IDCS5 Win K2Vector IPMFont::FontProtection question

Question

I have this code several places in my project:
        K2Vector<IPMFont::FontProtection>* ProtectionList = Font -> GetProtection();
        K2Vector<IPMFont::FontProtection>::iterator iter;
        for(iter = ProtectionList -> begin(); iter != ProtectionList -> end(); ++iter)
//         do some stuff...
       delete ProtectionList;
This code is modeled after the sample code found in the SnpInspectFontMgr.cpp sample snippet:
                K2Vector<IPMFont::FontProtection> *fontProtection = font->GetProtection();
                K2Vector<IPMFont::FontProtection>::iterator iter;
                bool16 dumpInfo = !(fontProtection->size() == 1 && fontProtection->front() ==IPMFont::kNormal) ;
                for (iter = fontProtection->begin(); iter != fontProtection->end(); ++iter)
//                  do some stuff...
                delete fontProtection;
The problem is that when I include the "delete ProtectionList" line of code I get a linker error, to wit:
error LNK2019: unresolved external symbol "public: void __thiscall K2Internals::K2VectorBase<enum IPMFont::FontProtection,class K2Allocator<enum IPMFont::FontProtection> >::DoCleanup(void)"
If I leave out the "delete FontProtection" line of code the plugin compiles and links without errors, but I get a large number of leaks when I run it, and after several hours of careful, step-by-step, line-by-line debugging, I have definitely isolated the leaks to the missing delete call.
Does anyone know what I am doing wrong here?
TIA!

Answer 1

I found the problem.
For those of you who are required to use K2Vector, please be advised that there is a K2Vector.tpp file that you probably should include in your code.  It has a handful of additional member functions that K2Vector may call.  I suspect that when ProtectionList calls its destructor, there is a call to one of those functions.
I added this line to my code:
#include              "K2Vector.tpp"
and the linker error disappeared.
For the record, a quick search of the SDK documentation and the K2Vector.h header makes no mention of this additional file.  I discovered that I needed it when I made a close inspection of the snippet and discovered its inclusion at that time.
