Subject: [Boost-users] [Move] unique_ptr with boost vector container (C++98)
From: Gene Kang (gene.kang_at_[hidden])
Date: 2017-05-27 19:43:12
I’m using boost::movelib::unique_ptr with a polymorphic container of type boost::container::vector and getting a compiler error that I can’t seem to figure out (see code sample and attached compiler output). Note, this error occurs when compiling without C++11 support w/ x86-64 gcc 4.9.3. When compiling w/ C++11 support (e.g. -std=c++11) the code compiles fine. Any ideas ? Thanks in advance for any help on this.
----------------------------------------------------
#include <boost/move/unique_ptr.hpp>
#include <boost/container/vector.hpp>
class FooA
{
public:
FooA() {}
virtual ~FooA() {}
virtual void execute() {}
};
class FooB : public FooA
{
public:
FooB() {}
virtual void execute() {}
};
int main()
{
typedef boost::movelib::unique_ptr<FooA> FooAPtr;
typedef boost::movelib::unique_ptr<FooB> FooBPtr;
boost::container::vector<FooAPtr> fooVector;
FooBPtr fooBPtr(new FooB);
fooVector.push_back(boost::move(fooBPtr));
return 0;
}
<source>: In function 'int main()':
<source>:54:45: error: no matching function for call to 'boost::container::vector<boost::movelib::unique_ptr<FooA> >::push_back(boost::rv<boost::movelib::unique_ptr<FooB> >&)'
fooVector.push_back(boost::move(fooBPtr));
