A little work with nm *.a|grep whatever should help you figure out a better 
link order. Only you or the author of the code would have a clue about some 
of the more unusual functions you call.  If sind/cosd are what I think they 
are, they should be trivial for you to write yourself in terms of standard 
library functions.
