undefined reference to `template_function<type>(parameters)' 其中template_function是模板函数的名称,type是模板参数的具体类型,parameters是函数的参数。 2. 检查模板定义和实现是否正确 确保你的模板定义和实现没有语法错误。模板的定义通常放在头文件中,而实现可以选择放在头文件中或单独的源文件中。但需要...
It's a template for creating functions as needed.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 ...
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

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...

So in every function there should be no '__declspec' command because the define is empty. This leads to the desricbed error. After your hints I tested it with deleting also the dllimport in the second branch (althrough not used at all). Now it works. Strange behaviour....
