<memory> header with clang

[L B]

I'm having trouble compiling this in clang:

#include <memory>

int main()
{
}

>clang++ -std=c++11 memory.cpp

I also get errors from <functional> in sublime-clang. I don't know how to fix this, I've never had to mess with this kind of stuff before...

Some links that talk about this:
http://mostlybuggy.wordpress.com/2012/06/06/a-unique_ptr-problem-with-clang-on-mingw/
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2012-June/021863.html

Try adding that code snippet from the second link to concurrence.h.

This also seems like it was supposed to be patched (http://gcc.gnu.org/viewcvs?view=revision&revision=188646), are you using the latest version of mingw?

Ah yeah, I seem to have both 4.6.2 and 4.7.2 and for some reason it is choosing 4.6.2 - I can't figure out how to change it so I backed up my 4.6.2 folder and made a copy of 4.7.2 as 4.6.2, and now it compiles. I'll try and figure out the proper way to do it though...

GCC versions 4.7.0 and 4.7.1 had changes to the C++ standard library which affected the ABI in C++11 mode ...
as a result C++11 code compiled with GCC 4.7.0 or 4.7.1 may be incompatible with C++11 code compiled with different GCC versions

That snippet is not relevant to me, but thanks.
