How modified brew Formulae for Libvmaf in Mac os BigSur

Question

I have an error installing the libvmaf dependency in mac OS BigSur.

Here is the error when installing with:

brew install libvmaf

Error : unknown type name 'size_t'

This error occurs when the formulae executes this command:

system "ninja", "-vC", "build"

Part of the solution is to add #include <stddef.h> at the beginning of its C files, then continue compiling.

However, if you use: brew install libvmaf, brew will recompile with the original formulae, and the error will still occur.

To run another formulae, issue this command: brew install /pathFile/libvmaf.rb

Except that I can't modify the original formulae so that it uses a pre-compiled folder (the one without errors).

Here's the original libvmaf formulae:

I am working on this myself. It looks like there was a breaking change somewhere (maybe in a vim update?). I think it is related to this. https://github.com/orgs/Homebrew/discussions/5093

Ahhhh Ok I think I got a fix for you!!!!

So it WAS a breaking change in vim that was causing this with a patch that was put out 5 days ago to fix this. 9.1.0052.

if you run vim --version it will give you a breakdown of your version. version 9.1 ...... Included patches: 1-50 <- needs to be at least 1-52.

brew for some reason would not grab any patches after 9.1.0050 when I would run brew update vim. If you unlink vim and then install the newest version this should fix your issue. Try running

brew unlink vim   
brew install --HEAD vim

Then check your vim --version again and you should have upgraded. Then brew install libvmaf and you should be g2g.
