Bug #7817: (Unable to compile Ruby 2.0.0-rc2 on OSX (clang version 2.1)

• Status: Rejected
• Assignee: mrkn (Kenta Murata)
• Target version: 2.0.0
• ruby -v: 2.0.0-rc2

[injekt (Lee Jarvis)]

clang -v returns

Apple clang version 2.1 (tags/Apple/clang-163.7.1) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin12.2.0
Thread model: posix

Here's the make output:

https://gist.github.com/injekt/4e26a6dee2ce42fc463d

The same version compiles fine with gcc on the same system, and reportedly compiles without issues on more recent versions of clang

Thank you for your report. Were you able to compile rc1 successfully?

I recommend to use latest compiler. Following one works fine at least.
Old clang has plenty bugs.

Apple clang version 4.0 (tags/Apple/clang-421.0.57) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin12.2.0

I believe I did compile rc1 successfully but I can't reproduce since I have updated clang, chances are it probably doesn't compile properly, though.

I understand using an older version of clang would be an issue and that's fine, but we should state this in the install documentation somewhere, otherwise people using an older clang version having segfaults installing Ruby may not know to check this.

mrkn, what do you think?

As I wrote in #5076, CRuby requires "Apple clang version 3.0 (tags/Apple/clang-211.10.1) (based on LLVM 3.0svn)" or later.
It is bundled with Xcode 4.2.
If you want to build old Xcode, use --with-gcc=gcc-4.2.

Old clang has many bugs like http://llvm.org/bugs/show_bug.cgi?id=8319

Compiling Ruby 2 RC2 with the latest Xcode fails on OSX 10.8.2.

You did not build with clang.

[nobu (Nobuyoshi Nakada)]

Yeah, I did see this error with apple-gcc42.
Is it still alive, and is the fix needed?
