Linux下安装PCRE

PCRE（Perl Compatible Regular Expressions）是一个轻量级的Perl函数库，包括 perl 兼容的正则表达式库。它比Boost之类的正则表达式库小得多。PCRE十分易用，同时功能也很强大，性能超过了POSIX正则表达式库和一些经典的正则表达式库。1. PCRE目前最新版本为8.36，可以点这里进行下载。2. 使用tar -zxvf pcre-8.36.tar.gz进行解压。3. 运行 chmod -R 777 /pcre-8.36 对当前文件夹授予全部读写权限。4. 切换到/pcre-8.36目录下，运行 ./configure 进行pcre初始化配置，会在控制台打印出一大堆的输出信息。5. 执行make操作，进行编译。[root@server06 pcre-8.36]# make
rm -f pcre_chartables.c
ln -s ./pcre_chartables.c.dist pcre_chartables.c
make all-am
