Hello, I am having a problem with a template class I created. The problem I am having concerns how to use it. here is how I have my files set up... --------------- chash.h I define the template class here... --------------- chash.cpp The implementation of the template class is here... --------------- now I want to use this class elsewhere in other files, this is where I am having problems. I have a manager type class that contains an instance of the template hash class, like this --------------- manager.h #include "chash.h" chash *framehash; --------------- manager.cpp //in the constructor framehash = new chash; --------------- Now here comes the problem, everything compiles ok but I get linker errors saying basically that manager.obj cant find the chash functions to link to. I can solve this by explicitly instantiating a chash inside chash.cpp... which becomes --------------- chash.cpp template class chash; //the rest.. --------------- I cant put the explicit instantiation anywhere else or I get compile errors. This just does not seem right to me. chash.cpp should not be ''aware'' of all the classes that will use it - that seems to defeat the purpose. All the examples of using template classes in every book I have put all the code into one file. I am just unsure how to do it and span it to many files. Hope you can understand my problem, Maybe if anyone has any example of using a template class in a practical - multifile - project. thanks, BrianH
