where is "build.sh" ?

It's in the source but not at the base.

Can we fix this in either case?

Hey I'll take a look at this. I'm doing a big refactor of the build code to make it a lot easier to work with but until that's ready to be shared I can fix this up. I'm also happy to take pull requests if anyone has already fixed this. Happy holidays!

[mbhatt1]

Thanks :)

This is quite an interesting way to fuzz xnu kernel. I'm interested to see if we can use protobuf grammar to fuzz other areas of xnu as well. I'll mess with it after the holidays. :D
