This option should not be necessary; the fact that it fixes your
problem likely means that something else is wrong with your build.

You may wish to read this:
 http://www.catb.org/~esr/faqs/smart-questions.html
and ask your question again. Note that
comp.os.linux.development.system is likely more appropriate group.

The linker on Linux picks up all objects that are necessary for
the link, just as all other UNIX linkers do. To understand how
the linker decides which objects to pull out of archive libraries,
you may want to read this:

Creation of Linux shared libraries is extremely similar to creating
them on Solaris. One frequently used reference is:
 http://www.tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html

I don't particularly like that document, because (IMHO) it gives
unneccesarily-complicated recipe without explaining the what/why.

I much prefer the Solaris "Linker and Libraries Guide":
http://docs.sun.com/app/docs/doc/816-1386
