[MacRuby-devel] MacRuby build issues with LLVM

[Scott Guelich]

Nick and group,

I'm seeing similar errors with the newest MacBook Pro -- after simply downloading the 1.9 binary and running macgem, macirb, or macrake. In other words, I'm not compiling from source, just trying to use the latest binary distribution on a core i7 laptop.

$ sudo macgem install rack

Interestingly, the macruby interpreter runs without error. "macgem --help" and "macgem --version" also run fine (but these options produce errors with macirb or macrake).

FWIW, I only have Xcode 4 DP2 installed on this machine... although I assume the MacRuby framework doesn't have any runtime dev tool dependencies? (My understanding was it could be bundled with apps and distributed to end users who don't have dev tools installed.)

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.

It's in the part of the build where miniruby is used to compile rbconfig.rb, and I've separated the output here:
