    I got :

    $ Markowitz threshold set to 0.1
    Markowitz threshold set to 0.1
    QGArray::at: Absolute index 8 out of range
    Markowitz threshold set to 0.1
    OggS-SEEK: at 0 want 78328 got 68160 (diff-requested 78328)
    OggS-SEEK: at 78400 want 520 got 0 (diff-requested -77880)

    What does this mean ?

    Is "Absolute index 8 out of range" an error ?

    thanks

    As I said in the other thread: I think the "Absolute index 8 out of range" is not issued by CPLEX but some other library (my guess is Qt, in case you are using it).
    And it really looks like an error, more specifically, like you are accessing an array outside its bounds.

    Hi,

    does anybody know how to make this message go away from the screen?

    It appears that the message persists to the console despite both commands to redirect output to null
    IloCplex cplex;
    cplex.setOut(cplex.getEnv().getNullStream());
    cplex.setError(cplex.getEnv().getNullStream());
    


    thanks in advance!

    I am going to answer that one myself!

    cplex.setOut(cplex.getEnv().getNullStream());
