    Dear Waldstein Wang,<br>
    <br>
    to be able to help you with your problem, we need some more
    information about the error you experienced.<br>
    <br>
    How did you build the VRP example? Maybe try compiling both SCIP and
    the example using `make OPT=dbg` and run `make OPT=dbg clean`
    before.<br>
    <br>
    cheers<br>
    Matthias<br>
