zeromq

今天在安装zeromq的时候费了好大的力气才算装好

下面来回顾一下在linux安装zeromq的过程

首先

http://download.zeromq.org/

1.下载最新版的zeromq

http://download.zeromq.org/zeromq-3.1.0-beta.tar.gz

2 解压

tar -xvf zeromq-3.1.0-beta.tar.gz

3 运行configure

./configure --prefix=/data/zeromq     (prefix  指定安装目录)

4. make

5. make install

6. 设置环境变量

export CPPFLAGS=-I/home/mine/0mq/include/

export LDFLAGS=-L/home/mine/0mq/lib/

7.测试代码

server.c

gcc server.c -o server -lzmq   -L/data/zeromq/lib -I/data/zeromq/include

gcc client.c -o client -lzmq   -L/data/zeromq/lib -I/data/zeromq/include

./server

./client

jzmq 是zeromq 的java客户端

下载地址

https://github.com/zeromq/jzmq/downloads

1. tar xzf zeromq-jzmq-semver-90-g58c6108.tar.gz

2. ./configure

这个时候需要上面环境变量的配置，

还需要

随便

vi /data/zeromq/.bashrc

export PATH=$PATH:/data/zeromq/include

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/data/zeromq/lib:/data/zeromq/include

只要configure 执行完毕就会生成makefile文件

3.make

4.make install
