Description Laurynas Riliskis 2009-06-30 08:59:54 UTC

ns-3.4 requires python >2.5, this can be tricky thing for RH based
machines. Since the default python is 2.4.3 and changing it to 2.5+
will brake the system (yumex etc..). Script files that are used just
uses #!/usr/bin/env python which needs to be rewritten. As well some
bindings will not work with the 2.4 version.
The installation of required python packets is really nasty then you
have 2 version.

to build when executing:
$python build.py
  File "build.py", line 96
    finally:
          ^
SyntaxError: invalid syntax

after inspecting code the try/catch syntax is from 2.5+

Comment 1 Gustavo J. A. M. Carneiro 2009-06-30 09:37:33 UTC

You're right, Python < 2.5 does not support try/except/finally in a single block, you cannot mix try/except and try/finally.
