配置ubuntu17.10，ns-2.35，gcc 4.5

安裝leach-234 ------------------------------------------------------------------- 問題一：

照葫蘆畫瓢，修改makefile和makefile.in兩個檔案，如下

CC = gcc-5.4 CPP = g++-5.4 #./configure 出現tcl找不到問題，然後 ./configure --with-tcl-ver=8.5解決！ #make clean # make
make之後出現第一個錯誤！ ...... make: g++-5.4：命令未找到
Makefile:96: recipe for target 'tools/random.o' failed
make: *** [tools/random.o] Error 127
--------------------------------------------------------------
問題二：

不修改 makefile和makefile.in兩個檔案，保持兩個檔案原樣不變， # make clean # make 再次make之後出現第二個錯誤！ ...... mac/ll.cc:244:13: error: redefinition of ‘void LL::hdr_dst(Packet*, int)’
 inline void LL::hdr_dst(Packet *, int)
             ^
