Worth noting that libstdc++, whilst a separate project, is not yet feature complete.

http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#s...

OTOH libc++, the stdlib of the Clang project, is C++11 feature complete (and I guess it is the only one):

> libc++ is a 100% complete C++11 implementation on Apple's OS X.

http://libcxx.llvm.org/

The problem with libc++ the last time I tried it was that it was heavily focused on MacOS, and didn't even build out of the box on Linux.

Maybe they've fixed this by now, I dunno. [Though the wording in that blurb, "100% complete C++11 implementation on Apple's OS X" doesn't inspire confidence...]

Is the lib tied to the compiler, or are they interchangeable?

I don't know about GCC, but Clang (at least on OS X) lets you select the stdandard library with the -stdlib option. So the only question is whether you can use libc++ with GCC.

When I did research on this a year or two ago the GCC folks told me that GCC is highly coupled to libstdc++ and that it is not really interchangeable. I am not sure if this has changed more recently.

Clang definitely lets you easily switch between libstdc++ and libc++.

I can confirm you can use libc++ with gcc. I've already built a couple projects with it. It was the only way I could get past the linker step, once I included any c++11 standard library functions...

FWIW, Go 1.1 support was planned to be in GCC 4.8.1 but that has not happened and now the plan is for 4.8.2 to have it.

Is there an estimated time of arrival for 4.8.2 yet?

July 2013.

according to its release page clang 3.3 (due for release next wednesday) is also C++11 feature complete and apparently has implementations for several c++1y features already.

And perhaps more importantly, clang is the only project with a full implementation of the C++11 standard library. GCC supports the language but libstdc++ is not all the way there yet.

gcc also has various c++1y features already, although I think different ones than clang.

Neither compiler team is resting!

OT: I submitted the same news yesterday, but HN didn't pick it up:

Just 7 votes, but today this story is already on HN front page. Hmmm, may be I should've chosen a better title.

Happens all the time. It used to be worse because there wasn't a duplicate submit feature. You'd see two posts that were 20 minutes apart and the second one caught people's attention. It only takes a couple upvotes before others will take a look.

There were a HN story a few weeks ago about how to maximize the chance for front page. Some days are better than others, as well as what time of the day.

Anyone know if there are any Windows builds available for GCC 4.8.x ? I normally use TDM/MinGW but they are lagging on 4.7.2.

Also slightly off topic how is clang on Windows these days?

Here, a 4.8.0 build for 32 and 64 bits Windows:

Thanks I will check it out

There is a MinGW Windows builds sourceforge project [1]; they have already updated to 4.8.1. rubenvb's builds [2] also include 4.8.0.
