Oh, I'm sorry about that. It's changed now. This is what I'm getting now:

The linking continues to fail with the same two errors.
The second error is caused by shared_ptr using gcc atomic intrinsics that are not actually supported on ARM. This was discussed before on boost mailing lists, the workaround is some define making shared_ptr use pthread's mutexes -- google will tell for sure. I don't know anything about the first error. - Volodya
