在utils.cpp中实现函数后追加对应的特化方式 template<typenameT>bool_tfunction(constT& args){// ...}templatebool_tfunction<A>(constA& args);templatebool_tfunction<B>(constB& args); 参考# c++ - undefined reference to template function - Stack Overflow
So for a template to work, the compiler intuitively needs two pieces of information: The template itself, and the type that should be substituted into it.When you declare the function template without defining it, you're only telling the compiler that such a template exists, but not what it...
You need to use theexportkeyword. However, I don't think G++ has proper support, so you need to include the template function's definition in the header so the translation unit can use it. This is because the<int>'version' of the template hasn't been created, only the<typename T>'ve...

in every translation unit that needs to use type_info even indirectly. For example when using a template function that is exported from a module the using ::type_info; must be in the consumer translation unit. For some reason it does not work in the template itself, e.g.: //Module.i...
