从MongooseIM连接到RabbitMQ服务器

Question

我想从我的mongooseim服务器与rabbitmq服务器通信。首先，我将rabbitmq-client库（用于erlang）复制到我的apps目录中，更新了我的makefile，然后重新编译了mongooseim代码。 （根据here的说明）。这样我就可以编译没有错误的代码，并且可以看到amqp_client已从mongooseim控制台启动。现在，当我尝试从控制台运行amqp_connection：start（）时，出现以下错误。如何解决这个问题？

Answer 1

的是undef错误消息告诉我们，rabbit_net模块或connection_string功能缺失和rabbit_net是rabbit_common包的一部分。我想你没有加rabbit_common。您可以在上一个问题中粘贴的网站上找到该软件包 - here。重复步骤rabbit_common.ez，它应该工作。
