[gem5-users] Error when compiling gem5

[Yuan Yao]

Hi All,



I encounter the following error when compiling gem5.



scons: done reading SConscript files.

scons: Building targets ...

[ CXX] ALPHA/sim/main.cc -> .do

In file included from ext/pybind11/include/pybind11/pytypes.h:12:0,

from ext/pybind11/include/pybind11/cast.h:13,

from ext/pybind11/include/pybind11/attr.h:13,

from ext/pybind11/include/pybind11/pybind11.h:43,

from build/ALPHA/sim/init.hh:46,

from build/ALPHA/sim/main.cc:33:

ext/pybind11/include/pybind11/detail/common.h:785:32: error: expected ';' at
end of member declaration

operator std::vector<T> &&() && { return std::move(v); }

^

ext/pybind11/include/pybind11/detail/common.h:785:37: error: expected
unqualified-id before '{' token

operator std::vector<T> &&() && { return std::move(v); }



<and many more>



Can anyone kindly give me a hint?



I am using python-2.7.2, gcc-4.8.0, and scons-2.1.0, without system root
privilege.



I guess this error has something to do with the c++11 support, since the
error is related to pybind11.



Best,

Yuan

My C++ is not that good, but move to a newer g++, 6.4 builds gem5

Hello Ciro,



Thank you for your reply.

Your way solves the problem.

I am now using GCC 6.1.0 which compiles gem5 fine.
