of `struct CacheMemory<L1Cache_Entry>'

=================================================
the error code:
template<class ENTRY> class CacheMemory;                           :84
                 .....
Vector < CacheMemory<L1Cache_Entry>* > m_L2Cache_L2cacheMemory_vec;
                 .....
m_L2Cache_L2cacheMemory_vec.ref(i)->VictimReg.lookup(i).m_LastRef.   :175
============================

It seems the error occurs because I direct refer the member function of  "m_L2Cache_L2cacheMemory_vec.ref(i)", which is an instantiation of Cachememory object, but I see nothing illegal here since class L1Cache_Entry will be generated and Cachememory is well defined in Cachememory.h, 
what's wrong with it? or do I have to modify the generted Chip.h rather than abstractchip.h? I'm so dumb!
Thanks for your advice and help!
