'is_trivially_copyable' is not a member of 'std'

[Dan Bonachea]

Building on several systems, including pcp-d-*, with g++ 4.8.5 or clang 3.4.2 results in what appears to be a similar class of error message about a missing std::is_trivially_copyable.

Are these compilers just too old to support?

If so, that's rather unfortunate as several modern Linux distros (notably openSUSE and SLES) are still shipping 4.8.5 as /usr/bin/g++.

We should at least investigate what's going on here, and impose a minimum g++ version if that's warranted.

dirac g++ 4.8.5:

I'm fairly sure 4.8 is the problem. This happened to me on older Ubuntu's until I got 4.9.

This was not implemented in GCC until version 5.1.0 (libstdc++ version 6.0.21). Clang should have full support as of version 3.3 and its associated libc++. However, as far as I can tell, libc++ is only fully supported on MacOS, so other platforms are likely using libstdc++ with Clang, in which case they need GCC 5.1.0 as well.

I am setting Component = Documentation since we've determined that the reported error reflects a requirement on the minimum compiler/STL version rather than an issue in the code.

Currently BUILD.md in develop contains the following which appears to be incorrect with respect to GCC (and incomplete w.r.t. clang and icc).

  - C++11 compiler: (gcc >= 4.9) or (clang >= ???) or (icc >= ???)

I am not sure where else we may also want/need to document these prerequisites.

I am currently pursuing this question on Linux in issue #31.

This error was caused by using a C++ standard library that we have decided is too old to support. The minimum required compiler versions are now documented in README.md and enforced by the install script.
