Bristow "In the math library, file boost/math/special_functions/nonfinite_num_facets.hpp includes , but at line 144 refers to strlen without a std:: qualifier. Although g++ accepts the code, it does not conform to the requirements of the C++ standard (1998, 2003, 2011). Change needed: ------- nonfinite_num_facets.hpp ------- 144c144 < int width = (int)strlen(prefix) + (int)strlen(body); --- > int width = (int)std::strlen(prefix) + (int)std::strlen(body); g++ accepts the correct code, so there should be no compatibility issue.
