linux zeromq

本人在centos下安装zeromq

1.下载最新版的zeromq
http://download.zeromq.org/
2 解压

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

3 运行configure

./configure --prefix=/data/zeromq PKG_CONFIG_PATH="/data/sodium/lib/pkgconfig/" (prefix 指定安装目录)

　出现问题：

configure: error: Package requirements (libsodium >= 0.0.0) were not met

参考： http://www.cnblogs.com/jim-hwg/p/4952349.html[/code] 　这里最好使用

libsodium-1.0.3 小于等于版本。
cd /home/shengkaishan/software/libsodium-1.0.3
./configure --prefix=/data/sodium
make
make install

4. make

5. make install
