Using STL containers in Managed C++

[Tony Nassar]

Colleagues,

Perhaps someone could advise me that this is just not possible? I'd like to
have a __nogc * std::vector<int> within a __gc class; this doesn't seem to
be possible. Do I need to manually include libc.lib in the build settings?
I've tried to put all the STL functionality in a private implementation
class that in turn aggregates the vectors (or maps, or whatever) that I
want, and call it, but then the __gc class has to call new and delete for
the implementation class. For example:

__nogc class CImpl; // I have no idea if the __nogc modifier is necessary
or desirable here!

namespace Dummy
{
public __gc class Experiment
{
public:
Experiment();
~Experiment();
private:
CImpl __nogc* m_pIml;
};

Then, of course, the .cpp file for the above class has to look like this:

#include "Impl.h"

Dummy::Experiment::Experiment()
: m_pImpl(new CImpl())
{
}

Dummy::Experiment::~Experiment()
{
delete m_pImpl;
}

I can't imagine anything simpler than this. Nonetheless I get some
mysterious link errors:

error LNK2020: unresolved token (0A000013) exception.__ctor
error LNK2020: unresolved token (0A000014) ??_7type_info@@6B@
error LNK2020: unresolved token (0A000024) exception.__dtor

What on earth does that mean? I'm sure this topic has been much discussed;
someone must know the answer.
