Hi, thank you for your interest in Latitude!

Unfortunately, it looks like you're running a fairly old version of Bison. I've been compiling against BIson 3.4.1 (from 2019) locally, and based on the copyright declaration it looks like you're running a version from 2006. I suspect the %code directive (which is unique to Bison, not a yacc holdover) was added later. Is it possible for you to get an ugpraded Bison on your machine? If you get it working, please let me know what version works with Latitude, so I can add it to the documentation. Thanks for reporting!

That's the bison that comes with OSX. There's a bunch of old software included with OSX dev tools (I'm guessing because of GPL 2 vs GPL 3 drama or something, not even sure).

Anyway, if I get one from homebrew and set the PATH to it, I get a bunch of warnings, and then this error next:

Interesting. It looks like there are some issues with Latitude when compiling with clang. You're welcome to try gcc in the meantime, but this is definitely something I'll need to look into further, as clang fails to build this repo on my machine too. Thank you for bringing this to my attention. It's very possible I'd never tried using anything other than g++ when first developing this.
