> Current code will not compile with gcc 4.8. That is the default version on RH/CentOS 7.  This is needed to move to a development environment on CentOS 7.
> There is a 4.4 version of gcc available on 7. The RPM package is compat-gcc-44, I have not tried building on 7.x with older compiler, but will likely work.
> This is not urgent at this time, but we should move toward enabling a newer dev environment.  But this needs to be coordinated with with versions of OS are supported for runtime use of trafodion.
