Build failing when trying to configure

[chandrakishorSingh]

I have configured the code using the following command as mentioned in the README of this repository.

CFLAGS="-g -O2" CXXFLAGS="-g -O2" ./waf configure --prefix=$FNCS_INSTALL --with-fncs=$FNCS_INSTALL --with-zmq=$FNCS_INSTALL --disable-python

And I got the following error.

Traceback (most recent call last):
  File "/home/chandrakishor/ns-3.26-master/.waf3-1.8.19-b1fc8f7baef51bd2db4c2971909a568d/waflib/Node.py", line 312, in ant_iter
    raise StopIteration
StopIteration

The above exception was the direct cause of the following exception:

It seems that after executing the above mentioned configure command, a new file is generated at location .waf3-1.8.19-b1fc8f7baef51bd2db4c2971909a568d/waflib/Node.py.

The statement at line 310 of this file is as follows.

                raise StopIteration

It seems this exception always gets raised as it's not followed by any try-catch block and is the last line of a function. So commenting it seems to be the easiest workaround. Hence, I've edited the line as follows.

#                raise StopIteration

As I was running short of time, I appiled this workaround to get things done. Although, a better(and preferable) approach would be to analyze why such a file is generated while configuring the repo which seems to contain wrong code.
