Simple boost smart pointer syntax issue

Question

When using either boost::scoped_ptr or boost::shared_ptr I get the error

1>*\algomanager.cpp(28) : error C2064: term does not evaluate to a function taking 1 arguments

I have code like this . . .

class X{
  boost::shared_ptr<cPreFilterProcess> preProcess;
public:
  X(){
    preProcess(new cPreFilterProcess(pars));
  }
};

What am I missing? Thanks.

My mythical glass orb of magic debugging tells me you're doing something like this:

class X{
  boost::shared_ptr<cPreFilterProcess> preProcess;
public:
  X(){
    preProcess(new cPreFilterProcess(pars));
  }
};

You need to use either the member initializer like:

X() : preProcess(...){}

Or use .reset since your can't just assign a pointer like that:

X() { preProcess.reset(...); }

I would strongly recommend the first option though.
