Failed to install rvm 1.9.3 using xcode 4.3.2

Question

If I type xcodebuild -version , it recognizes that I have xcode installed:

Xcode 4.3.2 Build version 4E2002 

But then when I try to check the rvm requirements , I get the following:

 Notes for Mac OS X 10.7.3, No Xcode. For JRuby: Install the JDK. See http://developer.apple.com/java/download/ # Current Java version "1.6.0_26" For IronRuby: Install Mono >= 2.6 For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba' You can use & download osx-gcc-installer: https://github.com/kennethreitz/osx-gcc- installer ** NOTE: Currently, Node.js is having issues building with osx-gcc-installer. The only fix is to install Xcode over osx-gcc-installer. We had reports of http://hpc.sourceforge.net/ making things work, but it looks like not easiest/safest to setup. To use an RVM installed Ruby as default, instead of the system ruby: rvm install 1.8.7 # installs patch 357: closest supported version rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system.gems # migrate your gems rvm alias create default 1.8.7 And reopen your terminal windows. Xcode 4.2: * is only supported by ruby 1.9.3+ using command line flag: --with-gcc=clang * it breaks gems with native extensions, especially DB drivers. 

It doesn't seem to recognize my xcode, and when I try to install rvm 1.9.3 , I get:

Halting the installation. 

Now, if I read the log, the output of cat / Users / sikandarshukla / .rvm / log / ruby-1.9.3-p125 / configure.log is as follows:

and the output of cat / Users / sikandarshukla / .rvm / log / ruby-1.9.3-p125 / yaml / configure.log is as follows:

Any ideas what to do, thanks for your help

This is a mistake in recognizing the version of Xcode, I created a ticket, and it should be resolved soon → https://github.com/wayneeseguin/rvm/issues/846

All Xcode 4.2+ have the same problem:

4.2

• only ruby ​​1.9.3+ is supported using the command line flag: --with-gcc = clang
• it breaks gems with native extensions, especially with DB drivers.

To solve the problem, use osx-gcc-installer:

You can use and download osx-gcc-installer: https://github.com/kennethreitz/osx-gcc-installer
