Hey,

I tried to compile the AccessExample in the examples_cxx folder of the
distribution.
I´ve compiled the all 4 build_all options of the Berkeley DB. And try to
compile the example but it will not compile. I am a newbie and have problems
understanding the errors.
I hope some of you could help me.

I use MSVC6.

I get following errors:

A nitpick: it's actually compiling fine. It's just not *linking* correctly.

You don't show or tell what exactly you did to build that program, so
I'll have to guess. From the liner error messages, by far the most
probable answer is you forgot to tell the linker to link in the
Berkeley DB libraries you just built.

Even if all the snow were burnt, ashes would remain.

Thanks! You were right. I forgot to tell the linker.
