从模板化 function 调用非模板化 function

Question

Hy. My question is that, I have a templated function in ah file and inside i want to call a function which was not implemented any templates, it's just a basic "declaration and definiton" func. It's possible to call a non-templated function from a templated one?

.h file

template <typename T>
void func(T &param){

   //do something...

   int p=func2(some param);
}

.cpp file

int func2(some param){
   int a;

   //do something..

   return a;
}

I got an error code: there are no arguments to 'func2' that depend on a template parameter, so a declaration of 'func2' must be available

Answer 1

After hours of googling i found the answer: In my.h file the

int func2(some param)

was declared after than the templated funcion. So the compiler did not see it. So correctly it looks like this:

int func2(some param);


template <typename T>
 void func(T &param){

   //do something...

   int p=func2(some param);
}
