今天编译varnish 报错：

checking for pkg-config... /usr/bin/pkg-config

checking pkg-config is at least version 0.9.0... yes

checking for PCRE... no

configure: error: Package requirements (libpcre) were not met:

No package 'libpcre' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you

installed software in a non-standard prefix.

Alternatively, you may set the environment variables PCRE_CFLAGS

and PCRE_LIBS to avoid the need to call pkg-config.

See the pkg-config man page for more details.

开始以为没装pcre，于是下载安装后，继续，问题依旧。安装完prce-devel后。ldconfig 都不行。后来断定是没有安装pcre-devel的问题。Centos服务器上使用yum install pcre-devel安装

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

解决。
