Hi,

I am a newbie as well, and I actually have the same problem. I am 
pretty convinced that Mike is right. I have downloaded version 2.2.7 
and version 2.0.28 and applied the quickstart procedure to both. I does 
not work with version 2.2.7.

Investigating it, I found that "SIM_hap_register_callback" is 
undeclared because its declaration is in 
simics/x86-linux/obj/include/simics/obsolete_api.h, enclosed in an 
ifdef that is not enabled by default. The condition of this ifdef looks 
like this:

if defined(SIMICS_1_4_API) || ... || defined(SIMICS_2_0_API) || 
defined(SHOW_OBSOLETE_API)
...
hap_handle_t SIM_hap_register_callback(...)
...
endif

To fix this problem, I have added -DSIMICS_2_0_API to SPECIAL_FLAGS in 
the ruby Makefile, and the compilation completes with a warning from 
simics (obsolete version is being used, or something like that). Could 
anybody tell me whether I am in the right track?

I did the same thing in the opal Makefile, but now I have a different 
error. The problem is that some mm_ functions are now deprecated in 
Simics, or are defined differently in 
simics/x86-linux/obj/include/simics/alloc.h than in 
opal/system/simdist12.C.

Here is a list of the mm_ functions for which I get errors: 
mm_new_group (deprecated), mm_malloc, mm_zalloc, mm_strdup, mm_realloc, 
mm_align (redefined).

Any thoughts on that?
Thanks,

Karin
