Of course, you are working on console (in X), not on terminal ? You need to install xgraph-12.1 which you have provided in your ns-allinone-2.29.3 folder. In that folder you have readme file for installation instruction.
In further you need to add that path to environment and, if I am right, do something like this #export PATH=....../ns-allinone-2.29.3/xgraph to have xgraph working from all around. If I am wrong somebody will corect me. ----- Original Message ----- From: "jaime venzala" <[EMAIL PROTECTED]> To: <ns-users@ISI.EDU> Sent: Monday, August 14, 2006 12:11 PM Subject: [ns] problems with xgraph-12.1 > > Hello, > I am working in Fedora Core5, and I have installed ns-allinone-2.29.3. > When > I try to simulate the file example4.tcl I see this message: > > "ns: finish: couldn't execute "xgraph": no such file or directory > while executing > "exec xgraph out0.tr out1.tr out2.tr -geometry 800x400 &" > (procedure "finish" line 8) > invoked from within > "finish" > > What can I do to resolve? > > Goodbye everyone > >
