在完全系统模式下安装gem 5时出错

Question

在gem5目录中给出下面的命令

**build/ARM/gem5.opt configs/example/fs.py --disk-image=/home/pradnya/full_system_images/aarch-system-2014-10/disks/aarch64-ubuntu-trusty-headless.img** 
gem5 Simulator System.  http://gem5.org

    raise IOError, "Can't find file '%s' on path." % filename
IOError: Can't find file 'vmlinux.aarch32.ll_20131205.0-gem5' on path**

我得到了上面的错误。请帮我一把

Answer 1

请使用以下命令设置M5_PATH环境变量：

echo "export M5_PATH=/path/to/full_system_for_gem­5/" >> ~/.bashrc

Answer 2

请注意，不再需要M5_PATH了，正如在：https://stackoverflow.com/questions/56319473/gem-5-ioerror-cant-find-a-path-to-system-files-full-system-x86-simulation-set中提到的那样，您可以显式地指向内核，这要明智得多。
