Trouble with pybindgen (pybindgen missing => no python bindings)

[Henning Reich]

Hi,

I have some trouble to build ns-3 with visualizer

I can't eneable it because pybindgen are missing. 

I just follow the turorial (ns-3-tutorial.pdf) and build the first time with 

python2 ./build.py  --enable-examples --enable-tests

Now i switch into the ns-3.19 folder and run:

python2./waf configure

And that says me:

[henning@x201t-arch ns-3.19]$ python2 ./waf configure

'configure' finished successfully (3.772s)

I installed pybindgen with the system package manager, but maybe in a too recent version (0.17.0-2). 

So I hope, it's for you a simple question.

How can I use the Version, that are included in the "ns-allinone-3.19.tar.bz2" file? And can I ignore the other missing libraries? Or how i will get them? 

Thanks

Which system are you testing this on? It looks relatively recent
(gcc-4.8.2, python 3). Is python2 available?

It seems like this may be a case of incompatibility with python 3, which
the previous release doesn't support, but which there has been support
added for the forthcoming ns-3.20 release (described below):

It's my laptop with Arch Linux. It's both installed, python2.7 and python3.4. 

python is a symlink to python3.4 and python2 a symlink to python2.7. So I use "python2" as a prefix for the python-files and the general build-process works correct. (I think so)

So, If I download the ns-allinone-dev version, I can use directly python3.4? 

Thanks

I don't have an Arch or other buildslave that defaults to python3
around, so could you please let me know whether these commands work?

Instead of:
python2 ./build.py --enable-examples --enable-tests

try:
python2 ./build.py --enable-examples --enable-tests --
--with-python=/usr/bin/python2

(the '--' passes additional arguments to waf)

and

Instead of:
python2 ./waf configure

try:
python2 ./waf configure --with-python=/usr/bin/python2


In the next release, the bindings should work without requiring python2,
although generating new ones will require python2.

Thanks,
Tom

Merci, the complete line that works for me:

python2 ./waf configure --with-python=python2 --with-pybindgen=/[...]/ns-3-allinone/pybindgen/
