ActiveMQ是Apache软件基金会所研发开源的消息中间件，为应用程序提供高效的、可扩展的、稳定的和安全的企业级消息通信

Prereqs ======= These examples use the [ActiveMQ-CPP](http://activemq.apache.org/cms) C++ library, but unfortunately they don't work with the latest 3.2.4 release, you have to either wait for a subsequent release of do a source build of the project trunk. Until then, you will need to 1. [Checkout the ActiveMQ-CPP trunk source code](http://activemq.apache.org/cms/source.html) 2. [Build and Install](http://activemq.apache.org/cms/building.html) Building ======== This will vary depending on where you installed your libraries and the compiler you are using but on my Ubuntu system, I compiled the examples as follows: gcc Listener.cpp -o listener -I/usr/local/include/activemq-cpp-3.2.4 -I/usr/include/apr-1.0 -lactivemq-cpp -lstdc++ gcc Publisher.cpp -o publisher -I/usr/local/include/activemq-cpp-3.2.4 -I/usr/include/apr-1.0 -lactivemq-cpp -lstdc++ Running the Examples ==================== Note: You may need to update set an environment variable so that the activemq-cpp shared libraries can be loaded. For example on my Ubuntu system I had to add the following to my profile: export LD_LIBRARY_PATH=/usr/local/lib In one terminal window run: ./listener In another terminal window run: ./publisher You can control to which stomp server the examples try to connect to by setting the following environment variables: * `ACTIVEMQ_HOST` * `ACTIVEMQ_PORT` * `ACTIVEMQ_USER` * `ACTIVEMQ_PASSWORD`
