C++ Class Typedef Struct does not name a type

Question

I'm trying to make use of typedef structs inside of my C++ program. I started writing the following code until I received an error when trying to add a method to my class that returns a template typedef struct pointer. StructSource.h ``` template class StructSource { public: struct TestStruct{ T value; }; }; ``` User.h ``` #include "StructSource.h" class User { public: typedef StructSource::TestStruct IntStruct; IntStruct *getIntStruct(); }; ``` User.cpp ``` #include "User.h" IntStruct *User::getIntStruct() { return 0; } ``` This gives the following error when compiling with GCC. User.cpp:3:1: error: ‘IntStruct’ does not name a type I'm at a loss to explain why this is the case. What type information am I missing?

Accepted Answer

"User" is also a "namespace" (scope, actually, as most commenters point out - "namespace" was for a quick answer) here, so you have to use

```
User::IntStruct *User::getIntStruct() {
    return 0;
}
```
