MMP的，入坑NS3了，LTE是什么鬼！！！
ubantu安装NS3解决依赖环境
一堆安装包需要安装，试了N多次(CentOS没安装明白，转而ubantu)。利用脚本进行按装。
貌似得先对本机软件进行升级，从官方文档获取安装步骤，传送门：https://www.nsnam.org/wiki/Installation，官网部分安装步骤貌似不能通过（仅限本机），在安装脚本中进行说明
不得不说这安装环境的过程不是一般的长
zyb@virtual-machine:~$ uname -a

sudo apt-get install p7zip-full -y至此环境安装脚本写完，注意：仅是环境部分，祈祷不要出错吧，余下漫长的等待过程。
NS3正式安装
首先恭喜你能走到这一步，剩下的基本没什么了，完全可参照官网部分。
有多种安装方式，此处为编译安装
zyb@virtual-machine:~$ mkdir tarballs
zyb@virtual-machine:~$ cd tarballs/
zyb@virtual-machine:~/tarballs$ wget https://www.nsnam.org/release/ns-allinone-3.28.tar.bz2
zyb@virtual-machine:~/tarballs$ tar xf ns-allinone-3.28.tar.bz2
zyb@virtual-machine:~/tarballs$ cd ns-allinone-3.28/
zyb@virtual-machine:~/tarballs/ns-allinone-3.28$ ./build.py --help
Usage: build.py [options]
Options:
-h, --help show this help message and exit
--disable-netanim Don't try to build NetAnim (built by default)
--qmake-path=QMAKE_PATH
Provide absolute path to qmake executable for NetAnim
--enable-examples Do try to build examples (not built by default)
--enable-tests Do try to build tests (not built by default)
--build-options=BUILD_OPTIONS
Add these options to ns-3's "waf build" command
zyb@virtual-machine:~/tarballs/ns-allinone-3.28$ ./build.py --enable-examples --enable-tests
...此处省略N个字符
zyb@virtual-machine:~/tarballs/ns-allinone-3.28/ns-3.28$ 上述步骤执行后，ns3已成功安装，而且是3.28最新版的!
接下来进行测试，注意scratch-simulator不要带后缀。
zyb@virtual-machine:~/tarballs/ns-allinone-3.28$ cd ns-3.28/
zyb@virtual-machine:~/tarballs/ns-allinone-3.28/ns-3.28$ ./waf --run scratch/scratch-simulator
Waf: Entering directory `/home/zyb/tarballs/ns-allinone-3.28/ns-3.28/build'
Waf: Leaving directory `/home/zyb/tarballs/ns-allinone-3.28/ns-3.28/build'
Build commands will be stored in build/compile_commands.json
'build' finished successfully (5.296s)
Scratch Simulator第一次编译安装貌似得用build.by命令，一旦工程编译过想进行重新配置可用waf命令，此命令在~/tarballs/ns-allinone-3.28/ns-3.28目录中，和build.by编译工程不再同一目录
# 清除之前配置信息
zyb@virtual-machine:~/tarballs/ns-allinone-3.28/ns-3.28$ ./waf --clean
# 进行配置，默认例子和测试不便宜
zyb@virtual-machine:~/tarballs/ns-allinone-3.28/ns-3.28$ ./waf -d optimized --enable-examples --enable-tests configure
# 安装
zyb@virtual-machine:~/tarballs/ns-allinone-3.28/ns-3.28$ ./waf上述三行代码没试过，不想再在安装这墨迹了，快哭了。
