    Newbie question ...

    Good Day All,
    I have a couple of general questions regarding programming with C++ in MSVC6 on winXP.

    How does one check to see what libs the compiler links to when compiling/building a program?

    I am attempting to write some code that uses the gd library (GraphicsDraw from www.boutell.com/gd). I have downloaded the precompiled *.dll and placed it in my application directory. I am assuming that it works because I can compile/build example code. The example code creates a .png image. When I attempt to modify the code to produce a jpeg I get the following error msg :

    simplegd.obj : error LNK2001: unresolved external symbol _gdImageCreateFromJpeg

    does this mean Im not linking to the jpeg lib? How can I verfiy/ make proper adjustments?

    Any suggestions/pointers/tips etc would be greatly welcome!

    Many Thanks

    Under project properties you can check the list of libraries that are linked with.

    That would be my first guess.
    My best code is written with the delete key.
