Hi,
These type of issues are typically caused by an incompatible Python
version. I suspect that the build system for some reason picked up
Python 2.6, which is the default Python version prior to CentOS/RHEL 7.
IIRC, scons and gem5 usually end up using the same Python interpreter.
To build gem5 with Python 2.7 on a system that ships with Python 2.6,
you might need to explicitly run scons with Python 2.7.
Cheers,
Andreas

Hi
I'm having a hard time due to scons building errors.
Thanks in advance for your help!
I am using CentOS 6.9, gcc 4.9.2, python 2.7.12, scons 2.4.1 and swig 3.0.12.
When I install and build the gem5, the following errors occurred:
(I was typed "scons build/ARM/gem5.opt")
ext/pybind11/include/pybind11/pytypes.h: In member function 'bool
pybind11::capsule::check() const':

There are a lot of errors similar to this one.
I captured the whole screen with errors and attached it in three segments in
sequence.
I will be waiting for your answer.
Thank you.
