Well, it's nice to ignore facts... Posted Aug 24, 2011 22:12 UTC (Wed) by jwakely (subscriber, #60262) [Link] There is talk of removing the dependency on RTTI from tr1::shared_ptr. But of course that will take years to be agreed on by everyone and rolled out, assuming that it goes forward.What talk exactly? You know TR1 is finished, right? It is what it is, there will be no more changes to the document. But if you want changes to libstdc++'s implementation of tr1::shared_ptr, just ask me, if it's reasonable I'll consider it. But please stop making misleading comments about C++ that ignore facts. As the bug I linked to shows, it didn't take years to agree on, it took 8 days.

And if you're *only* talking about the Android NDK version of libstdc++, I don't see why it should take years to backport a simple fix from upstream.

Hi jwakely,
I did not mean to imply that the libstdc++ maintainers were slow. However, rollout of new libstdc++ versions can be quite delayed, as you know. Using shared_ptr without exceptions on older Android versions just isn't going to compile, and it would be misleading to suggest otherwise. That was what I was trying to avoid.
Just out of curiousity, are the -fno-rtti and -fno-exceptions modes part of any standard, or just something that GCC and a few other compilers implement?
P.S. as a former C++ user, thanks for all your work on libstdc++

Sorry for misunderstanding then. The C++ standard includes RTTI and exceptions as part of the language. They're not optional, so disabling them takes you into non-standard territory (but still reasonably portable, as -fno-rtti or -fno-exceptions and their equivalents are quite common non-standard features.)
There is (or was) an "Embedded C++" dialect which omits RTTI and exceptions, among other features, but it's not a standard and as Stroustrup has said "To the best of my knowledge EC++ is dead (2004), and if it isn't it ought to be."
