• Difficulties getting GraphViz working as a library in C++

  - by DistortedLojik

  Am working on a program that will allow a graph of nodes to be displayed and then updated visually as the nodes themselves are updated. I am fairly new to Visual Studio 2010 and am following the GraphViz guide located at http://www.graphviz.org/pdf/libguide.pdf in order to get GraphViz working as a library. I have the following code which is taken straight from the pdf linked above. #include <graphviz\gvc.h> #include <graphviz\cdt.h> #include <graphviz\graph.h> #include <graphviz\pathplan.h> using namespace std; int main(int argc, char **argv) { Agraph_t *g; Agnode_t *n, *m; Agedge_t *e; Agsym_t *a; GVC_t *gvc; /* set up a graphviz context */ gvc = gvContext(); /* parse command line args - minimally argv[0] sets layout engine */ gvParseArgs(gvc, argc, argv); /* Create a simple digraph */ g = agopen("g", AGDIGRAPH); n = agnode(g, "n"); m = agnode(g, "m"); e = agedge(g, n, m); /* Set an attribute - in this case one that affects the visible rendering */ agsafeset(n, "color", "red", ""); /* Compute a layout using layout engine from command line args */ gvLayoutJobs(gvc, g); /* Write the graph according to -T and -o options */ gvRenderJobs(gvc, g); /* Free layout data */ gvFreeLayout(gvc, g); /* Free graph structures */ agclose(g); /* close output file, free context, and return number of errors */ return (gvFreeContext(gvc)); } After compiling I get the following errors which indicate that I do not have it correctly linked. 1>main.obj : error LNK2019: unresolved external symbol _gvFreeContext referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _agclose referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _gvFreeLayout referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _gvRenderJobs referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _gvLayoutJobs referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _agsafeset referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _agedge referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _agnode referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _agopen referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _gvParseArgs referenced in function _main 1>main.obj : error LNK2019: unresolved external symbol _gvContext referenced in function _main Within the VC++ Directories I have C:\Program Files (x86)\Graphviz2.26.3\include in the Include Directories and C:\Program Files (x86)\Graphviz2.26.3\lib\release\lib in the Library Directories Any help would be greatly appreciated to help get this working. Thank you.

• Methods for implementing and using graphs of nodes in C++?

  - by DistortedLojik

  I am working on a research project that deals with social networks. I have done most of the backbone of the program in C++ and am now wanting to implement a way to create the graph of nodes and the connections as well as a way to visualize the connections between people. I have looked a little into Lemon and the Boost graph library, but was wondering which one would be easier to learn and implement or if I should just code my own.

• Libraries for visualizing graphs in real-time using C++

  - by DistortedLojik

  Are there any good C++ libraries that can be used to visualize a graph of objects that have been instantiated and have random connections to each other? I would also need it to be able to be updated in real-time so that the graph was constantly updated.

• Vector Troubles in C++

  - by DistortedLojik

  I am currently working on a project that deals with a vector of objects of a People class. The program compiles and runs just fine, but when I use the debugger it dies when trying to do anything with the PersonWrangler object. I currently have 3 different classes, one for the person, a personwrangler which handles all of the people collectively, and a game class that handles the game input and output. Edit: My basic question is to understand why it is dying when it calls outputPeople. Also I would like to understand why my program works exactly as it should unless I use the debugger. The outputPeople function works the way I intended that way. Edit 2: The callstack has 3 bad calls which are: std::vector ::begin(this=0xbaadf00d) std::vector ::size(this=0xbaadf00d) PersonWrangler::outputPeople(this=0xbaadf00d) Relevant code: class Game { public: Game(); void gameLoop(); void menu(); void setStatus(bool inputStatus); bool getStatus(); PersonWrangler* hal; private: bool status; }; which calls outputPeople where it promptly dies from a baadf00d error. void Game::menu() { hal->outputPeople(); } where hal is an object of PersonWrangler type class PersonWrangler { public: PersonWrangler(int inputStartingNum); void outputPeople(); vector<Person*> peopleVector; vector<Person*>::iterator personIterator; int totalPeople; }; and the outputPeople function is defined as void PersonWrangler::outputPeople() { int totalConnections = 0; cout << " Total People:" << peopleVector.size() << endl; for (unsigned int i = 0;i < peopleVector.size();i++) { sort(peopleVector[i]->connectionsVector.begin(),peopleVector[i]->connectionsVector.end()); peopleVector[i]->connectionsVector.erase( unique (peopleVector[i]->connectionsVector.begin(),peopleVector[i]->connectionsVector.end()),peopleVector[i]->connectionsVector.end()); peopleVector[i]->outputPerson(); totalConnections+=peopleVector[i]->connectionsVector.size(); } cout << "Total connections:" << totalConnections/2 << endl; }
