Android's drmserver/libdrmframework_jni.so

I found drmserver & libdrmframework_jni.so are not existing in /system/ bin/ and /system/lib/.

How to build the libdrmframewo开发者_开发问答rk_jni.so into system.img by android's make command automatically?

When I use mmm ./framework/base/drm/drmserver and mmm ./framework/base/ drm/jni, they can install correctly into system related folder.

Thanks!
