Description Mathieu Lacage 2010-04-16 02:02:36 UTC

I have re-installed everything as outlined in http://www.nsnam.org/wiki/index.php/NS-3_Python_Bindings

but I still get this --python-scan error:

Comment 1 Gustavo J. A. M. Carneiro 2010-04-16 06:30:35 UTC

Sounds like a system installation problem?  Your system headers do not appear to support compilation with -m32 very well. -m32 is used as a flag to make a 64-bit system scan headers pretending to be a 32-bit system.

Comment 2 Mathieu Lacage 2010-04-17 02:05:35 UTC

I get supposedly the same errors on a stock fc12 box.

Comment 3 Gustavo J. A. M. Carneiro 2010-04-17 13:03:59 UTC

Let's check if plain g++ has the same problem.  First try to parse the header normally:

   g++ -I build/debug/ -I /usr/include/python2.6  build/debug/bindings/python/everything.h 

If it works, add -m32 and try again:

   g++ -m32 -I build/debug/ -I /usr/include/python2.6  build/debug/bindings/python/everything.h

Do you reproduce the compiler error that GCC-XML reports?

Comment 4 Josh Pelkey 2010-04-18 14:55:24 UTC

python scan worked for me on my 64-bit machine, most recent ns-3-dev: a597d6d2da85

Comment 5 Josh Pelkey 2010-04-21 12:52:48 UTC

I am closing this invalid now.  I haven't gotten it to fail yet.
