Re: [Gems-users] Error loading opal

["Luo, Yan " <Yan_Luo@xxxxxxx>]

Thanks for all the replies. I just found out that the seg fault was due to my mistake (missing the configuration of ruby). 
This confirms that the previous solution indeed fixes the error of loading opal.

One minor issue about opal: It seems I cannot Ctrl-C to stop the "opal0.sim-step 10000000000" command. Is this expected?

Good work!

The segmentation is probably independent of the compilation problems you had
before.

But yes, Ruby can work without Opal no problem. When Opal is turned off,
Simics acts as a processor. You do not need Ruby if you are focusing on
memory.
