用微软格式链接d文件及c++文件

mm: mm.obj cppnew.obj test.obj
	link $^

mm.obj: mm.d
	dmd -m32mscoff -c $^ $@

cppnew.obj: cppnew.d
	dmd -m32mscoff -c $^ $@

test.obj: test.cpp
	clang++ -o $@ -c $^ 

犯了很多错.这样就可以了.

// mm.d
extern(C++) {
  class Test {
    final this(int);
    final ~this();
    final void set(int);
    final void print();
  }
}

void main() {
  import cppnew : CPPNew;
  import cppnew : CPPDelete;

  auto test = CPPNew!Test(67);
  test.print(); // will print 67
  test.set(12);
  test.print(); // will print 12
  CPPDelete(test); // will print Destructor called
}

//test.cpp
#include <iostream>

class Test {
  public:
    Test(int);
    ~Test();
    void set(int);
    void print();
  private:
    int a;
};

Test::Test(int number) {
  set(number);
}

Test::~Test() {
  std::cout << "diaoyong xg" << std::endl;
}

void Test::set(int number) {a = number;}

void Test::print() {
  std::cout <<a<< std::endl;
}

cppnew在此.
