Using boost memory pool in class

Question

I tried to declare a memory pool in my class.

But the compiler shows some basic error like missing ')' before ';'

or syntax error : 'sizeof'

It works well if I used the pool as local variable but I really want to make it live with the class.

What's wrong about my usage?

Here is the class, the MAX_OBJ is a const

class CData
{
public:
 CData(void);
 ~CData(void);
private:
 boost::pool m_Pool(sizeof(DWORD) * MAX_OBJ);
};

Answer 1

I don't think it as anything to do with boost::pool.

But this line:

boost::pool m_Pool(sizeof(DWORD) * MAX_OBJ);

Should probably be:

boost::pool m_Pool;

And your constructor should then be:

CData::CData() :
  m_Pool(sizeof(DWORD) * MAX_OBJ)
{
}

You cannot construct members in the class declaration. You can just say: "My class has a member named m_Pool whose type is boost::pool."

You then specify in one or several constructor(s), how this member is initialized.
