Description of issue

I'm trying to write a formula that builds a Racket program. It requires a racket library installed, which is normally done with raco pkg install <path to library>

If I run this command from within def install, I get an "Operation not permitted" error.

open-output-file: error opening file
  path: /opt/homebrew/opt/minimal-racket/share/racket/pkgs/.LOCKpkgs.rktd
  system error: Operation not permitted; errno=1
  context...:

If I run it from the shell outside of brew, it succeeds.

1. I'm not sure why it would be different inside brew vs outside, any ideas?

2), the available racket formula minimal-racket is deprecated due to relying on a deprecated openssl.
There is a Cask for racket, but I don't think I can install a cask from a formula, is that right?

I guess that's it for now; thanks in advance.

Brews use of the macOS sandbox to prevent software writing in other software's installation.

Not in Homebrew/core. But in a tap you can do whatever you want.

Hi @SMillerDev, thanks—

I see. Is there a Brew-approved way for installing a racket library needed to build a formula? Or can I help invent one?

Not in Homebrew/core. But in a tap you can do whatever you want.

I couldn't find docs or syntax on this, could you point me in the right direction? But also, I imagine I would run into the same sandbox restriction?

[aryairani]

Sorry, I mean I found depends_on :cask => "osxfuse" syntax, but I get this error:

Unsupported special dependency :cask

No clue about racket, but if you can install this library outside the Racket installation with some environment variables or something. That would work.

[SMillerDev]

I believe depends_on "homebrew/cask/racket" should just work. I put the full name there to be sure, it might also work with only racket.

But also, I imagine I would run into the same sandbox restriction?

Homebrew generally has no idea where casks install so it doesn't protect them

Ah hm, based on https://github.com/orgs/Homebrew/discussions/3163 (where you had previously weighed in), I didn't try it.

But with your latest message, I did try it; but it didn't work for me:

depends_on "homebrew/cask/racket" gave

Error: No available formula with the name "homebrew/cask/racket".
Please tap it and then try again: brew tap homebrew/cask

And brew tap homebrew/cask, which I'd rather avoid the users having to do, gave

Error: Tapping homebrew/cask is no longer typically necessary.
Add --force if you are sure you need it done.

And brew tap homebrew/cask --force didn't seem to help with the original depends_on.

Thanks for the help, but do you have any other ideas I could try? Or pointers to docs.

P.S. depends_on racket gives
