/tmp permissions issue

Open gtrak opened this issue 2 years ago • 9 comments

Trying to compile some ocaml and running into this, not sure where to begin to look.

$ outrun gary@gary-dev dune build
Error: open: /tmp/dune22fe0d.output: Permission denied

Thoughts?

I don't expect this to be fast due to i/o of lots of small files, but wanted to try it :-).

I think it's just attempting to open a read-only input stream on a temp file, which sounds pretty normal? https://github.com/ocaml/dune/blob/d75bd885262b98075299e9145a2aa3bd1a54a35d/src/dune_rules/assets.ml#L31

https://github.com/ocaml/ocaml/blob/trunk/stdlib/stdlib.ml#L409

Can you run the command with --debug?

$ outrun --debug gary@gary-dev dune build

Can you show the stat output of your /tmp?

Overv avatar May 07 '22 15:05 Overv

This is stat /tmp on the remote machine ('desktop' in 'outrun desktop make -B' from above)

And stat on the local machine?

Strange, I'll try to find the time to reproduce and investigate this.

Happening to me as well trying to compile linux, getting the following:

sudo chmod -t /tmp fixed it for me. I ran it on both host and client.
