| Visual Studio 2012 I'm trying out the release candidate of Visual Studio 2012. tbb_exception.h does not compile due to use of std::copy_exception(). I'm having a hard time finding any info on this method. Is it really part of the std namespace? Will VS2012 be supported soon? Thanks,
Paul

| Visual Studio 2012 Hello, you are right, the issue is the same for clang (http://software.intel.com/en-us/forums/showthread.php?t=102603&o=a&s=lr), C++x0 std::copy_exception was renamed to std::make_exception_ptr
in final version of C++11 standard. So you need to either rename it in the header or define /DTBB_USE_CAPTURED_EXCEPTION=1 to not use exception_ptr like for old compilers. We are working on how is better to support both cases at once (i.e. vs2010 and vs2012).
thanks for the report

I'm trying out the release candidate of Visual Studio 2012. tbb_exception.h does not compile due to use of std::copy_exception(). I'm having a hard time finding any info on this method. Is it really part of the std namespace?
I just done verifications with different versions/editions of Visual Studio and - Visual Studio 2005 Professional Edition - 'copy_exception' is not supported - Visual Studio 2008 Express Edition - 'copy_exception' is not supported - Visual Studio 2010 Express Edition - 'copy_exception' is supported in 'exception' header file - MinGW v3.4.2 - 'copy_exception' is not supported I don't think that Microsoft will remove that support in Visual Studio 2012. |

简单解决办法（可能不规范）：
更改该.h中
tbb_exception_ptr ( const captured_exception& src ) : my_ptr(std::copy_exception(src)) {}
为
tbb_exception_ptr ( const captured_exception& src ) : my_ptr(NULL) {}
问题解决，但可能爆异常时有问题！
