c++ code does not compile

[rfx77]

This is my code:

#include <iostream>
#include <memory>


using namespace std;

#define PROPERTY(t,n)  __declspec( property( put = property__set_##n, get = property__get_##n ) ) t n;\
        typedef t property__tmp_type_##n


#define GET(n) property__tmp_type_##n property__get_##n()
#define SET(n) void property__set_##n(const property__tmp_type_##n& value)

#define RWPROPERTY(t,n,g, s) PROPERTY(t,n);\
    GET(n) g;\
    SET(n) s;


class Test {
private:
    int val = 0;
public:
    RWPROPERTY(int, foo, {return val;}, {val = value;});
};


int main() {
    Test(test);
    test.foo = 1;

    std::cout << "val is: " << test.foo << endl;

    return 0;
}

commands for compilation:

clang++ -fdeclspec -S -emit-llvm -g main.cpp
./llvm-cbe main.ll
g++ -fpermissive main.cbe.c

The output of g++ is:

g++ -fpermissive  main.cbe.c

Maybe someone can help.

The output of CBE is C89 code, and is therefore not meant to be compiled with a C++ compiler (which is not a compatible language), and is not legal to link to a C++ stdlib (or any other existing shared libraries for that matter)
