Not that I'm a great compiler/linker person, but I've need to learn a bit while maintain a Perl module built on a C++ library. The --whole-linker flag tells the compiler that *all* symbols in a library should be compiled into the shared library, and not just the ones that the compiler sees are need at compile time. This is especially useful for a perl module that is built on a C/C++ library. Hope this is a useful explanation. jas.
