[ns] Installation problem

[Anirban Chakrabarti <anirban@iastate.edu>]

Hi,
I am trying to install ns 7 in Sun Solaris. I am getting the following
error while installing. I am using the ns-allinone.tar file and used the
command ./install from the ns-allinone directory.

./tcl2c++ et_tcl ../lib/tcl8.3/init.tcl  ../lib/tcl8.3/history.tcl
../lib/tcl8.3/word.tcl  ../lib/tcl8.3/http2.3/http.tcl > embedded-tcl.cc
ld.so.1: ./tcl2c++: fatal: libstdc++.so.2.10.0: open failed: No such file
or directory
*** Error code 137
make: Fatal error: Command failed for target `embedded-tcl.cc'
tclcl-1.0b10 make failed! Exiting ...
See http://www.isi.edu/nsnam/ns/ns-problems.html for problems

Any suggestions will be appreciated?
Thanks
Anirban
