Xcode 4.6 breaks rvm

[lifeiscontent]

when trying to install a version of ruby with xcode 4.6 installed I get this error.

Aarons-MacBook-Pro:Workspace lifeiscontent$ rvm install 1.9.3

Can you try again and post the output of /Users/lifeiscontent/.rvm/log/ruby-1.9.3-p374/make.log?

[lifeiscontent]

yep, 1 sec. Also if it matters here is my brew config since it gives some useful specs.

you are using clang according to this ticket http://bugs.ruby-lang.org/issues/5883 - it's not "fully" supported - you need to try using gcc-4.2, you get instructions for homebrew with running rvm requirements.

[lifeiscontent]

awesome, this fixed it. thanks @mpapis

[eshustrov]

I would like to get Ruby source code to be fixed instead. ruby-1.9.3-p327 compiles with Xcode 4.6 just fine. The problem start just with ruby-1.9.3-p362.

This is not the place to report issues with ruby.

@eshustrov you can report bugs for Ruby here: http://bugs.ruby-lang.org/

I feel silly not reading the documentation. rvm requirements is indeed all you need.

[briankulp]

For the record, since it wasn't explicitly stated, once you add all of the rvm requirements that are listed, running rvm install 1.9.3 --with-gcc-4.2 will do the trick! Thanks for the help!

[mpapis]

@briankulp RVM will detect gcc-4.2 from different sources and prefer it over clang - so it is not required to specify --with-gcc-4.2 - also this is not a flag in RVM or Ruby so it most likely has no effect, the valid flag is --with-gcc=gcc-4.2.

[cliffrowley]

Yep, just installing the requirements is enough. Built and installed fine. Runs fine.

[crosson]

--with-gcc=gcc-4.2 didn't work for me. (Not in PATH) --with-gcc=gcc did

[mpapis]

@crosson gcc as the LLVM compiler should work fine with ruby 2.0.0 and newer, for older rubies it was preferred to use gcc-4.2 which was producing more stable binary and avoided compilation warnings which you would get with clang. basically rvm get head should work in most cases, there are two new tickets to improve error detection especially #1650 and #1651

[aespaldi]

I upgraded to XCode 4.6 and then could not install ruby-1.9.3-p357. I tried installing rvm requirements without success, but after running rvm get head and then rvm requirements I was able to install just fine.

[tuxmea]

I had the same problem.
My solution: --with-ggc=gcc-apple-4.2
Using gcc-apple-4.2 from macports.
