ARM64 + KVM configure error

sktzwhj commented 2 years ago

Describe the bug

The example app helloworld cannot be configured.

Steps to reproduce

kraft init -t helloworld hello

kraft configure -m arm64 -p kvm I also tried to give linuxu as the platform option, errors are the same.

Expected behavior

I expected the unikernel to be configured and compiled before running.

Hello! I can't seem to be able to reproduce the issue. I tried both using kraft configure -m arm64 -p kvm and selecting the platform and arch from the interactive menu as shown in the log output and it successfully configures in both cases. Can you give any extra context that would help? Could it be an issue regarding yacc, as it shows you the usage for it in the output?

I also meet this issue when running kraft configure on a kvm virtual machine. The linux distribution is CentOS 7.9. Yacc version is yacc - 1.9 20130304
