I'm getting a configure error when trying to compile Ruby 2.1.3 on OSX 10.10 Yosemite beta 3.

Any ideas?

I was able to work around this by prepending the ./configure command with CC=/usr/bin/gcc

CC=/usr/bin/gcc ./configure --prefix=/Users/jh/.rubies/

Could you show config.log?

[hsbt (Hiroshi SHIBATA)]

What version of your xcode? I couldn't reproduce OSX 10.10 with xcode 6.1 beta2.

[jamonholmgren (Jamon Holmgren)]

My config.log is here: https://gist.github.com/jamonholmgren/0c9921561daafe89bf23

Note that I put both error and successful config.log in there. The error was without the CC=, the successful was with it.

Xcode Version 5.1.1 (5B1008). I had XCode 6.1 beta 2 installed but uninstalled it two days ago because it was taking up too much space and I wasn't using it.

xcode 5 isn't support to Yosemite. Please upgrade xcode.

Thank you, Hiroshi Shibata. Will do.
