1 编写合约代码
桌面创建“hello”的文件夹，进入该文件夹，创建hello.cpp文件，粘贴下面的代码：
#include <eosiolib/eosio.hpp>
#include <eosiolib/print.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) )
2 生成.wast文件
有可能会缺少很多标准库，比如"'eosiolib/eosio.hpp' file not found",解决方法是在build文件夹下sudo make install
当上述方法处理后，也有可能提示"'stdint.h' file not found",请在tool下不要使用./eosiocpp命令，采用eosiocpp命令
