Linux下安裝PCRE

PCRE(Perl Compatible Regular Expressions)是一個輕量級的Perl函數庫，包括 perl 兼容的正則表達式庫。它比Boost之類的正則表達式庫小得多。PCRE十分易用，同時功能也很強大，性能超過了POSIX正則表達式庫和一些經典的正則表達式庫。

1. PCRE目前最新版本為8.36，可以點這裡進行下載。

2. 使用tar -zxvf pcre-8.36.tar.gz進行解壓。

3. 運行 chmod -R 777 /pcre-8.36 對當前文件夾授予全部讀寫權限。

4. 切換到/pcre-8.36目錄下，運行 ./configure 進行pcre初始化配置，會在控制台打印出一大堆的輸出信息。

5. 執行make操作，進行編譯。

[root@server06 pcre-8.36]# make
rm -f pcre_chartables.c
ln -s ./pcre_chartables.c.dist pcre_chartables.c
make all-am

6. 運行 [root@server06 pcre-8.36]# make install，進行安裝，至此PCRE安裝完成。

[root@server06 pcre-8.36]# make install
