Questions about CNOT direction in IBM QX5 coupling map

Hi,

could you give us more information about the error(s) and the compiler you are using?
I just compiled the project without problems.

Regarding your issue with the direction of the CNOT gate: Did you change the architecture to to IBM QX5? (The default is Linear Nearest Neighbor and I have to admin this is not well-reflected in the documentation.)

As you told me about setting the architecture to the IBM QX5, architecture in the main code is well set up so the direction of the CNOT gate is no problem.

And the error came out like this at first,

       /home/shpark/Quantum/Bench_of_quantum_circuit/ibm_qx_mapping/src/main.cpp:108:29:   required from here

       /usr/include/c++/4.8.2/bits/stl_tree.h:140:49: error: no matching function for call to 'edge::edge(int&, int)'
           _M_value_field(std::forward<_Args>(__args)...) { }
                                                        ^

       /usr/include/c++/4.8.2/bits/stl_tree.h:140:49: error: no matching function for call to 'edge::edge(int, int&)'
           _M_value_field(std::forward<_Args>(__args)...) { }
                                                        ^

But, it seems to be because I downloaded the previous version of the git code.
There was a problem in the 'graph.emplace' part of build_graph_NN, but the latest version has been fixed so that no error occurs.

Thank you once again for everything you've done.

Happy to help :)
