Which Version do you use? 

 NIOS 10.0 EDS: you can set it under properties->nios ii application properties. There is a field called defined symbols. Put there "-d<symbol to define>" for example "-ddhcp_server".   NIOS IDE 8.1: Go to properties->c/c++ build and then choose the tab tool settings. Select Preprocessor and add your define under defined symbols.  Regards, Philipp
