我想用amqpcpp CopernicaMarketingSoftware/AMQP-CPP编写一个测试程序。但编译器(g ++)抱怨:

g++版本为7.3.0,系统为ubuntu16.04amqpcpp版本为3.1.0。

我的代码如下,有3个文件,rabbitmq_handler.hrabbitmq_handler.cppmain.cc

2 个答案:

答案 0 :(得分:0)

您违反了手册中的规则:

  

构建后,使用库时需要包含两个相关文件。

+-----------+---------------+
|   File    | Include when? |
+-----------+---------------+
| amqpcpp.h |    Always     |
+-----------+---------------+

rabbitmq_handler.h 中的任何#include <amqpcpp.h>之前必须#include <amqpcpp/...>

答案 1 :(得分:0)

我不认为你已经在AMQP-CPP / include / amqpcpp / connectionhandler.h中找到了ConnectionHandler类的定义**

有时您需要包含一个包含文件,该文件本身包含您需要的所有包含文件。您需要找到该文件并将其包含在内,或者在编译之前不断添加缺少的包含文件。你有一个例子吗?它包括哪些包含文件?一个大清单或只包含其他所有内容的清单?
