Hi, The question is: Do I build the AMD system differently?
gem5 does not need to be built differently on different host platforms. build/X86/base/loader/image_file_data.cc:54: panic: panic condition sz != 2 > occurred: Couldn't read magic bytes from object file This error usually shows up if there is something wrong with the elf of the binary that is being simulated (for example different ISA than the ISA gem5 binary expects). I wonder if you see the same error for other binaries/programs on the AMD system? -Ayaz On Sat, Jun 3, 2023 at 11:12 AM Beser, Nicholas D. via gem5-users < gem5-users@gem5.org> wrote: > I am working my way through the bootcamp 2022 tutorial, and I noticed > something odd.
