Use of undeclared identifier 'readfile'

[kyssadin]

As I understood, I was supposed to use the function from the provided 'GraphTheory.h' but it still does not work. The link provided in the code: https://github.com/JamesBremner/PathFinder The only readfile function from the provided repository only has 1 argument, but the one in code has 2 (a graph and a file)

[JamesBremner]

Sorry about that. The free function version of readfile is not fully tested so I have not yet committed to the main branch. ( The function should work used in this application ( I have been using it all day ) but I need to test that it hasn't broken anything in PathFinder )

For your convenience, I have committed it to a new branch readfile-free-function.

• Fetch the latest version of PathFinder
• Change to the new branch
• Build so76213744

[kyssadin]

Can you clarify please, how do exactly should I use the new free function? Should I simply add the new code to the other project or I need to compile it in a new project? I'm a C++ Newbie, so I need to clarify these things, maybe there're some things I don't completely understand The error I'm getting:

Looks like you are not using the makefile I provided.

[JamesBremner]

add the new code to the other project

No. Simply clone the pathfinder repo alongside the so762... repo

Like this:

[JamesBremner]

need to compile it in a new project

No. You do not need to build the PathFinder project. The so762... build will grab the code it needs from the Pathfinder clone.

[JamesBremner]

I can't assign you

Strange. Do you know why? Is there an error message?

[JamesBremner]

Are you now able to build the application?

[JamesBremner]

No answer :-(

I have added budget and interest levels to the input file. This meant that I needed a new readfile specifically for this application, so I made it a method of the cTourist class.

You still need the graph theory engine code from PathFinder.

And I still would like to know if you have been successful in building the latest version of the application which implements a complete answer to you stackoverflow question.

[JamesBremner]

I have merged the new code into PathFinder main branch. You should now build this application with PathFinder main branch checked out.
