Try changing the order so the libdst library is last.

"... the linker searches and processes libraries and object files in the 
order they are specified." from gcc man page and the ld man page further 
clarifies: "Normally, an archive is searched only once in the order that 
it is specified on the command line.  If a symbol in that archive is 
needed to resolve an undefined symbol referred to by an object in an 
archive that appears later on the command line, the linker would not be 
able to resolve that reference."
