Oro!

Welcome to Crystal!

Did you try googling "llc: : Invalid MODULE_CODE_GLOBALVAR record"? I found a bunch of results saying that you probably have many LLVM versions installed so two llvm command are executed with different versions (crystal uses first llc, then clang). So the problem is not related to crystal.

What's the output of the following commands?

llc -version
clang --version

Anyway, make sure that on the command line when you execute any llvm executable they are using version 3.1.

llc -version

Low Level Virtual Machine (http://llvm.org/):
  llvm version 2.9 (Ubuntu 2.9+dfsg-3ubuntu4)
...

clang --version

Ubuntu clang version 3.0-6ubuntu3 (tags/RELEASE_30/final) (based on LLVM 3.0)
Target: x86_64-pc-linux-gnu
Thread model: posix

i ll try to switch 3.1 in ubuntu

So, 2.9 vs 3.0. Make sure both versions give you 3.1. I don't know how to do it in Ubuntu... (I'm on a Mac right now)
