windows下编译dcmtk的Android版本

1.下载最新的dcmtk http://support.dcmtk.org/redmine/attachments/download/77/dcmtk-3.6.1_20150217.tar.gz解压。

2.参照官方wiki http://support.dcmtk.org/redmine/projects/dcmtk/wiki/Howto_CompileAndroid 安装NDK、SDK、CMake、msys。

3.CMake GUI选择dcmtk目录，按照官方wiki添加ANDROID_NDK、ANDROID_SDK_ROOT选择 

android.toolchain.cmake文件。ANDROID_NATIVE_API_LEVEL选18（这个能编译过……）ANDROID_EMULATOR_AVD随便选一个模拟器。

4.修改CMake\dcmtkUseAndroidSDK.cmake的DCMTK_ANDROID_START_EMULATOR函数，直接RETURN()，不起模拟器，（因为CMake一直起不来模拟器……）

5.点击Configure、Gennerate。

6.在dcmtk的编译目录运行<msyspath>\bin\make.exe，我这提示找不到arith.h……

7.保证安装了Visual Studio，在dcmtk目录运行“cmake
.”,会默认生成VS的工程文件，再用VS打开，编译。arith.h就在config\include\dcmtk\config生成了，拷贝到ofstd\include\dcmtk\config。

8.再用<msyspath>\bin\make.exe编译，交叉编译完成！！！

9.将编译目录下lib里面需要的.a拷到NDK工程，把需要的头文件也包含进来。Application.mk添加APP_STL
:= gnustl_static，在Android.mk里面导入对应的.a。
