test_cypher_suites ubuntu 18.04 build failure due to lack of pthread linkage {pthread_atfork}

一个老问题,编译时出现以下错误

发现trx非object导致,查看本地代码

get_transaction_id_subcommand(CLI::App* actionRoot) {
      auto get_transaction_id = actionRoot->add_subcommand("transaction_id", localized("Get transaction id given transaction object"));
      get_transaction_id->add_option("transaction", trx_to_check, localized("The JSON string or filename defining the transaction which transaction id we want to retrieve"))->required();

      get_transaction_id->set_callback([&] {
         try {
            auto trx_var = json_from_file_or_string(trx_to_check);
            auto trx = trx_var.as<transaction>();
            std::cout << string(trx.id()) << std::endl;
         } EOS_RETHROW_EXCEPTIONS(transaction_type_exception, "Fail to parse transaction JSON '${data}'", ("data",trx_to_check))
      });
   }
};

并未做判断,怀疑版本太旧,查看github 最新代码
https://github.com/EOSIO/eos/blob/eb88d033c0abbc481b8a481485ef4218cdaa033a/programs/cleos/main.cpp#L1316

            if( trx_var.is_object() ) {  // 增加了判断
               fc::variant_object& vo = trx_var.get_object();
               // if actions.data & actions.hex_data provided, use the hex_data since only currently support unexploded data

                           maction_vo["data"] = maction_vo["hex_data"];
                           action_vo = maction_vo;
                           vo = mvo;
                        } else if( action_vo.contains( "data" ) ) {
                           if( !action_vo["data"].is_string() ) {
                              std::cerr << "get transaction_id only supports un-exploded 'data' (hex form)" << std::endl;
                              return;
                           }
                        }
                     }

                     std::cerr << "transaction json 'actions' is not an array" << std::endl;
                     return;

                  std::cerr << "transaction json does not include 'actions'" << std::endl;
                  return;

               transaction_id_type id = trx.id();

               }
            } else {
               std::cerr << "file/string does not represent a transaction" << std::endl;

         } EOS_RETHROW_EXCEPTIONS(transaction_type_exception, "Fail to parse transaction JSON '${data}'", ("data",trx_to_check))
      });

所以解决方案就是更新对应的代码,或者直接升级版本。

compile failed in 1.6.1 when using [[eosio::on_notify("*::transfer")]]

error: else expression without matching if
000035b: error: OnElseExpr callback failed

but if I use [[eosio::on_notify("eosio.token::transfer")]], compilation is success

解决

升级 eosio.cdt v1.6.2+
