问题:

Is it possible to port a C++ application which uses the STL extensively to Android? I understand that currently the NDK does not support this, but is there any effort (open source or otherwise) underway to achieve this?

If not is there a way to cross compile libstdc++ for Android?

UPDATE: Ndk Revision 5 promises a default STL implementation based on STLport. http://android-developers.blogspot.com/2011/01/gingerbread-ndk-awesomeness.html Read this official NDK blog post, http://developer.android.com/sdk/ndk/index.html>and the revision notes.

回答1:

You may want to start with Dmitry Moskalchuk's modified version of the NDK (includes support for exceptions, RTTI, and the standard c++ library). Keep in mind that if you go down this path your application's size will be larger as you will be statically linking a c++ library into it. Also, this thread from the andriod-ndk group may give better direction on how to incorporate the STL.

You could always implement what you need yourself. The STL is only written using the CRT, OS headers and standard C++. It would depend on what you need done.
