解决过程：
cd /home/yyang/ns-allinone-2.33/otcl-1.13
sudo gedit configure.in
把77行处的
SHLIB_LD="ld -shared"
改为
SHLIB_LD="gcc -shared"
保存退出，然后
sudo gedit configure
把5518行的
SHLIB_LD="ld -shared"
改为
SHLIB_LD="gcc -shared"
保存退出，然后
cd ..
回到目录ns-allinone-2.33下运行
sudo ./install
如果正确安装可以看到提示：
--------------------------------
Please put /home/yyang/ns-allinone-2.33/bin:/home/yyang/ns-allinone-2.33/tcl8.4.18/unix:/home/yyang/ns-allinone-2.33/tk8.4.18/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.
IMPORTANT NOTICES:
(1) You MUST put /home/yyang/ns-allinone-2.33/otcl-1.13, /home/yyang/ns-allinone-2.33/lib,
into your LD_LIBRARY_PATH environment variable.
If it complains about X libraries, add path to your X libraries
into LD_LIBRARY_PATH.
If you are using csh, you can set it like:
setenv LD_LIBRARY_PATH <paths>
If you are using sh, you can set it like:
export LD_LIBRARY_PATH=<paths>
(2) You MUST put /home/yyang/ns-allinone-2.33/tcl8.4.18/library into your TCL_LIBRARY environmental
variable. Otherwise ns/nam will complain during startup.
After these steps, you can now run the ns validation suite with
cd ns-2.33; ./validate
