Re: [Gems-users] Problem building GEMS 2.0 for x86 target

[Dan Gibson <degibson@xxxxxxxx>]

I would suggest using GEMS 2.0 and manually porting Ruby to x86. It is really not all that difficult, and the x86 patch for the prior version makes a pretty good guide.

Regards,
Dan

Hi,

I am using GEMS 2.0 with Simics 3.0.30. I was able to compile and load ruby with the target as SPARC. But when I try it for a x86 target I get the following error  in ruby/simcis/SimicsProcessor.C. I made the changes for x86 in the common/Makefile_simicsversion

 simics/SimicsProcessor.C: In member function `CacheRequestType SimicsProcessor::getRequestType(const memory_transaction_t*)':simics/SimicsProcessor.C:650: error: 'const struct x86_memory_transaction' has no member named 'address_space'
simics/SimicsProcessor.C:687: error: `SIMICS_is_ldda' was not declared in this scope
make[1]: *** [amd64-linux/generated/MOESI_CMP_token/obj/SimicsProcessor.o] Error 1
make[1]: Leaving directory `/home/simics/GEMS/gems-2.0/ruby'
make: *** [all] Error 2

I know there is a patch for SPARC to x86 target on the website, but that is under version 1.1. The files replaced by the patch are for the previous version of GEMS. Those files do not have some changes that have been made in the 2.0 version. Is there a patch for the conversion in GEMS 2.0? Or should I manually read the files in the patch and make the changes to the 2.0 version?

Please help me out with this problem.

Thank you,
