Re: [Boost-users] Cyclic includes when using smart pointers.

Oh ok, now I feel dumb. :( I thought that because it was a template, I couldn't forward declare it because the template would need information about the class. I might still have some issues when I start inlining, but I should be able to work around them. Jared On Tue, Mar 31, 2009 at 9:12 AM, Peter Dimov wrote:

I have the following situation, simplified down.

Header file 1:

class Test1 { vector<Test2Ptr> mTest2Objects; };

typedef boost::shared_ptr<Test1> Test1Ptr;

Header file 2:

class Test2 { vector<Test1Ptr> mTest1Objects; };

typedef boost::shared_ptr<Test2> Test2Ptr;

Now normally I'd get around this easily by doing a forward declaration, but I can't do that with a smart pointer definition.

Why not? With raw pointers you'd do:

class Test2;

class Test1 {   vector mTest2Objects; };

With shared_ptr you do

class Test2;

class Test1 {   vector< shared_ptr<Test2> > mTest2Objects; };
