Trying to install ruby 2.1.2 with rbenv on OSX BUILD FAILED

Question

So, as the title suggests, I'm trying to install ruby 2.1.2, altough I've tried to install other versions as well, and I'm getting the same errors. I'm running OSX 10.9.2.

I've tried:

Installing a fresh gcc compiler, via brew install gcc47

Installing updated OSX command line tools

Uninstalling rbenv and trying again

Restarting the machine

Here is the sum of what I'm getting:

rbenv install 2.1.2

Answer 1

I was able to build it using:

CONFIGURE_OPTS="--disable-dtrace" rbenv install 2.1.2

Basically that's what is suggested in the question's comment by wicz .

The solution by KurtPreston did not work for me. Also using OS X 10.9.

Answer 2

I was able to get this working in my own environment by:

1. Removing the gcc installed by Homebrew: brew remove gcc47
2. Re-installing the XCode Command Line Tools from the XCode Downloads page at https://developer.apple.com/downloads

Answer 3

I was trying to install 2.0 and ran into the same error. However now the CONFIGURE_OPTIONS override doesn't seem to work anymore with rvm at least, so I needed to build it with rvm install --reconfigure -C --disable-dtrace ruby-2.0.0-p594 . This was the first Google result off the error message ("dtrace: failed to compile script probes.d: Preprocessor not found") so I figured I should add this as a current solution for rvm users. Running on OSX Mavericks.

Answer 4

I cannot reproduce this on my machine, sorry. For reference, here's my dtrace version if that should have anything to do with the error:

dtrace -V
  dtrace: Sun D 1.7

You can try to check for XCode and command line tools updates. GCC 4 should not be necessary, you can use the compiler that ships with XCode:

brew uninstall gcc4

Finally, update everything and try again:

brew update
brew upgrade rbenv ruby-build
rbenv uninstall 2.1.2
rbenv install 2.1.2

If that does not work yet: some people have reported that a simple reboot of the machine solved similar errors with dprobe/dtrace.
