Wed May 12 02:32:07 PDT 2004

hi,all
I added  .cc and .h file to the directory 'queue'.
Then, I added the .o module to the Makefile file in directory 'ns' 
And I try to rebuild the ns by typing 'make depend' and 'make', howerver, it
doesn't work.
And I also try to rebuild ns by change the configure.in file, then './configure',
then 'make', and it also doesn't work.

can anybody help me ?? thanks a lot.
