[gem5-users] A build issue on RISCV gem5

[Shimomura Shigeki]

The system is Ubuntu 16.04 LTS with the latest updates on Xeon server.

The followings are what I did; I don't think I've done anything unusual:

git clone https://gem5.googlesource.com/public/gem5
git submodule update --init --recursive
scons build/RISCV/gem5.opt
[1st error here]
git pull https://gem5.googlesource.com/public/gem5 refs/changes/03/16103/3
scons build/RISCV/gem5.opt
[2nd error here]

Thanks,
Shigeki

get the following errors; could anyone take a look & let me know if there's
any workaround, what it might be? The source code is the latest.
