/tmp permissions issue

[gtrak]

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 :-).

[gtrak]

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

Can you run the command with --debug?

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

Can you show the stat output of your /tmp?

[Dennisman219]

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

$ stat /tmp
  File: /tmp
  Size: 12288     	Blocks: 24         IO Block: 4096   directory

And stat on the local machine?

[Dennisman219]

stat /tmp on local machine

$ stat /tmp

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

[typecasto]

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

[weidtn]

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