How can I compile the swiften XMPP library for usage with Android?

Question

I tried to compile swiften (a XMPP client library) into a lib for Android JNI but failed. Is there anyone successed? Any suggestion would be appreciated.

I compiled swiften as follow steps:

1. Downloaded swiften from http://swift.im/git/swift/commit/?id=13a3f7812520d44e374d7c391daf2128335ac067
2. Do as follow document: http://swift.im/git/swift/commit/?h=sandbox/tobias/android&id=b8e69ea59b471e1aff9c8db06aceb7108db0657b
3. since I only need swiften, so I compile as: ./scons Swiften target=android toolchain=/home/XXX/toolchain

Then I got follow problems:

1. can't find cryptlib.c, so I downloaded openssl and this fixed.
2. can't find arpa/nameser_compat.h. Then I copied this header files from /usr/include to tool-chain, and added #define BSD 199307 at the begining.
3. can't find the declarations of res_init(), res_query(), dn_expand(), dn_skipname(). So I added the declarations.

And finally I got libSwiften.a which the size is 260M. And there are about 200 link errors:
