If the function is preceeded by its fully qualified namespace then it compiles. I hope this fix does not alter the intention of the code and so can be applied readily. Patch : {{{ 62c62 < as_literal(Input), --- > ::boost::as_literal(Input), 96c96 < as_literal(Input), --- > ::boost::as_literal(Input), 127c127 < as_literal(Input), --- > ::boost::as_literal(Input), 161c161 < as_literal(Input), --- > ::boost::as_literal(Input), }}}" Patches closed Boost 1.44.0 string_algo Boost 1.37.0 Problem fixed
