I've been scratching my head for days now. Gone step by step removing and adding lines and recompiling at each stage until it breaks.
ACTION act1(name nm, uint64_t amount);
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>;
The problem arises when I add act6. I had up to act4 and everything was working. So I added 5 and 6 then the error was thrown so I went back added 5 and things were still okay. Here is the error I keep getting
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" );
Appears that a name cannot contain the character '6'
, but only '1'
thru '5'
.
Action names [...] May contain: a-z, 1-5, or .
