Tool to generate an Android.mk

I have a big C++ project that has about hundred source files that are located in a bunch of sub folders. They were initially developed using Xcode IDE, so there are no makefiles there.

Now I need to build it for Android using NDK. I understand how to create Android.mk but I wonder is there any visual tool or maybe script that can do this (or at least basic structure) automatically (maybe smth. like c开发者_如何学Cmake) or do I have to do everything manually (I'll spend a lot of time for this...) ?

Well you actually can use cmake. I do so in several projects using android ndk toolchain and a modified script that I took from this project that comes from the initial port to android of OpenCV library.

If you don't want to use those scripts as a CMAKE_TOOLCHAIN_FILE (I did not want too) you can do something like:

# Setting android build
SET(CMAKE_TOOLCHAIN_FILE ${CMAKE_MODULE}/android.toolchain.cmake)
# Project name 
PROJECT (YOUR_PROJECT CXX C)

.. configure your project here

I have created a simple to script to generate Android.mk, you can see more information from here.

You can use the option -s|--scan to add all your sources in your sub folders to your LOCAL_SRC_FILES in Android.mk.
