Call unmanaged g++ .lib in C++/CLI - visual-studio-2010

Question

is it possible to wrap a static library which was compiled using g++ in C++/CLI?
Here is my try:
Unmanaged C++
#include <string>
class Person
{
public:
Person(void);
~Person(void);
void Print(std::string, std::string);
};
C++/CLI
#pragma once
#include <Person.h>
#pragma comment (lib, "VS-Person.lib")
//#pragma comment (lib, "GPPPerson.lib")
namespace CppWrapper {
public ref class PersonWrapper {
private:
Person* m_person;
protected:
public:
PersonWrapper(); // Doing 'm_person = new Person();'
~PersonWrapper();
};
}
The think is, when using the lib compiled in a VS2010 solution (VS-Person.lib), it works perfectly but when using the lib compiled with g++ (GPPPerson.lib), I got the following errors:
error LNK2028: jeton non résolu (0A00032D) "public: __thiscall Person::Person(void)" (??0Person##$$FQAE#XZ) référencé dans la fonction "public: __clrcall CppWrapper::PersonWrapper::PersonWrapper(void)" (??0PersonWrapper#CppWrapper##$$FQ$AAM#XZ)
error LNK2019: symbole externe non résolu "public: __thiscall Person::Person(void)" (??0Person##$$FQAE#XZ) référencé dans la fonction "public: __clrcall CppWrapper::PersonWrapper::PersonWrapper(void)" (??0PersonWrapper#CppWrapper##$$FQ$AAM#XZ)
Did I miss something?
How can I wrap an unmanaged library compiled with g++ in C++/CLI?
Thanks,

It's not possible. G++ and Visual C++ have wildly different expectations about object/library files. It's possible to recompile the unmanaged portion in Visual C++ and link to that.
Alternatively, you can build a DLL in G++ and P/Invoke that from C++/CLI.
EDIT: since it's a C++ library (as opposed to C), doubly impossible. G++ and Visual C++ won't agree on name mangling; so none of the C++ symbols would match upon linking/dynamic loading.
That said, why are you doing this in the first place? Mixing coding paradigms (managed and unmanaged, in your case) within one module is a bad idea in general. Is it really about the Person class? While I won't deny that unmanaged C++ has its charms, mixed mode projects have no charm at all.
