Hi all,
This is fixed in the gem5 repo (i.e. "non-stable"), also for gcc >= 4.6.

Subject: Re: [gem5-users] Build Error due to ptrdiff_t
If I recall correctly, I experienced this before on an older version of gem5
when using gcc 4.6.0 or higher (regardless of version of swig I think) on
Ubuntu. From the error output there, I see you're using gcc 4.6.0. Try
installing gcc 4.5.3, then changing your gcc path to it.

Hi,
After following the steps here: http://gem5.org/BBench-gem5
I attempted
scons build/ARM_FS/m5.debug
(I've cloned the gem5-stable repository)
I get the following error:

scons: *** [build/ARM_FS/python/swig/stats_wrap.do] Error 1
scons: building terminated because of errors.
Searching on this error led me to
http://www.mail-archive.com/[email protected]/msg01648.html
which led me to try adding a '#include <cstddef>>' using ptrdiff_t to
src/python/m5/SimObject.py as specified by the changes checked into source
control.
This did not fix the error when trying to build.
I'm running Python 2.7.3 and swig 1.3.34
Any thoughts?
Thanks
