[gem5-dev] Re: Error in Building gem5

2020-09-13 Thread Gabe Black via gem5-dev 
That looks like a problem we've had where gem5 half uses its own local
libelf, and half uses the system one. It's been fixed on the develop branch
and will be fixed in the next release which *should* happen in the next few
weeks. I think this change should fix it on the current master branch.

2020-09-13 Thread Abhinav Sukumar Rao via gem5-dev 
As suggested by Gabe, I managed to install gem5 using CLang. However, the
hello world test program is segfaulting:
https://pastebin.com/XiZ22QkV
Is there an issue with the line that warns about the DRAM device capacity
(I doubt that it is)
Interestingly I managed to get hello32 running on SE Mode.
