    Question XBase but examples not running.

    Hi everybody.. I just registered on this forum and on the inevitable path of learning C++ coming from the Pascal/Delphi background. I'm trying to adapt to what I'm comfortable with, one being XBase. My Op. system is Linux/Ubuntu and using both Anjuta and Netbeans. The example is sample1.cpp but it gives error messages such as below..
    I would appreciate some help.

    /home/deon/foobar-cpp4/src/main.cc:71: undefined reference to `xbXBase::xbXBase()'
    /home/deon/foobar-cpp4/src/main.cc:72: undefined reference to `xbDbf::xbDbf(xbXBase*)'
    etc...

    Install the required development packages from synaptic; this is a linker error.

    Thanks for the reply.. but I think have have installed everything possible.. what is it that I must still install? Netbeans works and so does Anjuta.. with varies tutor examples.

    If you've installed the packages, and you believe that xbXBase is defined in those packages, then you need to link the libraries with your program. There's undoubtedly a way to do that in your IDE, but I don't use it so I can't tell you where it is; look for compiler options and libraries.

    You basically need to tell the compiler/linker where to look for those functions/objects, because it isn't psychic. You haven't, and that's why it complains it can't find them.

    Thanks tabstop and Elysia for replies. Now do I edit it from the terminal or from the development programs.. because Anjuta doesn't seem to have a place where I can edit the compiler , most probably a config, and Netbeans has .. but doesn't mention a linker other than setting a path e.g /usr/lib .. /usr/include etc.

    It depends on your IDE. Note that an Editor is not an IDE. The IDE will pass on these settings to the compiler, most likely.
    As for how, you're going to have to look in the documentation for the IDE/editor/compiler you use. Look for "lib paths" or the like.

    Thanks.. I will do so. In the netbeans.. I have set a path to /usr/lib where I thought all libs should be.. in this case "libxbase.a" which is there.. put the problem does still exist.

    Ok.. I've had a good at both IDE's.. and both have paths set to where "libxbase.a" is..(/usr/lib) I've got a feeling something else is missing. Is there a way of testing if the Xbase library is functional.

    That just tells where it is, not which of the six million libraries in /usr/lib you intend to use.

    Brilliant... thanks a million.. everybody. for all the help.. It works on Netbeans but still got to see how to duplicate on Anjuta. I went to project properties, linker , library, add library but not library file, and it compiled beautifully.
