> [name=林群凱] [time=Wed, Aug 31, 2021 8:52 PM] [color=#6F6DE5]
## 簡介
### OMNet++ 是什麼
- 物件導向的模組化網路模擬離散事件的框架
- 通用架構
- 提供編寫的基礎和工具
### OMNet++ 可以做什麼？
OMNet++ 可以用於許多領域的問題：
- 建立有線或無線網路的模型
- 通訊協定的模型
- 隊列模型
- 多處理器和分散式硬體系統
- 驗證硬體架構
- 評估軟體系統各個層面的效能
### OMNet++ 的架構
#### Network Description File (.ned)
#### Network Configuration File (.ini)
#### Source File (.cc)
## 安裝
###### 參考： [OMNeT++ Installation Guide](https://doc.omnetpp.org/omnetpp/InstallGuide.pdf), [How To Set Up OMNet++ in Ubuntu 20+](https://www.youtube.com/watch?v=oBRrhuaMxGk), [HHow To Install Omnet++ In Ubuntu 18.04.1](https://medium.com/@computerscienceengineering/omnet-3fef4875f6fb)
###### 作業系統： Ubuntu 20.04
:::warning
:warning: 注意： 不同版本的安裝有些微差異
:::
### Version 5.6.2
#### 需要的套件
先更新
```bash=
sudo apt-get update
```
安裝套件
```bash=
sudo apt-get install build-essential gcc g++ bison flex perl \
python python3 qt5-default libqt5opengl5-dev tcl-dev tk-dev \
libxml2-dev zlib1g-dev default-jre doxygen graphviz libwebkitgtk-3.0-0
```
:::info
:bulb: 如果出現 `Package 'libwebkitgtk-3.0-0' has no installation candidate`
```bash=
sudo nano /etc/apt/sources.list
```
將 `deb http://cz.archive.ubuntu.com/ubuntu bionic main universe` 加到檔案中
```bash=
sudo apt-get update
```
再安裝一次
:::
安裝額外的套件
```bash=
sudo apt-get install openscenegraph-plugin-osgearth libosgearth-dev
sudo apt-get install openmpi-bin libopenmpi-dev
```
#### 下載與解壓縮
到 https://omnetpp.org/download/ 下載 OMNeT++ 5.6.2 的 Linux 版本壓縮檔。
將檔案解壓縮
```bash=
tar xvfz omnetpp-5.6.2-src-linux.tgz
```
會產生一個子資料夾 omnetpp-5.6.2 ，將其放至於你想放置的位置。
#### 建置
到資料夾中
```bash=
cd omnetpp-5.6.1
```
設定變數
```bash=
. setenv
```
增加環境變數
```bash=
vim ~/.bashrc
```
將 `export PATH=$HOME/omnetpp-5.6.2/bin:$PATH` 加到檔案中後，重啟終端機
:::info
:bulb: 如果是使用 zsh
```bash=
source setenv
vim ~/.zshrc
```
:::
設定 OMNet++
```bash=
./configure
```
執行 make
```bash=
make
```
#### 檢查是否成功
執行範例
```bash=
cd samples/dyna
./dyna
```
選擇 small，就能看到範例程式
### Version 5.4.1
#### 需要的套件
先更新
```bash=
sudo apt-get update
```
安裝套件
```bash=
sudo apt-get install build-essential gcc g++ bison flex perl \python python3 qt5-default libqt5opengl5-dev tcl-dev tk-dev \libxml2-dev zlib1g-dev default-jre doxygen graphviz libwebkitgtk-1.0 openscenegraph-plugin-osgearth libosgearth-dev openmpi-bin libopenmpi-dev libpcap-dev gnome-color-chooser nemiver
```
:::info
:bulb: 如果出現 `Package 'libwebkitgtk-1.0' has no installation candidate`
```bash=
sudo nano /etc/apt/sources.list
```
將 `deb http://cz.archive.ubuntu.com/ubuntu bionic main universe` 加到檔案中
```bash=
sudo apt-get update
```
再安裝一次
也有可能需要改成 `libwebkitgtk-1.0-0`
:::
#### 下載與解壓縮
到 https://omnetpp.org/download/old 下載 OMNeT++ 5.4.1 的 Linux 版本壓縮檔。
將檔案解壓縮
```bash=
tar xvfz omnetpp-5.4.1-src-linux.tgz
```
會產生一個子資料夾 omnetpp-5.4.1 ，將其放至於你想放置的位置。
#### 建置
到資料夾中
```bash=
cd omnetpp-5.4.1
```
設定變數
```bash=
. setenv
```
增加環境變數
```bash=
vim ~/.bashrc
```
將 `export PATH=$HOME/omnetpp-5.4.1/bin:$PATH` 加到檔案中後，重啟終端機
:::info
:bulb: 如果是使用 zsh
```bash=
source setenv
vim ~/.zshrc
```
:::
設定 OMNet++
```bash=
./configure
```
執行 make
```bash=
make
```
:::info
:bulb: 如果在 OSG EARTH 編譯失敗，可以嘗試在設定時增加參數
```bash=
./configure WITH_OSGEARTH=no
```
在重複執行一次
###### 參考： [Unable to compile Omnet++ in Ubuntu 16.04 - make errors](https://askubuntu.com/questions/895193/unable-to-compile-omnet-in-ubuntu-16-04-make-errors)
:::
#### 檢查是否成功
執行範例
```bash=
cd samples/dyna
./dyna
```
選擇 small，就能看到範例程式
### 問題處理
#### Unknown Log format character '<'
###### 參考： [Unknown Log format character '<'](https://stackoverflow.com/questions/61497015/unknown-log-format-character)
你可能有一個就的 .qtenvrc 在主目錄的根目錄中。 嘗試：
```bash=
rm ~/.qtenvrc
```
.qtenvrc 包含 QTEnv 的各種全局初始化參數，包括提到的 logformat 參數。
#### An error has occurred. See the log file
