hello 智能合约是官方提供的一个智能合约例子

找到config.ini中的配置项contracts-console = false 改为 true

		
[root@netkiller ~]# vim ~/.local/share/eosio/nodeos/config/config.ini

# print contract's output to console (eosio::chain_plugin)
contracts-console = true
		
		

源码

		
[root@netkiller hello]# cat /usr/local/src/eos/contracts/hello/hello.cpp 
#include <eosiolib/eosio.hpp>
using namespace eosio;

class hello : public eosio::contract {
  public:
      using contract::contract;

      /// @abi action 
      void hi( account_name user ) {
         print( "Hello, ", name{user} );
      }
};

EOSIO_ABI( hello, (hi) )		
		
		

编译智能合约

		
cd /usr/local/src/eos/build/contracts/hello
