在Ubuntu或者Debian中安装PCRE库

我需要编译一些应用程序，同时也需要Perl 5兼容正则表达式库（PCRE）。在CentOs下，我可以使用一个叫pcre-devel，但是Debian可就不一样了。我怎样在Debian/Ubuntu Linux下安装pcre-devel呢？

Perl-compatible regular expression library. PCRE has its own nativeAPI, but a set of “wrapper” functions that are based on the POSIXAPI are also supplied in the library libpcreposix. Note that thisjust provides a POSIX calling interface to PCRE: the regularexpressions themselves still follow Perl syntax and semantics. Theheader file for the POSIX-style functions is called pcreposix.h. Toinstall PCRE, type thy following command:

Perl兼容正则表达式库（PCRE）有自己原生API，但是这一系列封装函是基于POSIX API，而POSIXAPI也支持libpcreposix库。这样只要提供一个POSIX的调用接口给PCRE后，正则表达式本身仍遵循Perl的语法和语义。POSIX-style的头文件是pcreposix.h，所以，安装PCRE，需要运行以下命令。

sudo apt-get update 
sudo apt-get install libpcre3libpcre3-dev 

你可能还需要安装
sudo apt-get install openssllibssl-dev
