Linux下編譯安裝PCRE庫
來自： http://chenzhou123520.iteye.com/blog/1817563
最近在學習nginx，nginx rewrite依賴于PCRE庫，所以需要在linux系統中編譯安裝PCRE庫。具體步驟如下：
1.下載PCRE包
首先去官網下載pcre的安裝包
如果通過FTP的方式，下載地址為：ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
如果通過http的方式，下載地址為：http://sourceforge.net/projects/pcre/files/pcre/
目前最新的版本為8.32，linux對應的安裝包名稱為：pcre-8.32.tar.gz。
2.把安裝包上傳到服務器，然后解壓
Shell代碼 
[root@localhost local]# tar -zxvf pcre-8.32.tar.gz
解壓之后在當前目錄下生成了一個文件夾：pcre-8.32
Shell代碼
drwxr-xr-x 7 1169 1169 4096 Nov 30 18:50 pcre-8.32
3.配置
Shell代碼
[root@localhost pcre-8.32]# ./configure
配置完之后控制臺會打印出pcre配置的摘要信息
Shell代碼
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

4.編譯
執行make操作：
Shell代碼
[root@localhost pcre-8.32]# make
編譯完后可以執行make check進行測試（這一步非必須）
Shell代碼
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結果中有一句:
Shell代碼
Skipping pcregrep UTF-8 tests: no UTF-8 support in PCRE library
這是因為在前面步驟中執行./configuration配置時沒有加上對utf-8的支持
如果要加上對utf-8的支持可以在./configuration時加上參數：
Shell代碼
[root@localhost pcre-8.32]# ./configure --enable-utf8
配置完后再重新make
make完后再次執行make check結果如下：
Shell代碼
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.安裝
執行make install操作：
Shell代碼
[root@localhost pcre-8.32]# make install
make install結束后pcre編譯安裝流程就結束了。
