备注：如果没有root权限，使用 --prefix 指定安装路径
./configure --prefix=/home/work/tools/pcre-8.xx
======================================================
最近在学习nginx，nginx rewrite依赖于PCRE库，所以需要在linux系统中编译安装PCRE库。具体步骤如下：
1.下载PCRE包
首先去官网下载pcre的安装包
如果通过FTP的方式，下载地址为：ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
如果通过http的方式，下载地址为：http://sourceforge.net/projects/pcre/files/pcre/
目前最新的版本为8.32，linux对应的安装包名称为：pcre-8.32.tar.gz。
2.把安装包上传到服务器，然后解压
- [root@localhost local]# tar -zxvf pcre-8.32.tar.gz
解压之后在当前目录下生成了一个文件夹：pcre-8.32
- drwxr-xr-x 7 1169 1169 4096 Nov 30 18:50 pcre-8.32
3.配置
- [root@localhost pcre-8.32]# ./configure
配置完之后控制台会打印出pcre配置的摘要信息
- pcre-8.32 configuration summary:
-
- Install prefix .................. : /usr/local
- C preprocessor .................. : gcc -E
- C compiler ...................... : gcc
- C++ preprocessor ................ : g++ -E
- C++ compiler .................... : g++
- Linker .......................... : /usr/bin/ld
- C preprocessor flags ............ :
- C compiler flags ................ : -O2 -fvisibility=hidden
- C++ compiler flags .............. : -O2 -fvisibility=hidden -fvisibility-inlines-hidden
- Linker flags .................... :
- Extra libraries ................. :
-
- Build 8 bit pcre library ........ : yes
- Build 16 bit pcre library ....... : no
- Build 32 bit pcre library ....... : no
- Build C++ library ............... : yes
- Enable JIT compiling support .... : no
- Enable UTF-8/16/32 support ...... : no
- Unicode properties .............. : no
- Newline char/sequence ........... : lf
- \R matches only ANYCRLF ......... : no
- EBCDIC coding ................... : no
- EBCDIC code for NL .............. : n/a
- Rebuild char tables ............. : no

- POSIX mem threshold ............. : 10
- Internal link size .............. : 2

- Match limit recursion ........... : MATCH_LIMIT
- Build shared libs ............... : yes
- Build static libs ............... : yes
- Use JIT in pcregrep ............. : no
- Buffer size for pcregrep ........ : 20480

- Link pcregrep with libbz2 ....... : no
- Link pcretest with libedit ...... : no
- Link pcretest with libreadline .. : no
- Valgrind support ................ : no
- Code coverage ................... : no
4.编译
执行make操作：
- [root@localhost pcre-8.32]# make
编译完后可以执行make check进行测试（这一步非必须）
- Testing pcregrep version 8.32 2012-11-30
- Testing pcregrep main features
- Skipping pcregrep UTF-8 tests: no UTF-8 support in PCRE library
- Testing pcregrep newline settings
- PASS: RunGrepTest
- ==================
- All 5 tests passed
- ==================
- make[2]: Leaving directory `/usr/local/pcre-8.32‘
- make[1]: Leaving directory `/usr/local/pcre-8.32‘
- [root@localhost pcre-8.32]#
上面的make check结果中有一句:
- Skipping pcregrep UTF-8 tests: no UTF-8 support in PCRE library
这是因为在前面步骤中执行./configuration配置时没有加上对utf-8的支持
如果要加上对utf-8的支持可以在./configuration时加上参数：
- [root@localhost pcre-8.32]# ./configure --enable-utf8
配置完后再重新make
make完后再次执行make check结果如下：
- Testing pcregrep version 8.32 2012-11-30
- Testing pcregrep main features
- Testing pcregrep UTF-8 features
- Testing pcregrep newline settings
- PASS: RunGrepTest
- ==================
- All 5 tests passed
- ==================
- make[2]: Leaving directory `/usr/local/pcre-8.32‘
- make[1]: Leaving directory `/usr/local/pcre-8.32‘
- [root@localhost pcre-8.32]#
5.安装
执行make install操作：
- [root@localhost pcre-8.32]# make install
make install结束后pcre编译安装流程就结束了。
