varnish-3.0.6安裝問題

checking for getaddrinfo in -lnsl... 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.

但明明裝了pcre的了，怎麼checking for PCRE時還是返回No呢？

baidu了半天，答案都是千篇一律配置PKG_CONFIG_PATH環境變量，試了半天都不行。

再仔細看看報錯，如果不配置PKG_CONFIG_PATH環境變量，可以直接配置PCRE_CFLAGS和PCRE_LIBS這兩個環境變量。

於是直接export PCRE_CFLAGS=`pcre-config --cflags`和export PCRE_LIBS=`pcre-config --libs`

再configure，通過！

再次證明，baidu果然坑爹~
