    Problem including headers

    Ok, I'm using mySQL++ ....

    #include <mysql++>

    .. Which works fine on its own, but when I try to #include <fstream.h> ... I get 100+ errors. The main errors are "ambiguous symbol" errors. I also get syntax error : identifier and some other qweer errors.

    How can I use both these headers at the same time? I need them both

    well, i had to do:

    #include <fstream>

    ... but then fstream class constructors were different, and filebuf::sh_* 's werent available to me.

    I dont like messing with stream headers, they always cause problems.

    <fstream.h> are the old iostreams, <fstream> the new ones. They are slightly different, but better. Just look it up in a current reference.

    The constructors shouldn't be that much different. You're having trouble because you're mixing non-standard code (fstream.h) with standards-based code(mysql++ and fstream).

    The new Standard C++ Library headers don't have the .h extension, things like <iostream>, <fstream>, <string>, <list>, etc.

    The new library no longer supports sharing definitions. I don't know why, but I won't miss them.

    I never even found out what they were. Suppose I never needed them.

    Looks like it's time for me to do some research...
