I'm proposing patches for two problems CW 8.3 is currently having with multi_array: 1. CW 8.3 does not support the default arg in the following declaration of a member function of index_range (boost/multi_array/index_rang.hpp): index get_start(index low_index_range = index_range::from_start()) const unless index_range::from_start() has been previously declared, which has not in the current codebase. The fix consists simply in moving from_start upward inside the definition of index_range, see attached file index_range.hpp.diff. This fix is absolutely innocent and cannot break other compilers. 2. In CW 8.3, std::ptrdiff_t is *not* int, which, combined with the fact that this compiler does not support SFINAE, makes the line 243 of libs/multi_array/test/generative_tests.hpp A.reindex(1); to unintendedly resolve to a call to this overload of const_multi_array_ref: // disabled for integral types in SFINA-capable compilers template <class BaseList> void reindex(const BaseList& values); The fix consists in modifying generative_tests.hpp so as to make sure we are calling the overload of reindex taking a boost::multi_array_types::index value: #ifdef BOOST_NO_SFINAE typedef boost::multi_array_types::index index; A.reindex(index(1)); #else A.reindex(1); #endif See the attached patch file generative_tests.hpp.diff. Curiously enough, the typedef above was already defined, but not used, in the CVS version of generative_tests.hpp, which leads me to think that the author was thinking of this problem but somehow forgot about it before making effective use of the typedef. Is there any objection to these two patches being commited to the trunk and RC_1_34_0 branch? Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo 33a34,40
