    Newbie, linker error, need help

    Ok now im a total newbie to programming and i have been working a program.

    This program is designed to take data from the paralel port (nothing to ambitious just a 1 or a 0) and count the cuantity of 1's recieved. That does the PCint class (PC interface)

    To then process a number of stadistics from them (the estadistical unit "Uest" takes care of it),

    To finaly show them to the user (this is done by the USERint)


    So, i have two main problems,

    The first is that when i try to compile the code (with the compiler that comes with the BLOODSHEED DEV C++) it gives me the next error:
    [Linker error] undefined reference to 'PCint::PCint(void)'
    and so on with every class

    The second is that i dont have any idea on how to recieve data from the paralel port, but this is secondary for now

    so if anyone can help me out with this i would be in debt to you

    You forgot to define the default constructor.

    Read the documentation to see what functions provide this support, if there are any.
    My best code is written with the delete key.
