Compiling ndk library

I need to compile c++ library with aosp for x86 architecture

i'm following next steps: "1 Part"

  1. $ cd <aosp_folder>
  2. $ . build/envsetup.sh
  3. $ lunch
  4. $ ln -s <droid-vnc-folder>/nativeMethods/ external/

"2 Part"

  1. $ cd external/nativeMethods
  2. $ mm .
  3. $ cd <droid-vnc-folder>
  4. $ ./updateExecsAndLibs.sh

First part is fine, but second gives me an error. The problem appears on the mm . step.

When using the mm bash function, the module may not have the required dependencies of your target. Look in the Android.mk file from the project you are trying to build and find the LOCAL_MODULE variable. Then try make <target> replacing <target> with the value from LOCAL_MODULE. This should attempt to build the required dependencies. Once the dependencies are built once then you can use mm.

Alternatively, you can build the the module with mma, that incorporates the required dependencies for that module.
