I cloned this https://gem5.googlesource.com/public/gem5 and ran the scons build/X86/gem5.opt -j5 in the gem5 directory. I get

scons: building terminated because of errors.

A snippet of the error log: 

  In file included from build/X86/arch/x86/interrupts.hh:58,
                     from build/X86/arch/interrupts.hh:1,

OS: Archlinux 5.1.11-arch1-1-ARCH

It previously worked on my computer with the same procedure. It works on my other system(pc).

  • Thanks for the report, a few tips: 1) also provide your compiler / OS version 2) build failures are usually easy to debug and fix, have you tried? :-) 3) If it happens to not be easy, just git bisect it and email the mailing list CC the person who broke: https://stackoverflow.com/questions/4713088/how-to-use-git-bisect – Ciro Santilli Jun 24 '19 at 08:05
  • I have updated the original post to include OS version. All I have tried doing to fix is change the architecture, but to no avail. I will try emailing. – eleanor Jun 24 '19 at 10:22
