Re: [Gems-users] Using Multiple CC Protocols

[Edward Lee <edwl202@xxxxxxxxx>]

Thanks for all the replies. Unfortunately, I couldn't solve the problem, I will probably do another installation for the second protocol :(

When I change the Makefile to do same "move" operations for Simics 3.0 similar to Simics 2.x, I am getting a compilation error for that part. Maybe that's the reason GEMS developers left that part of the Makefile like that. The problem is even if I do this moving *.so files manually or find a way in the Makefile, I don't think the ./modules is being looked at. My reasoning for this is, if I move not copy the ruby.so to DESTINATION folder's modules directory, Ruby is not being loaded successfully. 

Regards,

Ed

For some reason, the ruby Makefile does not do the move properly for Simics 3.x, but you can easily change that.  Just copy and adjust the steps used for 2.x to copy files into the DESTINATION directory.

I believe that the SIMICS_EXTRA_LIB step works the same for 3.x as it does for 2.x.  I switched to 3.x for my class this spring, and my students didn't report any problems with that approach.
