sqLowLevelMFence() is low-level assembler function used in various atomic
operations.
It is not defined for ARM architecture. Can't help with it.. i know
little about ARM.
But as i told you, Dimitry already dealt with these problems when making VM work
on android platform you should just look and adopt his code.
Search mailing list , you can find pointers.

Btw, iPhone VM also runs on ARM, so the solution which Esteban/John
Macintosh found, should be similar.
I cannot say any more details, because i simply don't know.

no libm on ARM?

-lm

means that you need to find a code which uses that and remove it :)


P.S. and welcome to beautiful world of C :)
