Appreciate your fix, I'm on MacOS 13.7.8. How would I use this to make brew install gnutls work? Greatful for any help.

Hi, @kalaws.

First of all, I need to know, did you get an error when installing GnuTLS caused during the compilation of audit.c?

Here's the error:

Last 15 lines from /Users/username/Library/Logs/Homebrew/gnutls/02.make.log:
void crau_data(struct crau_context_stack_st *stack CRAU_MAYBE_UNUSED, ...)

Alright, that's the same error I got @kalaws.

1. You must edit Homebrew's gnutls formula by running the command brew edit gnutls.
2. Add the code below before def install:

  patch do
    url "https://gist.githubusercontent.com/sptndc/ee67db7a37896bfb3fcd8b3a3666dd9c/raw/caede2f8c6f286e9694499ad065f02b3df701770/3.8.12-crau.h.patch"
    sha256 "e776e8f3022266b751d8ea1f6d87ed98f882802a17121f3837b10a03456f691b"
  end

3. Run the command with HOMEBREW_NO_INSTALL_FROM_API=1 brew install gnutls if installing for the first time or HOMEBREW_NO_INSTALL_FROM_API=1 brew upgrade gnutls if you want to update gnutls.

I hope this helps!

Thank you, worked like a charm!

Glad to hear that it fixed the installation of GnuTLS v3.8.12 for you too!

I don't suppose it was virt-viewer you were installing as well? Now I'm struggling with gstreamer complaining about SSL certificate ....

Hi @kalaws, no I didn't install it, you'd better ask in Homebrew's Discussions.
