Linux下编译安装PCRE库
原文:http://chenzhou123520.iteye.com/blog/1817563
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
https://sourceforge.net/projects/pcre/files/pcre/
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
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

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。
