Re: [Gems-users] undefined reference of SIM_* functions

["Mladen Nikitovic" <mladen@xxxxxxxxxxx>]

Thank you Dan, that did the trick.

I have a small follow up question - what does the assert(0) and return 0;
statements in the dummy function body actually do? Are they mandatory in
order to satisfy the compilation process?

Thanks again for the quick answer.

Regards,
Mladen

Mladen,
Part of the Ruby build process is to build the random tester, which 
links against all of ruby's code to form a standalone executable. The 
SIM_ functions are provided by Simics, and are only callable when 
running Ruby as a Simics module. When linked against the tester, we 
provide dummies of these SIM_ API calls in 
$GEMS/ruby/simics/simics_api_dummy.c. Just add a definition for your 
missing functions there, and everything should compile cleanly.

Regards,
Dan
