[Community] [Insight-developers] Problems building ITK against llvm libc++ (in C++11 mode)

[Sean McBride]

Hi all,

I've just tried building ITK master against llvm's libc++ (in C++11 mode):
<http://libcxx.llvm.org>

I've hit 2 errors:

1) ITK/Modules/Core/Common/src/itkProcessObject.cxx:1166:10: error: no viable conversion from 'std::__1::basic_istream<char>' to 'bool'
  return (std::istringstream(idxStr) >> idx);
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2) ITK/Modules/Core/Common/include/itkImageAlgorithm.h:24:12: fatal error: 'tr1/type_traits' file not found
#  include <tr1/type_traits>
           ^

I see that there is an #if ITK_HAS_STLTR1_TR1_TYPE_TRAITS protection, but I guess the logic needs tweaking.  It should probably prefer <type_traits> and fall back to <tr1/type_traits> only secondarily.

(I'm working on setting up a dashboard with this config.)

Cheers,
