Problems with template instantiation in C++
I use the the g++ 4.3.2 compiler on my linux machine. If I compile the following piece of code I get a bunch of compiler time error. In my opinion the compiler
have all information to process the code properly. I can't imagine, what's
going wrong?
Sorry for the long code portion, but I have reduced the code as much as possible! You can view the source code and additionally the compiler error message!
