[opensuse-packaging] undefined reference at linking stage

I wonder why it is compiling well, but the linker reports an error.
Because during compile time the compiler sees a declaration for "docbParseFile" and can figure out what call to generate. However, during linking you do not have the binary artifact on the link line that provides the implementation for "docbParseFile". Therefore, the linker cannot stitch things together properly and creates an error. You'll have to figure out which library or object provides the implementation for "docbParseFile" and then add it to your link line.

The compiler only sees one file at a time. It can therefore only generate the appropriate calls to external symbols and leave the resolution up the the linker. It's up to you to find out where the symbol comes from, either another object or a library and add that to the linker call.

Besides, C++ does not really support modules, so the compiler only knows about prototypes. The existence of a real object corresponding to that prototype is never checked (except at link time, as seen in the case at hand).
