ndnSIM 2.7 Compilation failed, SyntaxError: invalid syntax #92

Closed SifatTaj closed 5 years ago

SifatTaj commented 5 years ago

I am new to ndnSIM. I have been trying to compile ndnSIM 2.7 in my macOS and Linux machine. I am following the guide on http://ndnsim.net/current/getting-started.html

When I try to build without Python bindings, it compiles successfully, but with python I am getting the following error.

Traceback (most recent call last):
  File "<string>", line 3, in <module>
  File "/usr/lib/python2.7/py_compile.py", line 117, in compile
    raise py_exc
py_compile.PyCompileError:   File "/usr/local/lib/python2.7/dist-packages/visualizer/base.py", line 134
    print("Could not load plugin %r: %s" % (filename, str(ex)), file=sys.stderr)
                                                                    ^
SyntaxError: invalid syntax

Can anyone please help me fix it?

Followed the latest instructions. Still the same issue

I've fixed the issue. I had to edit the base.py file located in ndnSIM/ns-3/src/visualizer/visualizer

Change file=sys.stderr with file(sys.stderr) in line 134 and 139
