ubuntu移植crypto++到Android平台
官方Wiki

这个移植比较简单，官方直接就有文档了，而且有现成的脚本。

将ANDROID_NDK_ROOT改成自己本机上的
有两个参数
armeabi
armeabi-v7a
armeabi-v7a-hard
arm64-v8a
mips
mips64
x86
x86_64
第二个参数
stlport (shared)
stlport-static
stlport-shared
gnu (shared)
gnu-static
gnu-shared
生成动态库和静态库
make -f GNUmakefile-cross static dynamic
最后官方的脚本
