Dear you, I am quite new in NS-2, then I faced with porblem of installation of xgraph package. I have succesfully installed the required packages for ns-2.29.3, such as OTcl,ns, tk, tcl, etc, but optional package, namely xgraph-12.1. Further information, I tried to compile xgraph in Windows/cygwin environment. The problem arose when compiling is summarized as this: /usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -lX11 collect2: ld returned 1 exit status make: *** [xgraph] Error 1 Does anyone know what should I do to cope this, since almost 2 weeks I dealt with this. Thank you in advance. Best Regards Mohadig Widha R
