最近在学习ip分片重组，需要安装fragroute，可是网上可用的资料很少，且安装过程很麻烦，所以将自己的经验分享出来，供大家参考。

下载fragroute:https://www.monkey.org/~dugsong/fragroute/

将下载下来的压缩包解压，进入解压目录：

1：执行./configure命令：结果会报错not installed libevent、、、（原因是需要依赖这个库）

解决办法：下载libevent库http://libevent.org/，解压，进入解压目录分别执行（./configure;make,sudo make install命令）。

2：再次执行./configure命令结果如下：

sean@ubuntu:~/Software/Fragroute$ cd fragroute-1.2/ sean@ubuntu:~/Software/Fragroute/fragroute-1.2$ ./configure loading cache ./config.cache checking for a BSD compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking whether make sets ${MAKE}... yes checking for working aclocal... missing checking for working autoconf... missing checking for working automake... missing checking for working autoheader... missing checking for working makeinfo... missing checking for mawk... mawk checking for gcc... gcc checking whether the C compiler (gcc ) works... yes checking whether the C compiler (gcc ) is a cross-compiler... no checking whether we are using GNU C... yes checking whether gcc accepts -g... yes checking for a BSD compatible install... /usr/bin/install -c checking whether ln -s works... yes checking for ranlib... ranlib checking for Cygwin environment... no checking for gethostbyname... yes checking for socket... yes checking for putmsg in -lstr... no checking for libevent... yes checking for libpcap... no configure: error: libpcap not found sean@ubuntu:~/Software/Fragroute/fragroute-1.2$ 

但是会报错：

configure: error: Neither flex nor lex was found.
sean@ubuntu:~/Software/Fragroute/libpcap-1.8.1$ 

sean@ubuntu:~$ sudo apt-get install flex

configure: error: yacc is insufficient to compile libpcap.
 libpcap requires Bison,Berkeley YACC,or another YACC compatible with them.

sean@ubuntu:~$ sudo apt-get install bison

3：再次安装fragroute(./configure)

configure: error: libdnet not found 

又会报错：

fragroute.o: In function `fragroute_signal':
/home/sean/Software/Fragroute/fragroute-1.2/fragroute.c:151: undefined reference to `event_gotsig'
fragroute.o: In function `fragroute_init':

5：安装fragroute成功。

6：运行时报错：

fragroute: error while loading shared libraries: libpcap.so.1: cannot open shared object file: No such file or directory
sean@ubuntu:~/Software/Fragroute/fragroute-1.2$ fragroute

fragroute: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory
