[ns] problems with leave-group in C++ level

[jaime venzala]

Hello, I met an error as follows when I ran make in terminal in one of my 
C++ files:
Tcl::instance().evalf([{%s} set node_] leave-group {%s} 
{%d},name(),name(),groupaddr);

Error:
rccmp/rccmprecv.cc:351:error: `groupaddr´ no se declaro en este ambito.

How can I indicate the group I wnat to leave?

Thanks

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)
