规则表达开源库PCRE向Android下的移植步骤 window 下mingw64 gcc/g++ 4.8.1

pcre向Android下的移植 window 下mingw64 4.8.1

该编译需要在msys环境下运行，所以必须准备的环境是:

1.Android ndk (我使用的是android ndk r9b )

2.msys (http://www.mingw.org/wiki/MSYS)下载http://downloads.sourceforge.net/mingw/MSYS-1.0.11.exe。安装到d:\msys

3.下载 pcre 8.33包www.pcre.org

4.展开pcre 8.33 包pcre-8.33.zip 到d:\

 以下是步骤。

1.准备独立的android ndk toolchain,

D:\Android\android-ndk-r9b\build\tools\make-standalone-toolchain.bat --platform=android-9 --install-dir=d:\temp\my-toolchain --toolchain=arm-linux-androideabi-4.8

2.进入 msys shell 通过桌面快捷方式或者d:\msys\1.0\msys.bat都可以.

 运行mount 可以看到系统的各个盘被映射的方式 window d:盘 映射为  /d

3.将目录输入到PATH里
 export PATH=/d/temp/my-toolchina/bin:/d/msys/1.0/bin/

./configure --host=arm-linux-androideabi --prefix=G:/William_Wang/pcre-8.33 
--disable-shared --enable-newline-is-anycrlf --enable-utf8 --enable-unicode-properties

$ make #等待稍长时间后，在.libs目录下生成了.a静态库和.so后缀的动态库，由于--disable-shared禁止了动态库，所以只有.a的静态库了
$ make install 

此时在pcre-8.33目录下生成了android 命令行程序 pcretest

adb push pcretest /sdcard/temp/然后adb shell 进入超级用户后，如果手机已经root了，可以chmod 755 pcretest 权限后，直接运行。
即可。
