一天功夫终于知道怎么使用activeMQ的c++接口了。 花费时间最多的是不知道activemqcpp需要在activeMQ的基础上使用。
下面分别讲述activeMQ和activemqcpp的安装和使用。
一。 ActiveMQ的安装
1. 下载 源包： http://activemq.apache.org/download-archives.html
2. tar zxvf apache-activemq-xxx.bin.tar.gz -C /usr/local
3. cd apache-activemq-xxx/bin
4. chmod 755 activemq
5. 启动 ./activemq start
启动后就可以查 看： http://localhost:8161/admin, 默认 用户名和密码都是admin
二。 安装ActiveMQ-CPP
需要较多的依赖。参考 http://blog.csdn.net/lgh1700/article/details/51055784
（1）cppunit 打开http://activemq.apache.org/cms/building.html页面，这里介绍了cms build时用到的依赖库。 cppunit下载页面： https://sourceforge.net/projects/cppunit/files/cppunit/1.12.1/ 这里选择1.12.1版本，获取到下载地址后，在linux下可以用wget命令直接下载，或者下载完成后传到linux系统中。 tar解压后，进入目录，编译三部曲，configure、make、make install（install需要root权限）： ./configure --prefix=/usr/local/cppunit/ make make install 执行完后在/usr/local/cppunit/目录下可以看到头文件和库文件。 （2）apr apr的全称为Apache Portable Runtime（Apache可移植运行时），Apache旗下有很多开源软件。 apr介绍页面： http://apr.apache.org/download.cgi 这里选择最新的APR 1.5.2版本，地址为： http://mirrors.hust.edu.cn/apache//apr/apr-1.5.2.tar.gz 同上，解压进入目录，三部曲： ./configure --prefix=/usr/local/apr/ make make install （3）apr-util 这里选择最新的APR-util 1.5.4版本，下载地址为： http://mirrors.hust.edu.cn/apache//apr/apr-util-1.5.4.tar.gz 解压编译： ./configure --prefix=/usr/local/aprutil --with-apr=/usr/local/apr/ make make install （4）apr-iconv 这里选择最新的APR iconv 1.2.1版本，地址为： http://mirrors.hust.edu.cn/apache//apr/apr-iconv-1.2.1.tar.gz 解压编译： ./configure --prefix=/usr/local/apr-iconv/ --with-apr=/usr/local/apr/ make make install （5）openssl 这里选择openssl 1.0.0a版本，下载地址为： http://www.openssl.org/source/openssl-1.0.0a.tar.gz 解压编译： ./config --prefix=/usr/local/openssl/ make make install 若出现报错 cms.pod around line 457: Expected text after =item, not a number 在root权限下，执行rm -f /usr/bin/pod2man 然后重新make install （6）ActiveMQ-CPP 这里选择最新的ActiveMQ-CPP 3.9.3版本，下载页面为： http://activemq.apache.org/cms/activemq-cpp-393-release.html 解压编译： ./configure --prefix=/usr/local/ActiveMQ-CPP --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/aprutil --with-cppunit=/usr/local/cppunit --with-openssl=/usr/local/openssl make make install 这样，/usr/local/下有了ActiveMQ-CPP目录。 包含activemqcpp的头文件和lib文件
三。 示例
启动ActiveMQ，然后启动activemqcpp的代码。 再查看http://localhost:8161/admin中的queue、topic等

// Set the URI to point to the IP Address of your broker.
// add any optional params to the url to enable things like
// tightMarshalling or tcp logging etc. See the CMS web site for
// a full list of configuration options.
//
// http://activemq.apache.org/cms/
//
// Wire Format Options:
// =========================
// Use either stomp or openwire, the default ports are different for each
//
// Examples:
// tcp://127.0.0.1:61616 default to openwire
// tcp://127.0.0.1:61616?wireFormat=openwire same as above
// tcp://127.0.0.1:61613?wireFormat=stomp use stomp instead
//
// SSL:
// =========================
// To use SSL you need to specify the location of the trusted Root CA or the
// certificate for the broker you want to connect to. Using the Root CA allows
// you to use failover with multiple servers all using certificates signed by
// the trusted root. If using client authentication you also need to specify
// the location of the client Certificate.
//
// System::setProperty( "decaf.net.ssl.keyStore", "<path>/client.pem" );
// System::setProperty( "decaf.net.ssl.keyStorePassword", "password" );
// System::setProperty( "decaf.net.ssl.trustStore", "<path>/rootCA.pem" );

//
// ssl://localhost:61617

以上代码即包含了生产者又包含了消费者。 使用ifdef实现分开编译。 将以上代码做两份，分别编译生产者和消费者。
在终端1中启动生产者。 会发现8161/admin中的queue中有event_queue, 并且有消息不断入队列；
另一个终端启动消费者，可以发现消息队列中消息在被消费。
