Thanks a lot, Wim! I had edited the Makefile but hadn't added LD=icc there (had set it just in the shell). With that added along with "-mmic" added to the LDFLAGS and removing object files in module_cache directory fixed the problem! Now I can run on Phi!
Will post some results on performance; the translated interpreter seems much faster on Phi but I don't quite understand why! (Not that I'm complaining! ;-)
Thanks, Ajit====

Ajit,

did you edit the make file (under $TMP), or only added the above as envars?
If the former, you can check the full linker command. I'd expect problems
with the latter, as the translation (of full pypy-c anyway) runs some tests
(see platform.py).

That to me looks like the linker used was not icc (may have to set LD=icc).
What does:
$ objdump -f ./example2-c
tell you?
Best regards,
Wim
