== ns3 script incompatibility with Python 3.14 ==

On October 5, 2025, Python 3.14 was released and created an issue with the ns3 build script. If you notice an error when configuring ns-3 such as:

<pre>
$ ./ns3 configure --enable-modules=core
Traceback (most recent call last):
File "/builds/nsnam/ns-3-dev/./ns3", line 2110, in <module>

~~~~^^

parser_help.add_argument(

raise ValueError(f'action {action_name!r} is not valid for positional arguments')
ValueError: action 'store_true' is not valid for positional arguments
