Bug 308

Summary:	build fails on i386 machine unless python disabled
Product:	ns-3	Reporter:	Tom Henderson <tomh>
Component:	python bindings	Assignee:	ns-bugs <ns-bugs>
Status:	RESOLVED FIXED
Severity:	normal
Priority:	P1
Version:	ns-3.2
Hardware:	All
OS:	Linux

Description Tom Henderson 2008-09-03 17:49:43 UTC

machine:  ns-old.ee.washington.edu (i386 Linux), python 2.4.3 

(unfortunately, can't access this machine or a machine that can fetch pybindgen from my current location, so I can't give more detailed error log at this time)

./waf configure --python-disable works on this machine

Comment 2 Gustavo J. A. M. Carneiro 2008-09-04 08:40:41 UTC

I suspect this "build fails with Python 2.4", because I am having such a problem:
cc1plus: warnings being treated as errors
debug/bindings/python/ns3_module_core.cc:1096: warning: deprecated conversion from string constant to ‘char*’
debug/bindings/python/ns3_module_core.cc:1306: warning: deprecated conversion from string constant to ‘char*’
debug/bindings/python/ns3_module_core.cc:1602: warning: deprecated conversion from string constant to ‘char*’
debug/bindings/python/ns3_module_core.cc:1756: warning: deprecated conversion from string constant to ‘char*’
[...]

Should be easy to fix in PyBindGen, now that I know what Python version to test...

This should be fixed now.  If it's the same bug as what is being reported here, then we can close.

Comment 4 Gustavo J. A. M. Carneiro 2008-09-05 11:55:21 UTC

OK, now should _really_ be fixed.  I tested on ns-old.ee.washington.edu, thanks to Tom giving me access.  It was a bug in Python itself (deepcopy), crazy as it sounds, so I just worked around it.
