If to compile program with the key --pedantic-errors there exist some error messages. Otherwise everything is ok. #include //line 38 In file included from /usr/local/include/boost-1_39/boost/detail/lcast_precision.hpp:16, from /usr/local/include/boost-1_39/boost/lexical_cast.hpp:31, from accepterimpl.cpp:38: /usr/local/include/boost-1_39/boost/integer_traits.hpp:164:66: use of C99 long long integer constant /usr/local/include/boost-1_39/boost/integer_traits.hpp:164:77: use of C99 long long integer constant /usr/local/include/boost-1_39/boost/integer_traits.hpp:170:70: use of C99 long long integer constant /usr/local/include/boost-1_39/boost/integer_traits.hpp:170:70: use of C99 long long integer constant make[2]: *** [accepterimpl.o] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 Are there any means to overcome it ?
