[Question][Hw3] Make does not work

[john-mai-2605]

I followed the environment setup in HW0 and execute this
eval $(opam env)

Then, when I execute make in the root, this error is reported:
can't open display
Makefile:8: recipe for target 'all' failed
make: *** [all] Error 11

I did this in the KCLOUD machine, with VS Code.

Can anyone help me pass this error

Do you use XShell?

[john-mai-2605]

No I didnt. Should I use it?

[RiceBiscuits]

Nope. Is that whole error message? Could you upload whole error message?

[john-mai-2605]

It is here

Why make asks for sudo priveleges? Hmm. I did it without sudo.

[RiceBiscuits]

I think you should find what is Error code 11.

I re-clone the repo and somehow it works now. Thanks, everyone. I'll close the issue
