Unable to compile hello world about crystal HOT 4 CLOSED

We just "fixed" this. Do git pull to get the latest version of the code. Now if you compile you will get an error and a solution.

Could you try this out? I could tell you the solution, but this way we can test if the "fix" works ;-)

Sure enough:
crystal hello_world.cr:

Could not find clang. Install clang 3.3: brew tap homebrew/versions; brew install llvm33 --with-clang

clang -v

Apple LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin12.4.0
Thread model: posix

brew install llvm33 --with-clang && crystal hello_world.cr && ./hello_world

hello world!

Thank you! Also, very neat language by the way. I'm really intrigued by the global type inference!

Hopefully in the near future a post telling the ground ideas behind the type inference will appear. And magic will (partially) go away.

I'm sure one could read the paper, but a blog post distilling the basics and using layman's terms would be well received.
