Linux安装omnet++

1. 下载omnet++
   官方网址：https://omnetpp.org/ 现在是6.0版本
   之前版本：https://omnetpp.org/download/old
2. 终端输入 tar xvf omnetpp-5.1.1-src-linux.tgz实现解压缩
3. 终端输入cd omnetpp-5.5.1/进入解压缩后的文件下
4. 终端输入gedit ~/.bashrc
   在打开的文件中加入路径，如：export PATH=$PATH:/home/omnetpp-5.5.1/bin
5. 终端输入 source setenv 使环境变量生效
6. 终端输入./configure进行配置，无报错说明成功（错误可对照本文后面）
7. 终端输入make
8. 图标固定到启动项make install-menu-item
9. 图标固定到开始菜单栏make install-desktop-icon

其余：
INET ：https://inet.omnetpp.org/Download.html
nesting：https://gitlab.com/ipvs/nesting
ubuntu16 Desktop：http://releases.ubuntu.com/16.04/ （最好用官网的镜像，其余镜像在虚拟机运行时错误较多）

出现问题：
8. ./configure后出现 error: Bison not found, needed to build OMNeT++/OMNEST – please install it!
终端输入sudo apt-get install build-essential gcc g++ bison flex perl tcl-dev tk-dev blt libxml2-dev zlib1g-dev doxygen graphviz openmpi-bin libopenmpi-dev libpcap-dev OpenSceneGraph. osgEarth. qt5-qmake qtbase5-dev qt5-default openjdk-6-jre
若显示openjdk-6-jre未找到，安装其替换包。
若继续有错误，观察错误，查看哪个包有问题，并替换。
9. ./configure: error: Cannot build Qt apps, probably due to missing or too old Qt packages. Make sure Qt development packages are installed and newer than Qt 5.4. You can disable Qtenv by setting the WITH_QTENV variable to “no” in configure.user
终端输入 sudo apt install qt5-qmake qtbase5-dev
上述方法不行，则找到文件下的confugure.user文件，将 WITH_QTENV设置为0
11. ./configure:error:Cannot find osgEarth 2.7 or later.

sudo add-apt-repository ppa:ubuntugis/ppa
