Hi, i&#39;m using boos libraries to add some extra functions in network simulator 2,  ns-2, a network and protocols simulator, i have the version 2.34 working good with boost, but now i need to work with other version of ns2 the 2.27 version,  i modified the Makefile as in the version i have already working, but i get the error below, but i really dont know what could be the reason of it. i&#39;ll aprecciate some help, or directions for fix it. Could be something related to the boost libraries were complied using gcc-4.3 and to compile this version of ns2 i need gcc-3.2.3???do i recompile boost libraries with gcc-3.2.3 version??<br>
