Thanks Michael. Follow up question:
What is the cleanest way of doing this - replacing -ansi with
-std=c++11 in %{_optflags} while using the %configure macro?
You can do it the following way, by placing this override on top of your
spec-file:
%global optflags "-std=c++11 %{optflags}"
That will override the %optflags in scope of your spec-file to carry a
prepended "-std=c++11", too. The %configure-macro will use your custom
enhanced %optflags, then.
It's also easy enough to do search and replace in %optflags if the
appending trick isn't enough. Although in this case I think it won't do
anything useful since -ansi isn't actually coming from %optflags:
%global optflags %(echo %{optflags} | sed 's/-ansi/-std=c++11/')
Also, GCC 6 that is going to land in F24 in 2 or 3 weeks is going to
switch the global default to -std=gnu++14 or -std=c++14, I've forgotten
which.
