[MacRuby-devel] MacRuby build issues with LLVM

[Joshua Ballanco]

Nick,

I'm currently using Homebrew's llvm with MacRuby. Try passing the
"--universal" switch when you install llvm (i.e. "brew install llvm
--universal"). You also might try building and installing clang at the same
time (i.e. "brew install llvm --universal --clang") and see if clang can
compile a simple C hello world to rule out llvm bugs.

Cheers,

Josh
