waiting for port connection, then shows illegal instruction

[TR174]

Hi, I tried to build crete locally. I did all the steps using the manual. When I ran crete-run, the following error shows up-
[CRETE] Waiting for port..
Illegal Instruction (Core dumped)
What should I do now? Please help out.

If memory serves, one'll get an Illegal Instruction from CRETE custom instructions executed from the Guest OS (done automatically via crete-run) if using QEMU "native" or "kvm" mode. You must rather use QEMU "interpreted" mode.

Native: crete-native-qemu-system-x86_64
Interpreted: crete-qemu-2.3-system-x86_64

I used the following command :
qemu-system-x86_64 -hda crete.img -m 2048 -k en-us
It is still showing crete-run as illegal instruction

Ensure it's crete-qemu-2.3-system-x86_64. Note the special crete- prefix derived from a CRETE-QEMU build.

If I put Crete as prefix in the host OS, it shows command not found

Assuming you've successfully built it, you'll need to get it into your $PATH, or provide a path to it. It should be in your build/bin directory.

My build/bin directory is empty although it shows total 8. Is it not built correctly?

[moralismercatus]

I don't know what you mean by "shows a total of 8" while being empty. If the binaries are not showing up in the crete-build/bin directory described as a result of this step, something isn't right with the build.

Hi, I rebuilt crete and I hope it built correctly. When I tried to invoke guest OS by using crete-qemu command, this error shows up:
