[英]Error! constexpr variable must be initialized by a constant expression constexpr
[英]I keep getting an "error: constexpr variable 'x' must be initialized by a constant expression" from previously used working code
這幾天我一直在撓頭。 一步一步地刪除和添加行並在每個階段重新編譯,直到它中斷。
ACTION act1( name nm, uint64_t ammount );
ACTION act2(name nm, uint64_t signing_value);
ACTION receiverand(name nm, checksum256& random_value);
ACTION act4(name nm, uint64_t stake);
ACTION act5(uint64_t num);
ACTION act6(name nm);
using act1_action = action_wrapper<"act1"_n, &project::act1>;
using act2_action = action_wrapper<"act2"_n, &project::act2>;
using receiverand_action = action_wrapper<"receiverand"_n, &project::receiverand>;
using act4_action = action_wrapper<"act4"_n, &project::act4>;
using act5_action = action_wrapper<"act5"_n, &project::act5>;
using act6_action = action_wrapper<"act6"_n, &project::act6>;
當我添加act6時出現問題。 我必須采取行動4,一切正常。 所以我加了 5 和 6,然后拋出了錯誤,所以我又加了 5,一切都還好。 這是我不斷收到的錯誤
error: constexpr variable 'x' must be initialized by a constant expression
constexpr auto x =
eosio::name{std::string_view{eosio::detail::to_const_char_arr<Str...>::value,
sizeof...(Str)}};
note: in instantiation of function template specialization 'operator""_n<char, 'a',
'c', 't', '6'>' requested here
using act6_action = action_wrapper<"act6"_n, &project::act6>;
note: non-constexpr function 'check' cannot be used in a constant expression
eosio::check( false, "character is not in allowed character set for names" );
似乎名稱不能包含字符'6'
,而只能包含'1'
到'5'
。
Action names [...] May contain: az, 1-5, or.
