ns3中的Python编码在Ubuntu 12.04中失败

Question

I have Ubuntu 12.04 on my machine. I installed ns3 to my computer according to instructions in nsnam. I didn't get any errors up to here. I am trying to use python to run my code. I installed python 2.7.3 and ./waf --pyrun examples/first.py doesn't run. I googled a lot I couldnt find any answer why it fails. Here is the config.log for my error:

# try again with -L$python_LIBPL (some systems don't install the python library in $prefix/lib)

Answer 1

The instructions via nsnam tell you to download the source and build it: that's not the best way to do it on Ubuntu 12.04. Ubuntu 12.04 has a package all built for you:

sudo apt-get install ns3

should do the trick. No fuss at all.
