windwos 下編譯minicap

1、參考github 介紹：https://github.com/openstf/minicap

Requirements (前提)

• NDK, Revision 10e (May 2015)
• make  （http://gnuwin32.sourceforge.net/packages/make.htm ，Setup program 會自帶依賴庫文件）
• android studio 下安裝。

•  

Building(編譯)

We include libjpeg-turbo as a Git submodule, so first make sure you've fetched it.(在minicap目錄下執行git命令，若是沒有git能夠下載。)

git submodule init  
git submodule update

You're now ready to proceed.

Building requires NDK, and is known to work with at least with NDK Revision 10e (May 2015). Older versions do not work due to the lack of .asm file support for x86_64.

Then it's simply a matter of invoking ndk-build. (最簡單的方式..\Android\sdk\ndk-bundle目錄下ndk-build.cmd)

ndk-build

You should now have the binaries available in ./libs. (執行結果所在目錄)

If you've modified the shared library, you'll also need to build that.（這個我還沒試）

Make 編譯cmd在minicap目錄下執行make。若是不熟悉make命令，能夠參考：http://www.cnblogs.com/kissfu/p/6343967.html。

makefile文件作了一些windows 系統的適應。
