It would help if you showed the errors.

I don't think it is allowed to pass a temporary
to a function taking a non-const reference.

Try using

#include <iostream>

class First{

public:
     void SomeWork() const
     {
        std::cout <<"Inside SomeWork";
     }
};

class Second
{

public:
    void myfun(First const& obj)
    {
      obj.SomeWork();
    }
};

int main()
{
 Second Obj2;
 Obj2.myfun(First());
 return 0;
}
