本文介绍如何通过修改Makefile文件配置并使用GDB工具来调试NS-2网络模拟软件，包括设置断点、运行调试等关键步骤。

确定gdb安装没有问题，解决方法：

1. 修改makefile.in：加上-g3选项
.cc.o:
   @rm -f $@
   $(CPP) -g3 -c $(CFLAGS) $(INCLUDES) -o $@ $*.cc

.c.o:
   @rm -f $@
   $(CC) -g3 -c $(CFLAGS) $(INCLUDES) -o $@ $*.c
2. 修改Makefile(没有任何后缀的)将里面
CCOPT = -Wall  -Wno-write-strings

STATIC =
LDFLAGS = $(STATIC)
LDOUT = -o $(BLANK)
改变为：
CCOPT = -Wall -g -Wno-write-strings（就改这一个地方）
STATIC =
LDFLAGS = $(STATIC)
LDOUT = -o $(BLANK)

3. 在ns-allinone-2.34/ns-2.34目录下重新编译
make clean
make

4. 成功后开始调试：
转到ns-2.34目录下，cd ~/ns-allinone-2.34/ns-2.34/
gdb ns

设置断点：

(gdb) b aodv.cc:559
Breakpoint 1 at 0x82d058e: file aodv/aodv.cc, line 559.

运行：
(gdb) r wireless-flooding.tcl
Starting program: /home/hanwei/ns-allinone-2.34/bin/ns wireless-flooding.tcl
num_nodes is set 24
INITIALIZE THE LIST xListHead

Breakpoint 1, AODV::recv (this=0x8ebe150, p=0x93445c8) at aodv/aodv.cc:559
559 AODV::recv(Packet *p, Handler*) {
Current language: auto; currently c++

接下来就可以调试了哦~
