How to compile c++ classes in Makefile?

Question

I was making a program in c++(normally I was using an IDE to compile and everything), but this time I needed to do it without an IDE, anyway when I did Makefile to compile the program, it gave an error with something related to the class constructor

g++ -c main.cpp g++ -c graphs.cpp In file included from graphs.cpp:1:0: /usr/include/c++/5/bits/stl_construct. h: In instantiation of ' void Std::_Destroy(_Tp*) [with _Tp = Vertice]': /usr/include/c++/5/bits/stl_construct. h:103:19: required from ‘static void std::_Destroy_aux< >::__destroy(_ForwardIterator, _ForwardIterator) [with _ForwardIterator = Vertice*; bool = false]’ /usr/include/c++/5/bits/stl_construct. h:127:11: required from ' void Std::_Destroy(_Forwarditerator, _Forwarditerator) [with _Forwarditerator = Vertice*]' /usr/include/c++/5/bits/stl_construct. h:151:15: required from ‘void std::_Destroy(_ForwardIterator, _ForwardIterator, std::allocator<_T2>&) [with _ForwardIterator = Vertice*; _Tp = Vertice]’ /usr/include/c++/5/bits/stl_vector. h:424:22: required from ' Std::vector<_Tp, _Alloc>:~vector() [with _Tp = Vertice; _Alloc = Std::allocator]' graphs.cpp:3:14: required from here graphs. h:11:2: error: >Vertice::~Vertice()' is private ~Vertice(); In file included from /usr/include/c++/5/vector:62:0, from graphs. h:5, from graphs.cpp:1: /usr/include/c++/5/bits/stl_construct. h:93:7: error: Within this context { __Pointer->~_Tp(); } Makefile:15: Recipe for target 'graph. o' failed make: *** [graph. o] Error 1

I don’t know for sure what’s going on with the program,I’ve tried to get a few things out of Makefile,but still keep having this problem,Does anyone know of any solution that can make Makefile compile C++ files along with classes and constructors? Whoever can help me I thank you

OBS.:the git link of the program, in case any of you want to test to better analyze the problem https://github.com/RenanZX/Projeto2-Grafos , it can be observed that the code is empty, only classes and methods have been defined in libraries and nothing else

OBS2.:no c never had this problem,compiled without any error or anything like that, but only in the c++ that is giving this problem,and the IDE’s compile this program without any problems

Answer 1

I solved the problem (simpler than I imagined),for those who have the same problem at compilation time, <vector> is automatically destroyed when terminating the program when it is generated, so the compiler was accusing errors, because in the class Vertice there was a destroyer ~Vertice(),and the vector itself already has a destructor and this was generating a conflict at the time of compilation
