Does not build with current crystal

[AlectronikForge]

Tried to build this amazing project but unfortunately just get an error when running "make toolchain/crystal/.build/crystal" and I currently lack the knowledge to fix it..

Used crystal from Arch Linux.
Thanks for response!

I guess the best scenario would be @ffwff merging ffwff/crystal(branch lilin) with crystal-lang/crystal (master or tag 0.35.1)

For the time being you can go to toolchain/crystal and merge "crystal-lang/crystal" onto ffwff's crystal repo yourself. (You have some merge conflicts to handle, but that can be done with common sense)

I've compiled the patched crystal compiler, but am not in the perfect condition to share this :( Wish you luck and I'll get back as soon as I have the chance.

Oof never mind, the built compiler fails spectacularly...

FWIW for the next person working on this, here's the patch I made by merging:
https://gist.github.com/Scorbie/62597e651fbb09a6be7bcf1d614cc3d4
You can apply it by:

git clone https://github.com/crystal-lang/crystal
cd crystal
git checkout 0.35.1
wget -O - https://gist.githubusercontent.com/Scorbie/62597e651fbb09a6be7bcf1d614cc3d4/raw/f310c8cdc72673f43dc2c0407e438d0e54b7e866/lilith-crystal-0.35.1.patch | patch -p1
make

I think the patch is okay, the patched compiler builds okay, it's just that the compiler complains when I try to build the kernel.
The cast thing seems to have something with src/crystal/compiler/crystal/codegen/codegen.cr that uses casts.

Error: you've found a bug in the Crystal compiler. Please open an issue, including source code that will allow us to reproduce the bug: https://github.com/crystal-lang/crystal/issues
# Scorbie: I decided not to bother the crystal devs with a patched version of a previous version of the compiler.
