python - 如何使用 bake 安装和构建 NS-3

Question

我正在尝试通过在 Windows 7 上的 Cygwin 上键入以下命令来使用 bake 下载、构建和测试 NS-3:

$ cd
$ mkdir workspace
$ cd workspace
$ hg clone http://code.nsnam.org/bake

然后我将目录更改为 bake 目录并键入:

$ export BAKE_HOME=`pwd`
$ export PATH=$PATH:$BAKE_HOME:$BAKE_HOME/build/bin
$ export PYTHONPATH=$PYTHONPATH:$BAKE_HOME:$BAKE_HOME/build/lib

然后:

./bake.py configure -e ns-3.25

我没有在屏幕上显示任何内容然后键入:

./bake.py check

我在屏幕上显示了以下内容:

> Python - OK
> GNU C++ compiler - OK
> Mercurial - OK
> CVS - OK
> GIT - OK
> Bazaar - OK
> Tar tool - OK
> Unzip tool - OK
> Unrar tool - is missing
> 7z data compression utility - OK
> XZ data compression utility - OK
> Make - OK
> cMake - OK
> patch tool - OK
> autoreconf tool - OK

然后我在命令提示符上输入:

$ ./bake.py download

为了完成这个过程，我必须得到以下信息:

>> Downloading gccxml-ns3 (target directory:gccxml) - OK
>> Searching for system dependency python-dev - OK
>> Searching for system dependency pygraphviz - OK
>> Searching for system dependency pygoocanvas - OK
>> Searching for system dependency setuptools - OK

>> Downloading pybindgen-0.17.0.post49+ng0e4e3bc (target directory:pybindgen) - OK
>> Downloading ns-3.25 - OK

但我遇到了以下问题，我不知道如何获得所需的依赖项:

 $ ./bake.py download
 >> Searching for system dependency qt4 - OK

 > Problem: Optional dependency, module "setuptools" not available
   This may reduce the  functionality of the final build.
   However, bake will continue since "setuptools" is not an essential dependency.

Answer 1

您似乎缺少“Unrar 工具”。我这里没有要测试的 cygwin，但你可以试试:

wget http://www.rarlab.com/rar/unrarsrc-5.1.7.tar.gz
tar -xzvf unrarsrc-5.1.7.tar.gz
cd unrar
make

然后再次运行bake download。
