I recently updated to OS X 10.7.3 and RVM 1.10.3. The OS X update seems to have confused rvm by changing to a different compiler, resulting in ‘rvm install’ falling with this error:
The provided compiler ‘/usr/bin/gcc’ is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`.
The solution that worked for me to install 1.8.7 was to tell rvm which compiler to use:
CC=/usr/bin/gcc-4.2 rvm install 1.8.7
This worked as expected.
However, trying to install 1.9.2 or above using the same method failed. So, i tried reinstalling Xcode, to no-avail. I then uninstalled Xcode devtools (sudo /Developer/Library/uninstall-devtools) and installed osx-gcc-installer. After this, i was able to install 1.9.2 using ‘CC=/usr/bin/gcc rvm install 1.9.2′, but it reported errors
Ruby ‘ruby-1.9.2-p290′ was build using clang – but it’s not (fully) supported, expect errors
Let’s see how well this works out. If i get errors, there must be a different compiler i can force rvm to use.
Well, the lack of Xcode devtools resulted in this error when Installing rmagick (2.13.1) with native extensions:
checking for stdint.h… *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
So, i re-installed devtools and tried again. Let’s see how well this works.
Update
1.9.2 is working fine, but 1.8.7 is raising this error:
~/.rvm/rubies/ruby-1.8.7-p358/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault
Time to investigate what’s going on here!
1. rvm uninstall 1.8.7 && CC=/usr/bin/gcc-4.2 rvm install 1.8.7
Same error: ~/.rvm/rubies/ruby-1.8.7-p358/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault
2. rvm uninstall 1.8.7 && CC=/usr/bin/gcc-4.2 rvm install ruby-1.8.7 –force
Same error: ~/.rvm/rubies/ruby-1.8.7-p358/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault
3. rvm install ree
Worked!
So, it seems that this setup requires ree
