bindings and visualizer not enabled for ns3-3.33 on Linux CentOS

[Joe Pappas]

Hello,

I've had some problems with ns3 on Mac and so now am trying with a CentOS system. I have installed all of the necessary packages, but when I try to configure, I get the following output:

PyViz visualizer              : not enabled (Python Bindings are needed but not enabled)

Python Bindings               : not enabled (Python library or headers missing)

I received help before and was told to specify where my modules are installed by specifying in the command line using: 

-DPython3_LIBRARY_DIRS= 

-DPython3_INCLUDE_DIRS=  

-DPython3_EXECUTABLE=

but I get the same output. Any help on how to debug this?

Thanks,

Joe

Weird, I thought you were trying to use ns-3.38 with Cppyy bindings, but seems like I misread it.

ns-3.33 uses Pybindgen bindings, so you actually need to pip install pybindgen

and follow the older manual https://www.nsnam.org/docs/release/3.33/manual/html/python.html

Or upgrade to 3.38...

@ samikeef. Don't consider this rude please.

1. The above message doesn't seems related to the thread (read the posting guidelines), and
2. "aomdv" could be either a typo for aodv or a reference to the AOMDV protocol (a modification of AODV for multipath).

In the first case (typo), you shouldn't really need help to spot it and fix it.

In the second case you shouldn't really need try to use a protocol that is not implemented in ns-3. I mean, would you write code using a library (say boost library) without checking the manual, and just doing a best guess about what's the function name? That's a Hail Mary, at best.

There's a third case tho: that you did add a module (named aomdv) to ns-3, and that you're failing to compile and integrate it. And in this case your message is totally misleading (again, read the posting guidelines).
