关键段落：

从 Ubuntu 12.04版本开始 aircrack-ng不再被包含在版本软件仓库中，不过我们可以从网上下载它的源代码进行编译安装。编译安装中有个小技巧，不做的话将导致编译不成功，如下：

www.linuxidc.com@linuxidc:~/aircrack-ng-1.1$ make make -C src all make[1]: Entering directory `/home/johan/aircrack-ng-1.1/src’ make -C osdep make[2]: Entering directory `/home/johan/aircrack-ng-1.1/src/osdep’ Building for Linux make[3]: Entering directory `/home/johan/aircrack-ng-1.1/src/osdep’ gcc -g -W -Wall -Werror -O3 -D_FILE_OFFSET_BITS=64 -D_REVISION=0 -fPIC -I.. -c -o osdep.o osdep.c gcc -g -W -Wall -Werror -O3 -D_FILE_OFFSET_BITS=64 -D_REVISION=0 -fPIC -I.. -c -o network.o network.c gcc -g -W -Wall -Werror -O3 -D_FILE_OFFSET_BITS=64 -D_REVISION=0 -fPIC -I.. -c -o linux.o linux.c linux.c: In function ‘is_ndiswrapper’: linux.c:165:17: error: variable ‘unused’ set but not used [-Werror=unused-but-set-variable] linux.c: In function ‘linux_set_rate’: linux.c:334:22: error: variable ‘unused’ set but not used [-Werror=unused-but-set-variable] linux.c: In function ‘linux_set_channel’: linux.c:807:22: error: variable ‘unused’ set but not used [-Werror=unused-but-set-variable] linux.c: In function ‘linux_set_freq’: linux.c:896:22: error: variable ‘unused’ set but not used [-Werror=unused-but-set-variable] linux.c: In function ‘set_monitor’: linux.c:1022:22: error: variable ‘unused’ set but not used [-Werror=unused-but-set-variable] linux.c: In function ‘do_linux_open’: linux.c:1366:12: error: variable ‘unused_str’ set but not used [-Werror=unused-but-set-variable] linux.c:1352:15: error: variable ‘unused’ set but not used [-Werror=unused-but-set-variable] linux.c: In function ‘get_battery_state’: linux.c:1982:35: error: variable ‘current’ set but not used [-Werror=unused-but-set-variable] cc1: all warnings being treated as errors make[3]: *** [linux.o] Error 1 make[3]: Leaving directory `/home/johan/aircrack-ng-1.1/src/osdep’ make[2]: *** [all] Error 2 make[2]: Leaving directory `/home/johan/aircrack-ng-1.1/src/osdep’

make[1]: *** [osd] Error 2 make[1]: Leaving directory `/home/johan/aircrack-ng-1.1/src’ make: *** [all] Error 2

下面是在 Ubuntu 12.04中编译安装 aircrack-ng的步骤 sudo apt-get install build-essential sudo apt-get install libssl-dev wget http://download.aircrack-ng.org/aircrack-ng-1.1.tar.gz tar -zxvf aircrack-ng-1.1.tar.gz cd aircrack-ng-1.1用 vi编辑器打开文件 common.mak vi common.mak找到下面这一行 CFLAGS ?= -g -W -Wall -Werror -O3去掉 “-Werror”选项，去掉后这一行如下： CFLAGS ?= -g -W -Wall -O3保存文件，接下来编译和安装 make sudo make install

按照文章所写的方法，编译成功。

P.S vi命令：

    o    插入一行

    查找：

               /keyword ：向下查找keyword匹配字符串                ?keyword：向上查找keyword匹配字符串                               n：按照同一方向继续查找               N：按照反方向查找 

              /^keyword ：  查找以keyword开头的

               /keyword$ ：  查找以keyword结尾的
