背景是我想安装apache, ./configure 的时候他说找不到 pcre-configure

configure: error: pcre-config for libpcre not found. PCRE is required and available from
可是我用 rpm -ql  pcre 的时候，有pcre的信息，我 yum install pcre,它说我已经安装了pcre.

我的问题是：

  1.既然RPM说我已经安装了PCRE，为什么安装apache的时候又说找不到呢
  2.如果我从网上下载了 pcre, 然后 ./configure , make,  make install后，这个pcre安装后会主动记录进rpm里面吗。
     然后我 再安装apache   ./configure --with-pcre=/我安装pcre的路径，    这样子为什么就可以安装成功呢
yum install httpd can't satisfy u? why compile ur own?
     
u are the geek style, aren't u?

make sure pcre is installed properly, then during the configure of httpd, add "--with-pcre=your_pcre_path" to ./configure

if u prefer to compile everything for yourself, please get familiar with autoconf tool first.

you should always do ./configure --help to check all options...

P.S., I think yum is a pretty good package management tool. you will appreciate it if you are a real admin...
yum install pcre-devel 
就是缺了开发包，后来查明白了
带有devel是开发包，需要编译环境才需要安装。而我查到的 .so 是动态库，所以我装apache的时候需要的是开发包，而不是已经装好的库。
