问题：在源码安装syslog-ng软件时执行./configure遇到如下报错，
require eventlog 0.2.12 ....
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
问题原因：PKG_CONFIG_PATH变量问题，安装syslog-ng前需要eventlog程序包，但是安装过程中PKG_CONFIG_PATH需要指定eventlog包地址
解决方式：执行下列命令
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/eventlog/lib/pkgconfig/
