Lambda capture of parameter packs was added to the C++11 draft in 2010, by
https://wg21.link/cwg904 which was implemented in GCC 4.9.0 by
https://gcc.gnu.org/r202605 (so you can't do it in GCC 4.8.5).

Yes, you should use a newer compiler if you want to compile modern C++ code.

If you are using GCC 4.8.5 because you are on RHEL 7 or CentOS 7, you
should consider using GCC from a devtoolset package.
