Problems about ns.

[Yung-Szu Tu <yungszu@ee.ucla.edu>]

Sir/Madam,
    When I followed the instruction on the web to run some demos, there
were two problems. 
1. When I run 'test-all-simple', the error message is
ld.so.1: xgraph: fatal: libXext.so.4.10: open failed: No such file or
directory

2. When I run 'ns simple.tcl', the error message is 
ns: finish: couldn't execute "nam": no such file or directory
    while executing
"exec nam out.nam &"
    (procedure "finish" line 8)
    invoked from within
"finish"

I download the all-in-one packaged and installed it. Besides, I put the
following in my .cshrc

set path=(/w/ee.0/rubin/yungszu/ee233c/ns-allinone-2.1b5/bin $path)
setenv LD_LIBRARY_PATH
/w/ee.0/rubin/yungszu/ee233c/ns-allinone-2.1b5/otcl-1.0a4

Thanks

Sincerely,
Yung-Szu Tu
