centos7.2 安装poco

下载地址: https://pocoproject.org/releases/poco-1.7.8/poco-1.7.8p3-all.tar.gz

安装：

#!/bin/sh# 安装依赖库 # yum install openssl-devel mysql++-devel# 默认方式不支持mysql #./configure --everything --omit=Data/ODBC,Data/SQLitemake -s#make -s install

具体安装时要使用什么参数，可执行 "./configure --help" 查看！

安装后，可以编写程序进行测试了。

如果程序运行时，发现找不到运行的动态库，记得将/usr/local/lib 添加到库的搜索 目录下，并执行ldconfig

以下为测试程序：main.cpp
