ns2 2.35 (released Nov 4 2011)
下載
ns2 官網 下載 allinone 版本，解壓縮。
開始安裝
首先安裝 gcc 、 make 和 g++
1
apt install gcc g++ make
安裝 lib 你需要安裝 libxt-dev 與 libx11-dev
1
2
3
apt install libxt-dev
apt install libx11-dev
到解壓縮後的資料夾內執行 install 檔
./install
然後我遇到了以下錯誤

Makefile:93: recipe for target 'mdart/mdart_adp.o' failed
make: *** [mdart/mdart_adp.o] Error 1
Ns make failed!
我想這是 g++ 版本的問題，namespace 衝突了
找到 ./ns-2.35/mdart/mdart_adp.cc
1
vim ./ns-2.35/mdart/mdart_adp.cc
把第108行
nsaddr_t dstAdd_ = hash(reqId);
改成
nsaddr_t dstAdd_ = ::hash(reqId);
還有第396行
nsaddr_t dstAdd_ = hash(mdart_->id_);
改成
nsaddr_t dstAdd_ = ::hash(mdart_->id_);
解決
再試一次./install
然後又出事了

好吧，打開 ns-2.35/linkstate/ls.h
1
vim ns-2.35/linkstate/ls.h
第137行
void eraseAll() { erase(baseMap::begin(), baseMap::end()); }
改成
void eraseAll() { this->erase(baseMap::begin(), baseMap::end()); }
再試一次./install

…，OK，超過大小的Char
打開 ns-2.35/bitmap/play.xbm
1
vim ./ns-2.35/bitmap/play.xbm
static char play_bits[] = {
0x00, 0x00, 0x0c, 0x00, 0x3c, 0x00, 0xfc, 0x00,0xfc, 0x03, 0xfc, 0x0f,0xfc, 0x0f, 0xfc, 0x03, 0xfc, 0x00, 0x3c, 0x00, 0x0c, 0x00, 0x00, 0x00};
加上強制轉型
static char play_bits[] = {
0x00, 0x00, 0x0c, 0x00, (char)0x3c, 0x00, (char)0xfc, 0x00,(char)0xfc, 0x03, (char)0xfc, 0x0f,(char)0xfc, 0x0f, (char)0xfc, 0x03, (char)0xfc, 0x00, (char)0x3c, 0x00, 0x0c, 0x00, 0x00, 0x00};
理論上 0xfc 加上強制轉型就好，但沒關西啦~~
更新

Ns-allinone package has been installed successfully.
Here are the installation places:
tcl8.5.10: /home/aaa/Downloads/ns-allinone-2.35/{bin,include,lib}
tk8.5.10: /home/aaa/Downloads/ns-allinone-2.35/{bin,include,lib}
otcl: /home/aaa/Downloads/ns-allinone-2.35/otcl-1.14
tclcl: /home/aaa/Downloads/ns-allinone-2.35/tclcl-1.20
ns: /home/aaa/Downloads/ns-allinone-2.35/ns-2.35/ns
xgraph: /home/aaa/Downloads/ns-allinone-2.35/xgraph-12.2
gt-itm: /home/aaa/Downloads/ns-allinone-2.35/itm, edriver, sgb2alt, sgb2ns, sgb2comns, sgb2hierns
----------------------------------------------------------------------------------
Please put /home/aaa/Downloads/ns-allinone-2.35/bin:/home/aaa/Downloads/ns-allinone-2.35/tcl8.5.10/unix:/home/aaa/Downloads/ns-allinone-2.35/tk8.5.10/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.
IMPORTANT NOTICES:
(1) You MUST put /home/aaa/Downloads/ns-allinone-2.35/otcl-1.14, /home/aaa/Downloads/ns-allinone-2.35/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/aaa/Downloads/ns-allinone-2.35/tcl8.5.10/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-2.35; ./validate
For trouble shooting, please first read ns problems page
http://www.isi.edu/nsnam/ns/ns-problems.html. Also search the ns mailing list archive
for related posts.
看到這些就算成功了，但還沒結束

source ~/.bashrc 重整一下
測試 ns 命令
如果看到 “%” 就大功告成了

- 為甚麼不裝低版本的 gcc 和 g++
也可以，我試過裝 4.8 版本的 gcc 和 g++，但要改Makefile
