Using Ruby 2.5.3p105 and rbgccxml 1.1.0, I get this error:

If I change GCCXML#parse to pass -std=c++14 instead of -std=c++11, the compilation succeeds.

That option could probably use a bump.
I haven't looked in a while, but do you know if there an option to always try to use the latest that the current compiler supports?
Thanks for the report, I'll take a look.

As far as I know, it’s not that easy. It’s about what standard (11, 14, 17, ...) you want to use for your source code while compiling.
