 This looks like typical Link problem. (the undefined reference message,
came from Linker, indeed.) . There can be some reason for this,
lib file not exist or, command line syntax... etc.

 I can't figure out what is, in your case. consult Djgpp FAQ, linker

and more. most linker error can be solved by FAQ.
