Several things about this post make me think you're asking something wrong:

  • Your "C" code includes a template. That's not C. Are you using some extension or something?
  • Your "C++" code includes "public class ..." - the public keyword is misplaced there, and should generate its own warning before the one you point out.
  • Your C++ code includes a List, not a list.


Is this really C and C++ code, respectively? Also, is the error you show the very first error the compiler generates?

You should be able to declare what you did. For example, this:

Code:
#include <list>

class Thing {
    std::list<Thing> stuff;
};

Compiles just fine for me, even with the -Wall, -Wextra and -pedantic flags.

Could you give a short (but full and compilable) example that demonstrates your problem?

An indirect_array is a reference to the actual elements of an array specified by an ordered array of indices. The way to get an indirect_array is to call operator[](valarray<size_t>) on a valarray. The returned indirect_array then permits carrying operations out on the referenced subset of elements in the original valarray. For example, if an indirect_array is obtained using the array (4,2,0) as an argument, and then assigned to an array containing (1,2,3), then the underlying array will have array[0]==3, array[2]==2, and array[4]==1. Parameters: Tp Element type. Definition at line 84 of file valarray.
